What Is New: Mitsubishi Pajero remains a popular vehicle across Dubai, Abu Dhabi, Sharjah, and the wider UAE, valued for its durability and off-road capability. As these vehicles accumulate mileage in extreme heat conditions, Mitsubishi Pajero transmission fluid leaks have become a common concern for owners in the Emirates, particularly during summer months when temperatures exceed 48°C.
Service centers across Al Quoz in Dubai and industrial areas in Abu Dhabi and Sharjah report increased inquiries about transmission fluid leaks during peak summer. Understanding the causes, detection methods, and repair options helps UAE vehicle owners make informed decisions about maintenance and repairs. This guide covers seven key facts about Mitsubishi Pajero transmission fluid leaks, with estimated repair costs in AED relevant to service centers throughout the Emirates.
Author Credentials: This guide is prepared by Noorhan’s transmission service team, which supports vehicle owners, independent workshops, and transmission specialists across Dubai, Abu Dhabi, Sharjah, and the wider UAE and GCC region.

1. Multiple Leak Sources Exist Beyond The Transmission Pan
Transmission fluid can leak from several different locations, not just the transmission pan. These locations include the transmission pan gasket, transmission cooler lines running to the radiator, transmission front pump seal (input shaft seal), torque converter seal, transmission output shaft seal, transmission vent tube, transmission filler tube seal, transmission drain plug seal, and transmission case seals. Each location requires different diagnostic procedures and repair approaches.
A pan gasket leak is typically less expensive to repair than a front seal leak, which may require partial transmission removal. Understanding that Mitsubishi Pajero transmission fluid leaks can originate from multiple sources helps owners avoid assumptions about repair costs before proper diagnosis is complete.
Many vehicle owners assume that any transmission fluid leak indicates transmission failure requiring replacement. However, identifying the exact leak source through visual inspection, pressure testing, or dye tracing determines whether a simple seal replacement is sufficient or more extensive work is needed. Correct diagnosis helps prevent authorizing repairs that may not address the actual problem.
Key Takeaway
If your Pajero shows transmission fluid leakage, request diagnostic testing to identify the exact leak source before authorizing repairs. A written diagnostic report should specify the leak location identified, testing performed, recommended repair, and estimated cost. Diagnostics typically take 1-2 hours and cost less than authorizing repairs without knowing the actual problem.

2. UAE Heat Affects Transmission Seals And Gaskets
Transmission seals and gaskets are rubber components that can harden, crack, and lose effectiveness when exposed to prolonged high temperatures. In Dubai, Abu Dhabi, and across the UAE where summer temperatures reach 48-50°C (with even higher temperatures on asphalt surfaces), transmission fluid temperatures can exceed safe operating ranges during heavy driving or stop-and-go traffic.
Elevated temperatures can accelerate rubber degradation. Transmission seals that remain functional for extended periods in temperate climates may degrade faster in UAE conditions. This is related to how rubber compounds respond to heat exposure rather than a manufacturing defect.
Additionally, transmission fluid itself can break down faster in heat. Transmission fluid is engineered to operate within a specific temperature window. Outside this window, the fluid’s lubricating properties may degrade. Degraded fluid may not cool internal components as effectively, potentially contributing to further temperature increases.
Seal degradation is typically progressive rather than sudden. Early warning signs may include slight transmission fluid spots appearing periodically, slight transmission fluid odor, or transmission fluid level dropping gradually between services. These signs may appear before complete seal failure, providing time for inspection and preventive action.
Key Takeaway
Monitor your Pajero transmission fluid level regularly during summer months using the dipstick. If fluid level drops noticeably between services, a leak may exist and should be diagnosed. Do not rely on repeated top-ups to solve the problem. Continued driving with a leaking seal allows fluid level to drop, potentially causing internal damage. Early seal replacement is generally less expensive than addressing damage from prolonged low-fluid operation.

3. The Transmission Pan Gasket Is A Common Leak Source
The transmission pan gasket, which is the seal between the transmission fluid pan and the transmission case, is a commonly reported source of Mitsubishi Pajero transmission fluid leaks. The pan gasket can wear from thermal cycling (repeated heating and cooling), dirt contamination, improper installation during previous service, or pan corrosion from environmental exposure.
Symptoms that may indicate pan gasket leaks include a puddle of dark reddish-brown fluid under the transmission area when the vehicle is parked, a distinctive transmission fluid odor, or fluid spots on the underside of the vehicle. Pan gasket leaks are typically gradual rather than sudden, which may provide time for diagnosis and repair before fluid level drops critically low.
However, delaying repair of any transmission fluid leak allows fluid level to drop over time. Low fluid can cause internal transmission friction, potentially damaging bearings and other components. What starts as a gasket replacement may escalate to more extensive repairs if the leak is ignored for extended periods.
Key Takeaway
If you notice transmission fluid spots under your Pajero in the transmission area, address them promptly. A pan gasket replacement involves draining the transmission fluid, removing the pan, replacing the gasket, reinstalling the pan, and refilling with correct fluid. This repair is generally straightforward when addressed early. Delaying allows fluid level to drop, potentially causing additional problems.

4. Transmission Cooler Line Leaks Require Prompt Attention
Transmission fluid is circulated from the transmission to an external transmission cooler (usually mounted near the radiator) through hoses called transmission cooler lines. Over time, these hoses can crack from heat exposure, vibration, or contact with other components. A crack in a cooler line allows pressurized transmission fluid to escape, potentially causing rapid fluid loss.
Unlike pan gasket leaks which are typically gradual, cooler line leaks can escalate quickly. A vehicle might lose significant fluid within a short driving period, causing rapid transmission temperature increase. This makes cooler line leaks more urgent than some other leak types.
Symptoms that may indicate cooler line leaks include sudden drop in transmission fluid level, transmission temperature warning, visible spray pattern of reddish fluid near the cooler or radiator area, or transmission shifting problems as it overheats from low fluid.
Key Takeaway
If you notice sudden transmission fluid loss or spray patterns under your transmission cooler area, avoid continued driving and have the vehicle inspected promptly. Transmission cooler line replacement involves locating the damaged section, disconnecting both ends, installing a replacement hose, and refilling transmission fluid. Addressing cooler line leaks quickly helps prevent the more expensive repairs that can result from continued operation with low fluid.

5. Faulty Thermal Sensors Can Cause False Warnings
The transmission front seal is located where the engine and transmission connect. It prevents transmission fluid from leaking into the engine bay area. If this seal fails, transmission fluid may escape from the bell housing area, appearing as a leak between the engine and transmission.
Replacing a front seal typically requires significant work because the seal is not easily accessible. The transmission may need to be partially or fully removed to access the seal location. This makes front seal replacement more labor-intensive and more expensive than external seal or gasket replacement.
Front seal leaks can result in notable fluid loss. The leak may drain significant fluid during operation, potentially causing transmission problems before the leak is even noticed.
Symptoms that may indicate front seal leaks include transmission fluid appearing in the bell housing area (between engine and transmission), transmission overheating during normal driving, or transmission slipping or shifting harshly from low fluid pressure.
Key Takeaway
If you identify transmission fluid leaking from the bell housing area, address the leak promptly. Rapid fluid loss from front seal leaks can cause problems within a short period. Front seal replacement requires transmission work and is best handled by service centers with proper lift equipment and experience. Mitsubishi Pajero transmission fluid leaks from the front seal area should be diagnosed to confirm the leak source before authorizing the repair.

6. Low Transmission Fluid Causes Internal Damage
Transmission fluid serves two functions. First, it lubricates internal gears, bearings, and other components. Second, it generates hydraulic pressure to engage clutches and operate solenoids. When fluid level drops due to leaks, both functions are affected.
Low fluid reduces lubrication. Metal components may begin generating friction and heat. Low fluid also reduces hydraulic pressure. The transmission may not hold gears firmly, causing slipping (a sensation of lost power momentarily while accelerating). Continued driving with low fluid causes internal component damage that accumulates over time.
The damage from low fluid operation is not always immediately apparent. A transmission might slip occasionally but still function for some time before more serious problems develop. During this period, internal damage may be compounding. By the time the transmission fails completely, the internal damage may be extensive enough that seal or gasket replacement alone cannot solve the problem.
Topping up transmission fluid provides temporary improvement, but if an underlying leak exists, fluid level will drop again. The solution is addressing the leak, not perpetually topping up fluid.
Key Takeaway
Do not ignore transmission fluid level drops or slipping symptoms. If your Pajero transmission slips or if fluid level drops noticeably between services, the transmission may be experiencing low-pressure damage. Address the leak promptly. The longer you wait, the more internal damage may accumulate. Early intervention often helps prevent the need for more extensive repairs.

7. Regular Maintenance Helps Prevent Transmission Leaks
Transmission leaks can often be reduced through proactive maintenance. Transmission fluid degrades over time. Old fluid may contain metal particles, deposits, and contaminants that can affect seal and gasket condition. Transmission filters trap contaminants. A clogged filter can restrict fluid flow, potentially creating pressure issues. Transmission cooling systems can accumulate dirt. Restricted cooling can cause elevated fluid temperatures, which may accelerate seal wear.
Maintenance steps that may help include changing transmission fluid according to manufacturer recommendations using the correct fluid type, replacing the transmission filter during fluid changes, cleaning or flushing the transmission cooler periodically, and checking transmission fluid level regularly.
These maintenance steps represent a relatively modest ongoing cost and may help prevent seal failures that would be more expensive to repair.
Key Takeaway
Consider establishing a transmission maintenance schedule. Change fluid according to your owner manual recommendations, replace filters during fluid changes, and check fluid level regularly, particularly during summer months when heat stress is highest. This preventive approach may help extend transmission life and reduce the likelihood of Mitsubishi Pajero transmission fluid leaks developing.

How To Detect Transmission Fluid Leaks
Diagnostic Methods Overview
| Detection Method | Estimated Cost (AED) | Time | What It May Identify |
|---|---|---|---|
| Visual inspection | 50–100 | 15 min | Obvious leaks, puddles, visible damage |
| Transmission pressure test | 100–200 | 20–30 min | Internal pressure issues, pump concerns |
| Transmission fluid analysis | 150–250 | 30 min | Fluid condition, contamination |
| UV dye tracing | 200–300 | 45 min | Precise leak location, hidden leaks |
| Cooler flow test | 150–200 | 25 min | Cooler blockage, line restrictions |
| Complete diagnostics | 400–600 | 2 hours | Integrated system analysis |
Costs are estimates and may vary by service center and location.
Step 1. Visual Inspection
With the vehicle parked on a clean surface, inspect the transmission pan area, cooler lines, and bell housing area for wet spots, fluid residue, or active dripping. A fresh leak often shows as a shiny wet spot. Dried leaks appear as dark stains. The leak source is typically above the wettest area. This inspection can identify obvious problems.
Step 2. Check Transmission Fluid Level
Consult your owner manual for the transmission dipstick location. Check fluid level with the transmission at operating temperature (after driving). If level is below the minimum mark, fluid is low and leakage may be occurring. After topping up, observe whether level drops again within a few days, which would confirm an ongoing leak.
Step 3. Pressure Testing
A transmission specialist can connect pressure gauges to test ports and record pressure readings with the engine running and transmission in different gears. Abnormal pressures can indicate low fluid level, worn pump, clogged filter, cooler blockage, or internal issues. This testing helps identify whether pressure is contributing to the problem.
Step 4. Fluid Condition Analysis
Transmission fluid can be analyzed for color (red is healthy, brown indicates aging, black indicates severe degradation), metal particle content, moisture content, and viscosity. This analysis can indicate whether internal damage is occurring or whether the fluid simply needs changing.
Step 5. UV Dye Tracing
A technician adds UV fluorescent dye to the transmission fluid. After driving, a UV light is used to inspect components. The dye glows at leak locations, helping pinpoint exact leak sources that visual inspection might miss. This method is particularly useful for small or hidden leaks.
Key Takeaway
If transmission fluid level is dropping or you suspect a leak, request diagnostic testing before authorizing repairs. Comprehensive diagnosis identifies the exact leak source, allowing appropriate repair decisions. Many service centers can complete diagnostics within 1-2 hours.

Frequently Asked Questions
What color is Mitsubishi Pajero transmission fluid?
OEM transmission fluid is typically bright red when new. As it ages, the color gradually darkens to deeper red, then brown. Black fluid indicates severe degradation or contamination. If you observe very dark fluid on your dipstick or under the vehicle, the fluid should be evaluated and the transmission inspected.
How much transmission fluid loss is normal?
Modern transmissions in good condition should not lose measurable fluid between service intervals. Any noticeable fluid level drop suggests a leak that should be investigated.
Can transmission fluid leaks seal themselves?
No. Unlike some engine gaskets, transmission seals and gaskets do not self-seal. A crack or worn seal will continue leaking until repaired. Fluid level will continue dropping until the leak is addressed.
Is transmission fluid leak covered by warranty?
Coverage depends on vehicle age, mileage, warranty terms, and whether the leak results from a manufacturing defect or normal wear. Check your warranty documentation for specific coverage information.
Can I drive my Pajero if the transmission is leaking?
For short distances with a slow leak, yes, but continued driving allows fluid level to drop. Every distance driven with low fluid potentially causes additional wear. Address leaks promptly to minimize the risk of internal damage.
What happens if transmission completely loses fluid?
Without lubrication, internal gears and bearings generate extreme friction and heat. The transmission may seize, preventing the vehicle from moving. This typically requires transmission replacement.
Can aftermarket products stop a transmission leak?
Aftermarket leak-stopping additives are generally not effective for mechanical seal and gasket leaks. Using incorrect transmission fluid can also cause problems. Use the fluid type specified in your owner manual.
How much does Pajero transmission replacement cost in UAE?
Complete transmission replacement including parts and labor can range from AED 5,000 to AED 12,000 or more depending on whether new, remanufactured, or used transmission is installed. This is significantly more expensive than repairing individual leaks, which emphasizes the importance of addressing leaks early.
Can transmission leaks cause warning lights?
If fluid drops low enough to affect transmission pressure or operation, warning lights may be triggered. However, many leaks do not trigger lights until significant problems have developed.
Is transmission slipping related to fluid leaks?
Yes. Slipping (momentary lost power while accelerating) can be caused by low transmission fluid pressure from leaks. As fluid level drops, pressure may become insufficient to hold gears properly. Continued driving with slipping can cause additional internal wear.
What should I do if transmission smells like burning?
Stop driving and have the vehicle inspected. Burning smell indicates fluid temperature has exceeded safe limits, which can occur when fluid level is low, the cooler is blocked, or internal problems are generating excessive friction. Continued driving can cause rapid damage.
Where can I get Pajero transmission service in UAE?
Authorized Mitsubishi service centers in Dubai, Abu Dhabi, and Sharjah have manufacturer diagnostic tools and specifications. Some independent workshops also specialize in transmission service. Ensure the service center has experience with Pajero transmissions. Contact Noorhan for service in Dubai and Abu Dhabi.
UAE Context For Pajero Transmission Issues
Mitsubishi Pajero is popular throughout Dubai, Abu Dhabi, Sharjah, and across the UAE, particularly among commercial vehicle operators due to its durability and cargo capacity. The combination of high ambient temperatures, continuous transmission operation in traffic, and demanding driving conditions creates an environment that can affect transmission seal and gasket longevity.
Summer months (May through September) when temperatures peak place additional stress on transmission components. Vehicles operated in commercial service with extended daily usage may benefit from more frequent maintenance than typical passenger vehicles.
Coastal areas with salt exposure may see additional corrosion on external transmission components. Vehicles regularly driven off-road or in dusty conditions may accumulate more contaminants that can affect fluid condition.
Understanding these local factors helps UAE owners recognize when Mitsubishi Pajero transmission fluid leaks may be developing and take appropriate preventive measures.
Key Takeaway
If your Pajero operates in demanding conditions (commercial service, extended daily use, off-road driving), consider more frequent transmission maintenance. Discussing your specific usage pattern with a service advisor can help determine an appropriate maintenance schedule for UAE conditions.
