Transmission Cooling General Specification
Scheme 55
Scheme 56
All vehicles with automatic transmissions are equipped with integral transmission fluid coolers. The integral transmission fluid cooler is contained inside of the radiator outlet tank and cannot be repaired separately. All (AWD) vehicles are equipped with the transmission auxiliary fluid cooler which is mounted in front of the radiator. In operation, transmission fluid travels from the transmission to the integral transmission fluid cooler to the transmission auxiliary fluid cooler then back to the transmission. The integral transmission fluid cooler transfers heat from the transmission fluid to the engine coolant. The transmission auxiliary fluid cooler transfers heat from the transmission fluid to the outside air.
For transmission fluid cooler flow test, refer to TRANSMISSION FLUID COOLER FLOW TEST .
For transmission fluid cooler backflushing and cleaning, refer to TRANSMISSION FLUID COOLER -- BACKFLUSHING & CLEANING .

Inspection & Verification
| WARNING | Never remove the radiator cap under any conditions while the engine is operating. Failure to follow these instructions could result in personal injury and/or damage to the cooling system or engine. To avoid having scalding hot coolant or steam blow out of the radiator, use extreme care when removing the radiator cap from a hot radiator. Wait until the engine has cooled, then wrap a thick cloth around the radiator cap and turn it slowly to the first stop. Step back while the pressure is released from the cooling system. When you are certain all the pressure has been released, press down on the radiator cap (with a cloth), turn and remove. |
Check for fluid leakage. If fluid leakage is found at any of the transmission fluid cooling components, the component must be replaced.
