Jeep Grand Cherokee: Powertrain
Affects Jeep Grand Cherokee · 2005 — about 3K vehicles.
The hazard
On certain vehicles equipped with a 3.7L engine and automatic transmission, water from the air conditioner evaporator drain tube may enter the transmission at the fill tube grommet seal. This can result in shudder during torque converter clutch engagement which, if ignored by the operator, could lead to increased transmission operating temperatures, boiling of the water, and a subsequent purging of transmission fluid into the engine compartment that could lead to a fire. Correction: Dealers will inspect the transmission for leakage at the fill tube grommet seal. If no leak is detected, a new fill tube grommet seal and water deflector shield will be installed, and proper alignment of the fill tube verified. If the presence of a leak is detected, the vehicle will be evaluated for a shudder condition and based on the evaluation, the transmission will either be triple flushed or the torque converter replaced as required and a new grommet seal and water deflector will be installed.
