What to Do When the Cadillac XT5 Displays 'Transmission Service Required'?
1 Answers
If the XT5 suddenly displays 'Transmission Service Required', it is recommended to directly visit a 4S dealership for diagnostics to check the fault codes. Common transmission issues include: 1. Transmission fluid leakage. Oil seepage from the transmission housing or oil pan could be due to aging seals causing poor sealing or manufacturing defects resulting in porosity in the housing. 2. Clogged transmission inlet filter screen; severe oil circuit leakage; damaged oil pump. During driving, gear shifting may feel jerky or abrupt, which are common symptoms of automatic transmission problems, potentially caused by contaminated transmission fluid leading to valve body sticking. 3. Transmission slippage, lack of acceleration power; water ingress in transmission. While driving, if the engine revs without corresponding speed increase and the vehicle feels sluggish, this is often due to burnt clutch plates. Water entering the transmission from external sources (e.g., radiator cross-contamination or via the transmission vent cap) can cause abnormal transmission operation.
