A: If your transmission has been overfilled it may cause a problem. Transmissions that have too much fluid may often exhibit shift problems and on some transmissions may cause excessive internal pressure. If ignored this may cause damage or create leaks. There is a difficulty that the overfill presents. The majority of transmissions do not have a drain plug therefore it is not an easy task to correct the overfill problem. The transmission pan on the transmission may need to be removed to drain fluid or special equipment to purge the fluid from the transmission.
Q: My transmission appears to be overfilled. Will too much transmission fluid ruin a transmission?
