SYMPTON/CONDITION
After starting the vehicle, there is no drive or reverse for an abnormally long period of time (5 seconds or longer), or until shifting gears, or until the
engine is raced. This condition is most likely to occur after a hot soak of approximately one hours. It may also occur after an overnight soak. It is not
always repeatable.
DIAGNOSIS
Test the transaxle for engagement into drive and/or reverse after a hot soak. If there is no engagement for an abnormally long period of time (5 seconds
or longer), or until shifting gears or until the engine is raced, and if subsequent operation is normal, do the following repair.
