1996 Buick Park Avenue Q&A
1996 Buick Park Avenue Question: How do I change the transmission solenoid?wWill it give off a diagnostic code?
Car shifts ok,then when in 4 th gear,kind of shudders or shakes real bad, then goes on ok.usually between 50 and 60 mile per hour.Have checked for codes and there were none,but check engine light on.Seems like trying to pop out of gear,usually I ease off,slow down,car goes on ok.Car has 244,0000,miles.Just every once in a while,more often lately. - tom stevens
seek diagnostic at Aamco transmission and scan for codes. - ebans777
agree with ebans sounds like lock up solenoid is bad - globalhelper
Next time it starts the shudder, lightly apply brake and see if it goes away, let off brake see if it starts again, this is a torque converter test! Post results for more help. - pushrod
