I have just started to have some problems with the transmission in my 98
Grand Prix GTP.
When I am driving along at steady state and accelerate lightly, the RPM will
flare up about 500 RPM and then come back down within a second or so. It
seems like the torque converter lockup clutch is disengaging briefly and
then re-engaging. I am suspecting throttle position sensor or a solenoid
or... Who knows.
The car has about 200,000 KM on it and is otherwise in great shape. No other
issues and runs very well.
Any thoughts on this are appreciated as I don't really trust many shops out
there and prefer to do all the work on my car on my own.
