The pressure solenoid went out on my monte at 88500 miles. shifting became erratic and eventually it failed to shift at all. complete rebuild had to be accomplished due to over pressures screwing everything else up.

don,t go n overdrive
I bought this car used with 100000 on it. The day I drove it off the lot it started shifting harshly accelerating and decelerating. I ended up getting the Pressure Control Solenoid replaced and that solved the problem. Now at 125,000 mi I am experiencing a different problem with erract shifting and I am hoping its not going to cost me another $700.
