Chevrolet Monte Carlo Problem Report
Chevrolet Monte Carlo Erratic Shifting of the Automatic Transmission
The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.
Starting at a stop light, it jumps from first into second. Like a slip. When changing into third or fourth(whatever the last gear is) it makes a little skip. sometimes the starting from stop, it CLUNKS loudly. transmission fluid changed, but still does it. - csprop
Lately, the car is having large difficulties shifting, or won't shift at all. We replaced the transmission filter, and got more transmission fluid, but it still has a hard time with shifts when it's exceptionally cold outside. - 619issues
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. - Visitor

Erratic shifting when climbing hills or trying to merge onto highway - Visitor
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. - kristie
