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.

    The transmission downshifts while driving steady(constant speed) this occures at 60 mph and at 30mph mostly, at least these two speed ranges are the most notable. The shifting is erratic and and does not occure frequently, maybe 2 or 5 times a month. One time at 60mph it shifted from overdrive down to second and the engine rpm jumped up to approx 4000rpm. The GM dealer and 3 garages have been no help.
