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.

    My car started to have hard up-shifts after driving a few minutes. It would bang from 1st to 2nd gear, 2nd to 3rd and from 3rd to 4th. Sometimes, if I were to shut off the engine for a few minutes, the problem goes away for a bit.

    I was told that I had to replace the Electronic Pressure Sensor for about $800 (after labor)

    My car jerks occasionally when the transmission shifts. It feels like something breaks when it happens, but then the car runs normal. It does it in town or on the highway. Very annoying.

    Hard shifting from 1st to 2nd gear, then 3rd to 4th gear. The shifting is hard,and noisy. The car literally jerks when its shifting from 1st to 4th gear. Down shifting from 4th to 1st when slowing down or stopping is as expected, smooth and natural.

    Bought vehicle used. Almost right away developed hard upshifts usually 3rd to 4th gear. Changed tranny oil, filter, used additive. Seemed to help, but problem worsened. Most problem in warmer weather (not as often in winter), now get hard up shifts all gears when warmed up, tho occasionally will shift normally. At highway speeds, after getting hard upshifts, also get a whine from transmission - apparently running in high pressure mode.
    Vehicle now has 240,000 + miles on it.

    Hard upshifting after driving over a minimum of 20 min occasionally. No check engine light. Mechanic states pressure control solenoid and valve assembly replacement/repair.
