Geo Prizm Automatic Transmission May Not Shift Correctly at High Mileages

(19 reports)

At higher mileages, (125,000-150,000) the automatic transmission may not shift correctly. This can be caused by the throttle position sensor being out of adjustment or a shift solenoid needing to be replaced. Typically the transmission does not need to be completely overhauled.

On a cold start, the car won't shift into high gears until it has warmed up. My driving is all highway and I'll be cruising at 65 mph in 3rd gear. I can barely hear myself think until it suddenly decides that it should sift. I haven't had it fixed as I've already ordered a new car and don't want to be putting money into this. -
Doesn't want to shift when cold. Used to be just over drive, now it's all gears. Stays in 1st gear for half a block. Takes 2-3 miles to shift into overdrive. -
same problem, will not shift until it warms up to operating temperature -
shifted like a stick shift from 1st to 2nd. -
transmission is an automatic. on the highway, it runs along at 60 MPH in 3rd gear at 3000 rpm, and when I start up a hill, it shifts into fourth, as soon as I head back down the hill, it drops back into third. As this problems persists, my mileage has dropped about 15%, from 38 on the highway down to about 31. -
My car can't even pick up the second shift!:-/ -
Major forward gears slipping. Reverse ok. -
When cold and sometimes not the car will not sift correctly. -
