1990 Geo Prizm Problems

Worn Shift Bushings Will Cause Manual Transmission to Pop Out of Gear

On vehicles with a manual transmission, worn shift bushings can cause the transmission to pop out of gear, especially when coasting down in 1st or 2nd gear. Replacing all the shift linkage bushings is pretty straight forward and not expensive and will commonly correct this concern.

Automatic Transmission May Not Shift Correctly at High Mileages

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.

Hesitation or No Start Due to Internal Distributor Fault

The ignition coil inside the distributor may fail. Our technicians tell us this may result in a hesitation on acceleration, especially when the vehicle is warming up on cold, rainy days. The pickup coils inside the distributor can also fail and cause a no-start condition. There have also been some failures of the radio noise suppressors inside the distributors, which can short out. Our technicians recommend replacing the whole distributor with a complete, genuine Toyota distributor if any of its components fail.

300,520 miles Iand counting. I swear to you I have never changed anything on this vehicle. Ok maybe; the clutch, timing belt, radiator and put new seals on the front and rear main but other than that nothing.Oh wait oil lots of oil. I bought this car in Detroit in 1991,it has proven to me. that Toyota rocks.
I have only had this car for less than 2 years. I bought it with 137000 miles on it, and in the year and a half I have owned it, added 50,000 miles. The only real flaws I have noticed with it is that the AC doesn't cool down the car at all. It only cools down the person sitting right in front of it. My little prizm finally broke down a few weeks ago because of the master cylinder. I fixed it fo...
I have over 266,000 miles on this car. Very good car. Gets about 38 MPG. Will probably fix the car if it breaks since can't afford to buy another used car right now. Has manual transmission, no AC, heater takes awhile to heat up inside of car. Driver side front window doesn't work properly and probably can't be fixed since part needed now is obsolete but overall a GREAT car. So far, gets ...
