1993 Geo Prizm LSI. When my car is stopped and going up an incline or slight raise my first gear will move very slowly even if I depress the gas pedal all the way. Until I get about 25mph were it seems to shift into either 2nd or 3rd gear it then will accelerate as though it went into another gear.
My Check Engine Light flashes but I cannot see a pause when it does it so hard to get the exact code number. Could this be a shift Solenoid 1 going bad? I do not have this problem when going downhill at all.

Go to Autozone its a free public service and have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis, finding out what's going on

Correction: its my O/D off indicator that flashes not my check engine light. I think I have a couple of issues very similiar. I was reading the Geo Service Manuel (I always request one when buying a vehicle). I have had issues where when my engine is cold it wont kick into the 4th gear (O/D gear) until the engine has warmed up. According to the manual it states that when your Torque Converter Clutch (TCC) Solenoid is having problems that it wont shift 4th gear until the transmission fluid reaches a certain temperture. This is one issue I have had for about 2 years now. Now the same thing with a lower first gear issue. That is why I think its a Shift Solenoid 1 because it works with 1st gear and 2nd gear only.

I will check out with Autozone. Are these Shift Solenoid's easy to replace? Sounds like you just take off the transmission pan. Disconnect the cable and unscrew the solenoid.

Thanks in advance!
