Hi, I have a 93 Protege LX, and the transmission is giving me problems. I changed the Speed and Throttle Position Sensors and it was working when I test drove it on the freeway for 20 mins and it was working fine; however, when I got home the hold light began to flash and has been ever since (when the car is on obviously )

I don't want to get ripped off at a shop, so is there anyone who has had a similar experience that I can learn from? What could be wrong?

Thanks for your help everyone.

 

Im guessing since it has a hold it is auto matic??....I was thinking maybe it could be the button on the shifter maybe setting off the sensor or something it could be loose....thats all i can think of for now...sorry i wasnt very much help...
