My sunfire cuts out at low rpms but runs fine at high rpms I have recently replace the coils

SOURCE: 1995 sunfire wont shift gear

There were two different automatic transmissions in the Sunfire that year,the 3 speed trans designated the 3T40,and the 4 speed trans designated the 4T40.If your car has the 4 speed trans,there will be a circle around the "D" on your gear selector indicator.The 3 speed trans will not have a circle around the "D".The 3 speed trans works off of a cable called the TV or Throttle Valve cable.This cable should be checked where it engages the throttle body around the area where the throttle cable attaches to the throttle body,on the engine.If the cable becomes disconnected for whatever reason,the trans will not shift out of 1st gear in most cases.If the car has the 4 speed trans,this model trans is totally electronic,and the vehicle should have the codes pulled out.For every trouble code,there is a diagnostic route to follow to repair the malfunction.
