I have a 96 pontiac sunfire (work commuter) thats having shifting probs and throwing the GM trouble code "1810: TFP Valve Position Switch Circuit Malfunction". Anyone know what the crap this means and how to fix it? Im assuming it has something to do with the shift solenoids in the tranny. After slowing down then speeding back up it acts like its falling out of gear and not getting back in until it revs a second or you just give it a second to catch up.
