I got my 98 GST Spyder about 5 months ago... I ended up putting a new motor in it because a piston ended up hitting a spark plug.. (Dunno how that happened...) But anyways.. Before that happened the check engine light came on and was misfiring.. Also Over drive wouldnt come on when i pushed the button (Automatic By the way) The problem was fixed with a new motor.. Just today... The car wouldnt shift into overdrive, and when i take off from a stop it seems like the car is stuck in 4th gear... It doesnt shift at all and I can't turn overdrive off or on with the switch again.. Keep in mind it stays in 4th gear all the time.... Even at hi speeds... I can't take the car much over 60 or it will get into high rpms(Which I think happened last time).
I also put in new gauges on the dash.. Which I don't think would have done anything... But nothing else has been done...


So I'm thinking its either something with the wiring...

or even worse, that the tranny is crap...

Anyone deal with this or hear anything about it? Im still clueless what to try at this point so far...

 

Anyone know whats goin on here?
