I have a 96 GP that just developed a sudden trans problem. A little background first. It's a 3.1 L with 80 K miles. No mods, daily driver. Engine a trans have run like a watch to date.
Then yesterday... Upon startup, car slips like mad in drive. Feels like it's got almost no clutches. Revs to 4,000 plus in D on the brake. Shifting to 1st, it has a little more bite. Revs to maybe 3,500. Still slips like mad. No funny noises. However, in reverse, all is normal. Trans pulls hard. Can't hold the car against the brake.
Fluid level is OK and is still a dark red. No burnt smell.
Car is throwing a code (service light on dash) but I don't have a code reader yet (one is coming tomorrow).
Problem happened immediately with no warning, and reverse is strong so I tend to doubt a bad pump or clutch pack.
I'm an old hand wrencher. Built lots of cars, motors and rebuilt more than a few trans in my time, but all old school. Nothing with computers, till now.
If this were a TH 350 or 400, I'd suspect a valve body, but it isn't.
Anyone got any advice on where to start, or do I need the code first?
Thanks...Steve
