It's good to be back my friends. Seems like a lot of us come back frequently :) I've had a '93 GS, '91 GSX, '95 RS, '96 RS, '92 GST, and now I am on a '91 GST! Some were crappy cars, some I should have NEVER let go (GSX 90K), and some I'd rather forget ('92 GST, two cans short of a six pack ghetto-rebuild by P/O)

Anyway. Auto transmission slips in overdrive and you've got to shift the car manually to engage gears.

Toasted end clutch is the consensus ? Anybody from the PNW order an imported transmission before? Assuming it's rare to find a used automatic turbo tranny in good shape.

Thanks DSM'ers
 
Update: Bought the car. You don't need to shift manually. Car slams into gear and shakes like a wild banshee when stopped. Doesn't do that in neutral/park. Has poly inserts all the way around, but shouldn't be that bad. It also has hard downshifts and lazy upshifts (You have to let off gas a little bit, then it will shift up). Sometimes it starts in 2nd or 3rd gear, and then you've got to womp on it and it will do another hard down shift and go into boost.

Several boost leaks, possibly seal going in turbo or exhaust guides are shot. Hunts at idle when cold, and idles high (1200RPM) when warm. Got my work cut out for me.

I think transmission is shot.

Is it worth rebuilding an auto transmission for 300HP? Any recommendations? Yankin' drivetrain and going to town on the block as well.
