I have 2005 Gt and I'm have tranny problems I can't shift the car into different gears when the car is running when the car is turned off I car shift through the gears fine I just recently replaced my clutch and pressure plate and slave cylinder about six months ago it's been running fine until about three weeks ago is when this happened I have tried to bleed the clutch but no luck with that any ideas would be great thanks

 

That would normally indicate a clutch issue. A few months ago I had a clutch put in and the pressure plate bolts all backed out cause the same issue. I'm sure it's in the clutch.

 

I am on my second Exedy clutch in 2000 miles. Same symptoms. First a mach600, then a new clutch master, then a mach500.

In two weeks, when BBR does my Hellion, I'll be stepping into an RST.

The drivetrain in these cars are complete crap, to have an added problem from an aftermarket component like a clutch is very upsetting. Too much invested now. If this happens again ( different manufacture) I'll be forced to go automatic..... And possibly question the guy under the car.

 

I've gone through several clutches myself. I feel your pain. I think it's due to crappy slaves. Pretty sure that's what destroyed my Centerforce. I have a dorman slave now and it's been working perfect. If you're talking about getting a twin disc just be careful. I hear they shatter if you slip em.
