My car runs very rough in gear. It is hard to get it in gear without stalling. When I do get it in gear the car bucks and run rough. It is fine out of gear. The car does not want to make boost either. After I drove the car for a while and as soon as I put the car in park the RPMs went to 3 grand immediately. It almost seems like the TC is locked. I only have a Scnamaster, so I cannot tell if the TC is lcoked. I might have to borrow a friends Direct Scan or TL. Also, I drove the car 100 miles and the coolant stayed the same. So I do not think it is a HG. I may do a compression test just to make sure. Any other suggestions?
