Well I think that I am posting in the right kind of transmission I am not sure it is for my 2001 GTP. The problem that I am haveing is on the highway. When I let off the gas the car seems to shift in to overdrive. If I am going 65mph at 3000 rpm's and let off the gas the car seems like it shifts and goes to about 1000 rpm well the problem is that when I step back on the gas there is nothing till I hit 3000 rpms again. when it is at 3000 rpm I can shift the car to 3rd with the shifter and there is no change. THis sucks. All other gears seem to work perfect stong shifts all the way through. THe car runs and drives perfect otherwise. AN I love the Car so any help would be greatly appreciated
