When the engine/transmission is cold you stick it in gear and the car pulls fine but as it warms up, it's like the clutch is slipping and it won't go anywhere. I can't be sure but I think there may be a small leak somewhere on the trans does this sound likley?
I've never owned a yank before so this is all pretty new to me. Does anyone know of any specialist around Croydon who may be able to help me out

Any help gratefully recieved, thanks Nick.
