Transmission slams into gear

Dear Doctor: I backed my Acura out of the garage (RL with automatic transmission) without letting it first idle for a few seconds. It backed up fine, then I put the transmission in drive and it slammed into gear. The dealer said this is a normal condition and the transmission pump has to build up pressure. Please advise. Norm


Dear Norm: Transmissions are complex and work with electronics and fluid pressure. The front transmission pump does have to build up pressure before the clutch will engage properly. I would also agree that the condition that you had was normal based on the way the car was instantly driven.
