I drive a 2001 Tacoma Pickup and the other day I was backing up into a driveway. It has an auto tranny. Before I backed up I was in neutral going approx. 5 mph but then I accidenty put it in reverse while it was still going forward. The transmission made weird noises and the ride got bumpy all of a sudden but it then started backing up. I felt so bad afterwards becase this is a fairly new truck and I don't want to have a messed up transmission. My question is did I damage the transmission? It was only 5 mph.
