I just had my transmission done with the DTT VB&TC. I live in alaska so it was hard to find a shop that would do the rebuild to Bill K's standards. Well I found a place to do the work and Bill was happy with them after their phone conversation. I dont know much about transmissions, however with Bill's parts and the excellent job done by the Transmission Center in Wasilla, AK I now have a new truck. WOW is all I could say as I drove away with a truck that responded to the gas pedal. I'm not trying to start any debates just want to give credit where it is due. I'm sure that everyone else makes a great transmission but I am happy with my choice. Thank You Transmission Center and DTT!
