I had Kevin rebuild a turbo 350 for a 72 4x4 with 468 hp and 498 lbs of torque in 2009. I am hard on vehicles and this transmission has given me know problems what so ever to date 2/22/13. I waited to write this well overdue review until i gave his workmanship a good test. When i took it in and left its for the first service, Kevin called me and said he was pulling the tranny out because there was something he didnt like. he put it back together and reinstalled it at no cost to me. i had no idea there was a reason to pull it but he wanted to make sure it was perfect. As i said before i have had no problems with it driving daily in Oregon where i now live. T.R.C. stands behind its warrantees and i have and will continue to recomend them as quality transmission builders. Allen Wright
