Thats what I like to hear
thanks for the info, I did not compare the 2 trannies but I knew the 435 Had a super low gear as well but the T-18 is already in the truck
203-205 and 5.38s in the axles
(I like low gears lol) although if I can get my hands on some rockwells Id rather run those instead of 60's on the J-truck... okay im done hi-jackin his thread
