My C6 in my truck is starting to slip so I think a rebuild is in order. My question is can I swap in an newer style overdrive tranny in my 85 4x4? I want to keep the auto becouse my other two trucks have the hog leg and im tired of shifting gears. SHould I just keep the c6 or would the swap to an od be worth it? I was thinking of a gear spliter unit but I dont have the funds for that so I will have to be resourceful on this one. Any advice would be greatly apreciated. sorry for the miss spelling , my fingers are could and dont want to work right.
