i bet the previous owner had a programmer too, the dealer said they changed all filters and fluids, so i have never replaced that filter. I just picked it up less than a month ago. Im raeding my codes with the GM tech 2, a guy that works at GM is doing that for me. We think its the speed sensors, but im looking on this these forums and guys saying the P0735 is a dirty trouble code, its the C3 clutch discs that are damaged in the allison and that i better save for a tranny rebuild. What do you think.
