Thread: TC lockup/unlock problems? tranny rebuild ?'s trannyman step in!

Trannyman do you think your bushing kit is necessary, as well as a full bearing kit for, input piston as well, for a typical tranny at 70k

There are a handful of bushings that are very common to be worn and should be replaced. They generally arent worn badly, but worn to the point that they should be replaced, especially if the trans is going to be apart for a full rebuild. The stator support bearing should definately be replaced regardless of mileage as it is a known failure point and not only can cause whining noises but also cause wear on the drive sprocket bearing race. The input piston is a coin toss but likely worn at 70K. I have torn apart 150K mile transmissions with a good input piston, and on the other hand I have taken apart 40K mile transmissions with a badly worn one. If it looks fine then it is safe to use.
