is there a manual or instrucion sheet anywhere online on how to remove the j-mod? do trannys out of 02 gt's even have the j-mod's? i just got a 02 gt tranny wit 9k miles on it for $200 and before i put it in my car i want to take out the j-mod, just trying to figure out how thanks
Please note that a j-mod HELPS the transmission. It will make it work better and live longer.
I can see no reason to ever undo one. I can see putting springs back in to soften shifts, but the modifications to the valve body should always be done to any 4r70w for a car and never be undone. This stuff should have been done from the factory.
If the tranny is stock, it doesn't have one as several others have pointed out already.
