4t60e shift improver....... for lack of a better word
When you do this mod is it necessary to swap out the 1 -2 springs with the 2 - 3 springs? This has been mentioned on a few other forums (Club GP). This just firms up the 1 - 2 shift a bit more. My Supercooler arrived this morning so i will be going out to get some spacers and get nice and oily this afternoon.
