Helped a buddy out and tightened up his 09 CTS-V tranny as it was flaring awful after mods...
Mission accomplished, except when in sport mode, it still has a slow shift only on 2-3.
The 2-3 in normal mode is 150-175ms & push it into sport mode and its 500ms? All other shifts in both modes are tight & delivered TQ is correct.
As always, your expertise is appreciated!
