Transgo shift kit.

[ROGELIO A GUZMAN]

Does anyone have any experience with before and after. Is it worth the investment?
My Denali is AWD and shifs fine. Jsu wondering if anyone feels a difference in performance.

Ive run yhe hd2 kit in several 4l60e transmissions and love it. Depending on mileage, you may need to replace your separator plate as well since the check balls can beat it up pretty good.
I usually set all the springs and holes to the towing setting for ones i do for friends. Unless they specifically ask for the 3rd level....it can get jerky though with the race settings. Overall, id do it.
