Can anyone enlighten me on when GM improved the sunshell design? My trans is a 2005 and the sun shell has perfect teeth and no signs of cracking at all, I even inspected it under the shop microscope and it looked like new.
I'm only running it behind a stock 4.2 with no performance adds but it will be towing a 5000 lb trailer.
Do I really need a "beast"?
I think I've read that the early sunshells weren't heat treated but that once GM had a lot of warranty replacements they wised up and made improvements to the sunshell. I just don't know when that cut in or if it's enough for a stock rebuild.
The failure of this trans was the pwm valve with the stuck ball and the burned 3/4 clutches, it didn't have anything to do with the sunshell.
