Noob Here, So i about to remove some torque management from my tranny. I have heard from many that if i do, i need to repalce GM's crappy reaction shell. If you google this you find a boatload of info! However i have the
4L65e and some have said that GM put a better sun shell in these tranny's. Does anyone know the real story before i pull my tranny out to upgrade?????

2008, 5.3 silverado, 4x4, 4.56 gears, 2800 stall, Comp 275 cam, CAI, Headers, port matched heads, nelson tune, 1.8 rollers, manley rods, etc....

 

I would upgrade to the beast. The 65 shell is still quite weak.
