H3T alpha adv shutter on take off

[dcastell]

Have an (5.3)Alpha adv H3T and it shutters on take off. Just for the first 2 seconds or so. Front diff is fine. Already did the cross member upgrade bushing. Does this have to do with 40/60 Unlock position on Transfer case? I have searched the google fu with no luck. Tranny full. Done this since I have owned it. Not getting worse, just annoying in my old age.

Buddy said I needed to get the GM t-case fluid and replace it. Somebody please splain dis?

Thanks

Yup...might be the t-case sticking. Mine did this below 5mph on take-off and stopping. At 40k miles the fluid was nasty. Eventually..It totally let go so I replaced the entire unit with a new one. Now I change fluid every 20k.

Lots of opinions on the correct fluid. If you have doubts just get the GM sauce. The part number is in your manual (differs depending on year)....Amazon is half the price of the dealer.

Thank you for the response. Was that a 4-1 case as well that you experienced this?
