hey mike in a 2011 gmc sierra 5.3 i believe the trans is the 6l80 correct?
what would you do to the trans if this was your truck and it was bone stock.

gasser prevenative maintenance

- Start date
It's probably a 6l60e if its 09+
The 6l80e is in 2500/3500 gas trucks
If you are asking about upgrades, I would probably leave the trans alone if the rest of the truck is stock.

The trans should be in the 6L family. Not much you can do to it at this point. Transgo will not support this trans as of now. Electronic tuning may be a possability to raise line pressure.
i'm 99% sure its a 6l80
this truck will be staying stock so i'm not worried but i trust your experience more than a warrantee
