Look at your PRO code sticker in your glove box and if the PRO code is:
M30 = 4L60E.
M32 = 4L65E.
M33 = 4L60-E,ELECTRONIC,HYBRID A/TRANS
MT1 = 4L80E

Good luck and hope this helps.

No, the only Allison is with the Duramax diesel. The only other gas engine to ever have an Allison as an option was the 8.1L which has been discontinued for several years
