Need a 2008 Denali 6L80 base file for a New Monster Trans

Does anyone have a TCM file for a 2008 Denali? We bought a 6L80 from Monster Transmission and they didnt load anything on the TCM. When asked they said they dont do that. Not sure how theyre selling transmissions to people that cant be used without a trip to the dealer or in my case buying a bench harness to load a file with HP tuners.

It is still a AWD setup and its in a 90 Chevy truck with a supercharged 408. Were running a terminator x max. Holley doesnt have any way to load a TCM file.

Yukon Denali
Yukon XL Denali
Yukon Denali Hybrid
Sierra Denali
Envoy Denali
Envoy XL Denali
Acadia Denali
Terrain Denali
Canyon Denali

DENALI IS A TRIM LEVEL, NOT A VEHICLE.

Your going to need to find someone with a TIS and a way to load a GM calibration into the TCM.
HPT cant load the whole tune into a new TCM.

Monster transmissions leave much to be desired.
Hope you dont have to fool with their customer service when transmission craps out.

Their reply when I asked why the trans doesn?t have a base file in it pretty much told me all I needed to know.

I got lucky, and the "new" TCM in my 6l90e had firmware, but no tune. I was able to tune it with HP tuners using the factory tune I took out of the truck, and then modify it too my liking.


I actually tried to buy a monster, before I found the local shop I used. They held my money for 4 months always promising to ship "in a few weeks". Then when I finally had enough it took them 3 weeks to refund me, but not without a restocking fee because "we built it for you!".
So I ended up with $900 in store credit I had no use for.

Dirty bastards.


If the local shop was open fridays, I'd have never used monster. Now, I know why they have such a shit reputation everywhere.
