2008 Silverado with E38 T42 and manual valve body????

[hellbents-10]

Anyone get one to work like this or will it need a manual trans file?

I have torque management kicking in no matter what I do. I can start with stock TM settings all the way to having every single thing maxxed out one by one with no luck. I would rather keep the truck controller so everything works as it should. Normally this would be a swap vehicle and it would be no big deal to throw a pedal and manual OS in it.

It seems as though there is some missing parameters in HPT with the E38-T42 combo to get past this.

Oh it is a reverse manual valve body and I have even matched the gear ratios to the gear selection with no luck.

Here is my latest hail marry attempt with no luck.

It is odd sometimes I can fire it up and it will have no TM and run great. Shut it down and restart and right back into it trans TM even in neutral.

The problem is I need to keep the truck cal as it is in a 2008 silverado. So I need to keep everything functional in the stock truck. If this was a swap it would be easy.
