2009 duramax tcm tuning

[Cougar281]

It was for the A41 & A46 TCM's, not the A50 which is the 2009+

Where would we find an A41 or A46?

Not quite as exciting as you might have hoped I'm afraid.

Makes no difference to me, I have a 2005.

I was just curious about clarification on what the "6-speed TCM additional support" meant..

I have no idea, I just had files sent through.
However, when you use TIS2WEB now and you have to select the TCM part number from the list apparently they are in there.

Whats the word on the 09+ TCM's anyways are they going to be supported?

From the start of this thread......

Not yet. Part of our Black Box Logging / Reading update is to test some new methods of reading the entire flash memory of 2006 - 2009 Allison TCM.
Tuning the 2009 TCM probably won't happen until late 2009.

These days should read mid to late 2010, sorry.

I wonder if anyone has tried plugging an 07.5-08 TCM into an 09+ truck.

[rcr1978]

I've got both a 07.5 and 2010 sitting here but not the balls to do it . Whats the worst that could happen the 2010's mine but the 07.5 my works. How much can a new TCM be had for anyways just in case?

[GMPX]

Double check then check again the TCM pin outs, replacing a burnt wiring loom won't be fun.

[rcr1978]

Does anyone want to share a schematic of the TCM wiring for both years of these trucks? 07.5 & 2010

Thanks

Can I beg, bribe, or otherwise polute the priority list to get this one to the top???

Problem is with the twin turbo trucks we can't get the converter to lock-up every time. Very annoying...

You guys Rock by the way
