Been out of the game for awhile...last I remember (4 years ago) there was a company working on a standalone controller for the 6L80E. Did anything ever come of that, and has anyone figured out how to run a 6 spd trans in a GMT800?

...and as a followup question, has anyone set up a GMT800 to run on a newer GMT900 CAN bus ECM/TCM system?

....and on top of that, if there was a way, would it even be worth the expense?

In for the info about the 6l80 also.

Smokeshow has a E38 ECU swap in his truck but he is running a 4L80E.

As for the 6L80E I believe you would need to do a similar swap to make it work in the GMT800 trucks.

1FastBrick thats only way to go so far. I'm working on my own standalone E38 wire harness for the 67 Chevy truck.

His isn't stand alone though. It works like it was factory in his GMT800 Series truck. He even wired it up so the AC works correctly.

I don't think it would be worth the expense. It took me over 2 weeks working every day to do the research and actual wiring to get the truck running on a GMLAN system...it just isn't cost effective. Like many of my experimental projects lol.

It would be simpler, however, to have a standalone passthrough controller for the 6L80e internal transmission computer yet have the truck still operate on a class 2 data bus. But nobody currently offers anything like that as far as I know.

there is your million dollar idea!!!


Hey, it might not be cost effective but it's got the cool factor...

Besides, it's more about the journey then the destination with this hobby!

It's called a TCM-2650 Mechatronic made by Powertrain Control Solutions. I have talked to them about it and guys have done the swap in gmt800 trucks. It will be standalone and that includes if you want tap shift and a shift indicator of some kind. I might do a 6L90e on my 04 when I blow the 4L80e apart... but we shall see.
