Hopefully someone can help me out with a programming issue we are having with a 6L90e auto from a Chevrolet Express fitted with a Duramax.
We are running this auto standalone with an aftermarket controller in a Toyota - the standalone setup seems to work fine.
The issue we are having is we have purchased some brand new autos from GM (part number 24256185) and they come with no program in the TCM.
We have the GM MDI unit which lets us plug into the auto to program it but it requires a VIN to load the appropriate program.
We have found a few VINs for the Express with a 6.6 and 6 speed but the VIN has to match the model of auto for it all to work.
Mr GM said they can't help us.
Does anyone know how to get around the VIN issue or how we can work out what VIN will allow us to program these autos?
Any help would be awesome
Thanks Elliot
