Hi,
I am in Australia and have been blessed with a good old American truck to work on.
The transmission went into limp mode and does not shift gears.
I have replaced the complete wiring harness for other reasons
I have replaced the NPBU switch and internal wiring harness
I have also just replaced the TCM
I am looking for a standard tune file to write to the TCM to make it work again.
Due to the lack of these trucks here our Holden dealers aren't even interested in
giving the programming a go.
So is it possible to just write entire a standard tune file to the TCM?
Is there any other information I need to supply or will any 09 Silverado 6.6 Auto tune file do?
Thanks in advance
Brad
