Hello there! How are you doing?
So I changed the transmission hoping to get it working just by changing the VIN... did not work... so after a lot of reading I discovered that I need to find a compatible OS. Either on Chevrolet TIS or a set of Efilive files.
Does anybody have the pair for this combo? Could not find it on the dropbox. I attached the read of the current ECM and TCM modules.
Thanks!E38.ctzT43.ctz
