Hello. I have a 2021 Chevrolet Colorado 2.8 liter and may need to modify my transmission calibration. Can I do this using my MPVI? I purchased this years ago for use with my 1998 Grand Prix and have used it to read my old 2016 Colorado 2.8 liter. It seems like this interface will not read my 2021
This vehicle has been to the dealer multiple times for a transmission shutter from 1st to 2nd when pulling my boat. I just wanted to compare the trans values for my old 2016 vs this 2021 as it seems the transmission has been lazy since I bought the truck (with 23 miles on the odometer). I'm not posting a transmission question here, just an ecu/interface question.
