See attached .hpt file. My OS is 12212156.
I have a 2002 Silverado truck engine and a 1994 4L80E trans from a Suburban and would like to run this transmission with the correct tune rather than using the 4l60E tune that is in my VCM. I believe I need to find the 4L80E file first, than email it to Bill with my .hpt file. Is this correct? Thanks in advance!
