I'm Awesome
A 4L80E tune will not work correctly with a 4L60E, but a segment swap is easy and you will not have to license another file.going to attemp crank relearn still before i do anything else, then after that i’ll take it for a drive. what would the trans ratios be for a 60e vs 80e would i just be able to find that online and check and make the adjustments if need be?
