Hey guys,

thanks for helping me out with your information about the HP tuner for the 4L65 to 4L85 swap.

I know this is a 8 yr. old thread but its still a good topic and if anyone knows anything about the difficulty involved in swapping a 4L65E with a 6 speed 6L90E please let me know. My 4L65E is starting to overheat at highway and if I have to replace it really want to go with a 6 Speed with my 6.0L
