What's involved/changed during a transmission tune?? I just recently completed a 4L60E swap to replace the TH400 behind my H/C/I LQ4. I put a trans tune file that I found on HP Tuner Repository on my existing tune file.
I am trying to figure out what exactly will be changed from a factory 4L60E to a built stage 3 or 4 4L60E tune. I feel like mine is running a little hot compared to the TH400 tranny. Any help would be great!

Yes, the stall is a 10" Transmission Specialties 4000rpm Lockup converter. I previously had a non lockup 4400 stall vigilante behind the TH400. I'll take a look at what my tranny's settings are at.
The TH400 used to run 150-180 degrees and the 4L60E is running 180-220ish. I have my sending unit for the gauge in the test port on the 4L60E so I know its reading 10-20 degrees hotter. I had it in the same spot on the TH400.
