I just bought a 2012 Sillverado 6.2 6L80 that I've been starting to tune the trans on. A 2015 yukon with a 6L80 just came in the shop. Driving it, you could tell the trans parameters were different. The 2015 was much better shifting. Curious to know if copy in the tune would be safe. Should be the same trans right? Should be able to completely copy the Yukon tune right?
