Trans swap from 2010 to Chevy performance trans
Working on my 2010 silverado and trying to find some answers. The stock 4l60e transmission went out on me and I picked up a new Chevy Performance 4l70e. The part number of the new transmission is 19260961 and it has a 15 pin connector going into the trans. The Chevy catalog says to use 19257634 trans controller. Doing some searching on the forum I see that in 09 chevy changed some things on the 4l60e and it has a 17 pin connector. Is it as simple as flashing in a 07-08 tcm tune, do I need to repin the connector, I saw that some things like the gear indicator is now internal... I have a tuner but I guess I'm not explaining it right to them and its at a buddies uncles house. I just want to make sure I can drive it when the new trans is in.
