Find a 2019 vehicle application that uses the 6l90 and either L83 or better yet the L86. You'll need at least a 2017 or newer OS or change the fuel pressure sensor out for the 2016 and older style.
I'm not sure if you will be able to use the older but not factory locked T87 TCM in place of locked T87A TCM that you would have now.
Most likely it will work, but would have to be tested.
What is your "2019 L86 with 10L80" vehicle type? Is that an Escalade or Yukon?
If so, you might be able to take a factory calibration from a 2019 Silverado Classic with an L83, make it work with an L86, then modify your engine and transmission harness to connect up a 6L90.
I also have a question about going from the 8L90e in a 2016 escalade to 10L80/10L90 i'm not sure if anyone on here has done it I have bought T87A Part#24279973 for a 2018 escalade I just need to source the 10 speed and the connector just wondering if anyone has any experience trying this, I have searched and haven't found much information on it I have all wiring diagrams my just wondering if anyone has successfully did a swap similar
I am in the same boat as you and most likely went farther with this than anyone else, haven't continued the project in over a year if not more.. im going to dive back Into this, dm me for Info.Quote:
