can someone point me in the right direction as to what needs to be done to go from a 05 4L80e to a Fbody T56?
Its in the vehicle (GT mustang with 6.0) and the original harness being used is the 05 truck harness that had a 4L80e.
Would like to get the VSS set up to help with some idle issues coming to a stop.
thanks!

 

There is some wiring tips in this thread: https://www.performancetrucks.net/fo...thread-381877/

You'll have to sift through it, there was a crappy diagram somewhere. Might be of some use. I will be dealing with this too soon, 60E to T56.
