Why are you trying to retro a 1995 4L80E into your 1992 C2500?
Asking as the 91-92s had a diff valve body, EPC harness and command and control framework compared to the 94+....1991-1993 are considered interchangeable whereas 1994 is a stand alone year for those units; 1995-1996 are interchangeable as are 1997-2013. The selector shafts are longer as well starting in 1995, and I believe they introduced the shift cable that year also so not sure it would work "as-is" with your external mechanical shift linkage on the 1992 truck.
because my revers band broke, and i found this 95. and in norway 4l80e's from a rwd is not commond. and i need to use the truck while i rebuild my old one. Okay, but when i search on the valve body, it says 92-96, so aren't they the same? i know the 91 has the screw in temp sensor. but that was a one year only.
