Is it possible to swap a 4l80e out of a 1999 k2500 4x4 into my 1995 k3500 4x4? If so what will I need to change? Thanks

Yep, that's it. You used to be able to buy the adapters pre made. Just make CERTAIN to use the correct trans fittings in the correct spot on the 99. One of the fittings is long(99% certain it's the rear one), and it will run dry on oil if you install the wrong fitting as it will dump the oil back to the pan instead of feeding the lube circuit. Only other thing is 97+ used 3/8" cooler lines vs the 5/16" of 96 and older, but it's not an issue to concern yourself with.Its a 4l80e to 4l80e I was told by some its just an cooler line adapter I need and others say its not possible. Hopefully @THEFERMANATOR can clarify
