C1500 or K1500 ,2wd or 4wd/
THE TRANSMISSION MUST BE EXACTLY THE SAME OR PCM MUST BE REPROGRAMMED
4l80 IS CLASS SERIES OF BOX.
NOT EXACT, EVER. MANY VERSIONS ARE MADE OF THAT SERIES. FOR ALL GM VEH..
even special gear ratios and 4wd /2wd differences
only ford can answer that and to get any valid answer
the alien box 2500 transmission tag must be told to ford.
or go to a tranny shop ask them for a look up
tag or photo the tag in hand.
or get the RPO list for both trucks
see Mxx numbers for tranny.
the 2500 uses at least 6 versions. of box. tranny codes IDs. M30 or MT1 and 4 engines
you do know each engine opted day one the gear ratios can be different. right?
the shop manual on the box shows huge table of variant for series 4L80
the codes are called by GM model codes.
(sub codes those are)_
the OSHD I THINK IS THAT CODE.(random gm 4L60/80 codehere)
I say read your C1500 RPO list see if it is M30 box
and buy , that box and model code matched.
know this too, GM will not have PCM programming for boxed not sold day1 new that C1500/
but do ask them. vast transmission exist for just 1 series.
