The 241c manual t case has 28 spline planetary you will need 32 for nv4500 what I did was took the planetary gear from a push button transfer case with a 32 spline and put it in my 241c manual transfer case and it bolted right up
I'm having trouble with wires I have a 1992 k2500 4x4 that had a 6.2 with 700r4 in it, currently has a 5.7 with nv4500 my question is whatdo I do with the four prong electronic from the ecm
