Transfer case

Hi everyone!

I have a 1988 K2500 with the 6,2 diesel and hillbilly 3 spd manual tranny (actually L-1-2-3). As far as i know, the K trucks from around -87-88 have the NP241 transfercase and the earlier with 4wd had the NP205 for part-time 4wd and the NP203 for full time 4wd. Am I correct? And does the 205 and 203 interchange with my 241? I think they should cause the main tranny and the frame mounting points haven´t changed since earlier years, have they? Maybe someone of you guys know better.

Give Advance Adapters a call. They'll be able to answer all your questions. Your hillbilly 3 speed is actually one of the best manual tranmissions ever put in a light duty truck. The SM465 was first used in 1968 and used in everything from 1/2 ton pick-ups to 2 ton dump trucks. Keep it, any other tranny you would swap in will be a downgrade in strength.
