Title: np203 shift pattern
Post by: derrick79 on December 23, 2009, 01:38:54 pm

i have been doing some reading on this God awful transfer case. i think i understand the shift pattern on it but im assuming my 76 has the part time kit in it. it has manual hubs on the front and with the hubs disengaged my back tires spin and with them engaged all 4's have traction. ANYWAY does anyone know the best position for driving in 2wd and which ones i should use for something like 4hi and 4lo.
thanks

If it's been converted 2Hi works fine. 4Hi for 4wd action. 4Low for gear reduction Low loc for strictly off road gear reduction.

There was a thread on this recently
