Title: T-case
Post by: nilock10 on February 21, 2003, 07:01:00 pm

i have an '81 K10 with the np205, for some reason when i put it in four-low olny the rear tires spin. they all spin in four-high so i thought that maybe the T-case needed to be rebuilt but im not sure. i don't no alot about t-cases so i way wondering if it was soposed to do that or if there was some thin wrong with my t-case. if it is soposed to be like that is ther a t-case that spins all four tires in four low.

If only two wheels are spinning, then you should be in 2WD. I'm pretty sure the NP205 is a part-time 4WD t-case, so the t-case shifter might be worn or something, and you may be putting it into 2WD instead of 4WD low.

all of the other gears work. 4hi and 2hi. i put the stifter all the way forward and the engine revs high so i no its in a low gear but olny the back tires spin.
