NP208 transfer case question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys

I have a 86 K10, with the 208 transfer case

I can switch from 2HI, to 4HI all day no problem. When I put the truck in neutra/parkl to put it in 4LO, as soon as I hit N (neutral) I hear gears grinding, and I can't go into 4lLO, or back to 4HI.......it has fresh fluid in it, and it is topped up. I end up turning the motor off, and stoping the gears from moving, to change it back

Am I doing something wrong?, or is something screwed in the TC?. I don't usually need 4LO, but I want it to work, just in case I do need it

Thanks
Cameron

It should not be grinding. That usually means bad things. I know on my K-5 Blazer with the 208 its hard to get it into the 4Lo and hard to come out but it defiantly does not grind.

My 86 K5 does the same thing when i try to shift into 4lo. Some times if i put the transmission in neutral and throw the 208 in to 4lo real fast it will go right in no grinding. I haven't had my k5 for very long so i don't know if it is normal for a 208 to do that or not. I doubt it is but it works fine once i get mine into 4lo its just a real pain in the butt.

Sounds like the plastics pads that sit over the shift fork have worn out inside the case

How hard is it to replace those? I can't seem to find much info on the np208 in my chilton book.
