this has prob been asked before but i couldnt find it i have a 2000 gmc jimmy with auto 4x4 the encoder motor went out on it and i dont know which one i have to get the proper one for it it has the auto 4x4 so im thinking it has the motor with the 7 prong plug on it but im not sure does anyone know which one these vehicles have ?

 

If by Auto 4 WD you mean the 4 button unit (4Hi,4Lo,2Hi,4Auto), you need the Motor for that switch unit. Normally a New Venture Gear 136/236/246 Transfer Case; w/RPO Code NP8; Square Plug w/4 Pins & Rectangular Plug w/6 Pins.

Check your glove box for the proper Code: NP8 or NP2.

 

awesome thanks man ill look today when i get home to see which one it is cause im suppose to go get the new one today for it and hopefully be able to drive it again lol thanks again

ok well the sticker has been scratched off from the glove box is there another way to check and see which encoder motor it has on it

 

If you have 4 buttons on the 4wd switch in the dash (Auto, 2HI, 4HI, & 4LO), then you have the NV236 transfer case.

As far as determining what encoder motor you have and the number of connectors and pins, it is under your truck. Park in the grass somewhere dry and crawl underneath. It should be pretty apparent.

 

i have done that got the old one off has a 6 pin that plugs into the side and then a four pin rectangle plug but im hearing there are two kinds unless the other one has diff pins and where im gettin mine they have not a clue wat they doin

 

You need one that matches what you have. There is only one that has the 6pin & 4pin connectors on it. The other designs are for other transfer cases.

The NV136 has a single 2pin plug. The NV233 typically has the 7pin plug.

 

ok cool your a lifesaver man now i can my wife off my back lol i as juss wanting to make sure before i went and bought it this afternoon


ok well i got the new one and put it on yesterday still to no avail doesnt work so now im stuck wont go into 4x4 at all when you push the 4 hi button all it does is blink and wont go back into 2 hi i can hear wat sounds like the encoder motor working to try to move the selector in the xfer case but theres nothing happening on the dash and i can hear the comp clicking behind the kickpanel tryin to switch it but still nothing any sugestions
