I wonder Why is that NV236 fluid only available at dealers??


Cpt, is that pic the NV236? Front or rear?


For the rerar, I wan gonna go with Mobil, bout how many bottles will I need, 3?

 

Special stuff and GM probably doesn't want to give up the secret to it.


NV233 & NV236 both look similar to the image. It shows the rear of the transfer case.


For the rear differential, 3 quarts will be close, little bit left over.

 

According to owners manual, you should be able to shift from 2HI to 4HI at any speed. Noticed today that unless I'm in Neutral it won't complete the shift.
Crazy but it works and i'm happy..

 

For the encoder motor to perform a mode shift, (at any speed) both drive shafts must be rotating at the same RPM. If all 4 tires are not the same circumference, the drive shafts will not rotate at the same RPM. When the vehicle is stopped, both shafts are rotating at the same RPM, zero

 

Makes sense to me!!
