Transfer case leak?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

myersjeremy · 10-17-2007, 10:05 PM

Got a 85 Silverado 4X4 that loses its tranny fluid and stops pulling but if you let it sit a while and check majority of the fluid is back and it will pull again. What are some things to look for as far as with the transfer case? Is there a way to tell if it is forcing the fluid into the transfer case? Is there an overflow tube because I am getting quite a bit of fluid coating the underside but can't pinpoint the leak. It is definitely not the trans front seal.... Thanks for the help!

I have heard of a leak source being the speedo cable input..duno if that is your issue but thought I would mention it anyway...

Maybe you have the transfer case that runs on tranny fluid?

I am pretty sure the transfer case is the NP203 which uses tranny fluid. I am just thinking maybe the rear trans seal is gone and it is forcing the fluid into the transfer case but I have no way of checking that.

Sorry, I don't know anything about auto trannys or NP203s..other than they are chain drivin.

Sorry....seems it is a NP208....misread the tag. Does it seem realistic that my transmission might still be spared if I figure out it is just the rear seal and the transfer case is overfull? Once it loses enough fluid that it quits pulling I shut it off.
