Q: how can a transfer case loose oil on 2002 Chevrolet Silverado 2500 HD

What would make a transfer case loose fluid? I had it checked and guaranteed by a local business before taking a road trip, they said it was fine. Broke down 200 miles from home where a local mechanic said it had no fluid in it. Sounds fishy??? How do you loose fluid in a transfer case in less than 2 weeks? Help please.

Check your transmission fluid level. I have seen cases of transfer case seal failure that seeps into and fills (overfills) the transmission. It is difficult to diagnose, in fact, the only way is to monitor both fluid levels.
Check transfer case for small pin hole on passenger side toward the top. Pump in transfer case gets loose and rattles and wears a small hole in the case. Will not leave puddle on the ground. will only leak when truck is going down the road and it will mist the fluid and show no signs on the bottom of the truck. Chevrolet redesigned the back half of the transfer case housing and it costs about 400 dollars for the part. Unless you need the chain too. You can do this yourself with minimal tools, all you have to do is pull rear driveshaft and remove back half of the case. Hope this helps.
