I have a 1999 silverado I was leaking transfer case fluid.
After the mechanic replaced the seal a few weeks later I tried to use the
4wheel drive. It didn't work. Last week I took the truck in to the mechanic
because the 4wheel drive wasn't working yet. After they checked it they told
me the cluches in the transfer case were burnt out. How could I tell if they
put in the wrong fluid?
Which seal did the mechanic replace? Was the t/case
low on fluid before you had the leak fixed? Was the
4x4 working before the leak...or had you not used
it for a while?
The fluid should be blue. Even if the
mechanic had put red ATF in the t/case,
I can't see it burning up the clutch pack that
quickly. They did use ATF for some of the
clutched t/cases in the early years of the
Even with the correct fluid, we overhaul
these t/cases on a regular basis. Often the
clutch pack burning up is the result of
problems in the front differential.
