[net.auto.tech] S10 transfer case

digrazia@nacho.DEC (11/19/85)

Has anyone else experienced difficulties changing from 2-wheel
to 4-wheel drive in an S10?

I find that I can move the selector lever from 2 to 4 easily
only after I've driven the truck for a while.  If I try to
change from 2 to 4 before driving for a while, the lever
stops; it won't move to the 4 position.  It takes between
2 and 30 minutes of driving to free up the mechanism (I
haven't measured it precisely).

I've also noticed that if I set the transfer in neutral,
changing the shift selector (auto transmission), produces
unpleasant grinding.  The dealer's mechanic says this is
normal!  Is it difficult to design synchronization into
these 4-wheel contraptions?

	The Chevy dealership where I used to work had quite a few problems
with S-10 transfer cases .The lucky ones made a grinding noise , the others
turned into gear souffle' when shifted . If I had one of these , and it were
still under warranty (do you know the drivetrain warranty is 24 months or
24000 miles ?) ,I would take it to the dealer and have it checked out.
	Even though they say there is nothing wrong with it ,get it in writing
from the service manager that they checked it and could find no problem . Then 
when it fails out of warranty , you have established that the problem existed
previous to the expiration date . Using this ammo , call the ZONE service 
manager , and ask for GM assistance on the problem . They gave away so many 
hours of labor and transfer cases ,we called them Generous Motors !
	At the time I left GM , there was an intensive investigation into
S-10 transmission and tranfer case problems. Maybe it's under control now.
The service manager should have all bulletins pertaining to factory-approved
fixes .
