95 4x4 Blazer with automatic transmission:
Had tranny rebilt last year. Ever since I need to occasionally add some
ATF, but none showing up on floor as leak.
Today, while looking for vacuum problem (no reserve vac-AC flaps close when
engine under load), I found nearly 4 ounces of ATF in that little round
ball vac resevoir that is mounted on the hood, drivers side.
The vac line runs from manifold over to drivers side to a check valve where
it splits: one leg goes to vac resevoir and the other goes to a T and two
small vac lines that disappear into lower area of engine compartment
dashboard. I know one of those legs handles the climate control/heater
The question is, of course, how the hell is ATF getting up into the vac
resevoir?!?! Could a vac line have been hooked up incorrectly when the
tranny was replaced? Where should I look and what should I look for?
Also think that the 4wd is not kicking in. Could that be part of the
problem or a result of something being hooked up wrong?
I have no vac diagram to work from, so any help the more experienced can
provide the better.
Thanks for any direction you can provide.
