I just wanted to pass along my experience flushing my tranny fluid
this morning. I used the modified bay 13/volvo method of using the top
First, I couldn't believe how *nasty* the tranny fluid was that
pumped out. It looked like brownish black sludge. Wow- my car has 75K miles.
to all of you who have posted instruction and hints for this. It was *much* easier than I thought, pretty much as easy as changing the motor oil, without
having to get under the car. I flushed 18 quarts through just to make sure it was really clean when I was done. I am *so glad* I didn't pay a dealer $140 to do
For those of you who have been putting this off like I was because
you were a bit intimidated, flush your tranny now! What I saw come out
of my car couldn't
have been good for it.
I also changed my flame trap yesterday, per the bay 13 intructions.
Mine was almost totally clogged with junk, and I had started to notice
some oil spattering
from crankcase pressure. Again, I'm glad I gave it a shot, it wasn't that hard.
Thanks again, everybody- this is still a great resource. And thanks
to the guy with the OZ website for pulling down some of the discussions
on this board
and archiving them- it's very helpful.
CAUTION ! When you run your engine to pump out the tranny fluid
DO NOT let the pump run dry. High pressure pumps DO NOT run well without
My solution to that problem was to take an old drywall bucket,
and using a liquid measure from the kitchen and some water, mark with permanent
the inside of the bucket marks at 2,4,6,8,10 and 12 quarts.
When I was flushing the tranny I would just turn the engine off
each time I reached the next mark, and then added 2 quarts of fresh fluid.
That way I didn't
have to watch for the air bubbles in the fluid getting pumped out. This seemed to work just fine, and felt very safe as far as running the tranny dry.
Happy to have helped, Wes. My ATF looked much worse once out than what could be seen when looking at the dipstick. That was at about 57000 kms.
Monitoring tranny atf output levels is a great idea to safeguard
the flushing process. It would probably still be a good idea to watch out
for air at the output, I
think. I have been looking at TSBs today on auto transaxle maintenance/recon, and there is an awful lot that can go wrong in there. Monitoring of all vital
signs during the operation couldn't hurt.
