Tranny flushing experience

 Hi all,

 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 radiator hose

 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. Second, thanks
 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 oil.

 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 marker on
 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.
