Black Transmission Fluid - - Any Hope???
Hey all, My wife and I just got hitched and I've now inherited the responsibility of maintaining her little 2002 Toyota Rav4... her pride and joy. I've been taking it in for its regular oil changes for a while now and decided to check on the transmission fluid the other day... turns out it's never been changed. Ever. The car now has over 120K miles and has no super-major transmission concerns "yet," but the tranny fluid is, of course, about as black as it gets. I was about to have the fluid and filter changed out but the mechanic said that once it gets that dark it's better to leave it in and start saving for a new tranny. He explained that the sediment in the fluid, if drained, would settle into the transmission's inner parts and more than likely ruin it right away. Does anyone have any experience with something like this? Is it possible to save this tranny? Is this an exaggeration? Thanks in advance for your help and shared knowledge! :smokin: -- decoyfred ------------------------------------------------------------------------ decoyfred's Profile: http://www.automotiveforums.com/vbul...?userid=195227 View this thread: http://www.automotiveforums.com/vbul...d.php?t=697747 http://www.automotiveforums.com |

Lots of people, however, don't give transmission service a second thought until it is late in the game. We've heard the story that, in transmission like this, it may be inadvisable to service the tranny at this stage. The claim is that sludge and varnish are the only reasons your tranny continues to work and if you clean it up, it may fail. (Whether true or not....) The previous mechanic's story is, however, a little lacking in credibility: If the fluid is black, you are already circulating crap through the innards. If you drop the pan and clean it out, you will not stir up any new 'sludge'. In my estimation, you are already driving with a ticking time bomb. It WILL fail, sooner or later. I would prefer that my car fail at home than on the road, but I never let my cars go so long without service. If it were mine, I would be sure I had money reserved for a rebuild, and would change the fluid. It is your choice, and your gamble. Nobody can tell you, for sure, what is going to happen. |

If it smells burnt or like burnt toast, it is likely in trouble. Otherwise I have seen a bunch of really black fluid come out of a lot of old vehicles without them failing soon after. Lots actually.... I have even seen what looked like diarrhea come out of a couple Jeep CJ ones that got filled with muddy water and they still ran after too. However, I also hear of a lot that go to quick lubs and get told what you are told and do it with 'them' anyway. Those ones for some strange reason all seem 'to' fail....

I have been to one of those quick lube places before.I will never go to
one of them ever again.One hot afternoon,I didn't feel like changing the oil and oil filter and lubebing all of the alemites,(1978 Dodge van) so I drove my old van to a quick lube place.I told them all I want for my old van is an oil and oil filter change and a lube job.I was standing there at the front of the lube pit and watching as best as I could.I don't think the guy lubed all of the alemites.When I got back home and I looked under my van,I could see most of the alemites haden't even been touched,so I got out my grease gun and I lubed them all myself. cuhulin |

If changing the fluid causes the transmission to fail, it was bound to leave you stranded sometime soon anyhow. I would have the pan dropped and cleaned out, filter changed, and transmission fluid flushed. A transmission shop would be better than a lube place to take care of this, but I'd call both and compare pricing. I'd let a lube shop do a transmission flush as long as I could watch the whole proceedure... It's actually pretty simple to do. Before doing anything, I'd check the owners manual to see if your vehicle needs any special type of ATF fluid. |

Thank you all for your replies. Anyone have any particular transmission shop in South Fla. they'd recommend? I think there's probably no sense in perpetuating the neglect. A good transmission shop might have that magic touch our little car needs.

Back in the days of American 3-speed automatics, you could run them over 200k on the factory fluid with no damage. Its true that modern 4- 5- and 6-speed transmissions are far more fragile and should have more frequent fluid changes, but 120k really isn't excessive since most manufacturers still only recommend 60k intervals even for severe usage. My guess is that the transmission has been slipping and has burned the fluid due to a mechanical problem. When you say "no super-major transmission concerns" it leads me to think there is SOME transmission behavior that you're noticing is "not right." Sorry to say, its PROBABLY dead. But not necessarily... I was about to have the fluid and filter changed out but the > mechanic said that once it gets that dark it's better to leave it in > and start saving for a new tranny. I do NOT agree with that philosophy at all. Yes, there are conditions where doing a fluid change will cause a transmission that is marginal to start slipping- but IF a fluid change does that, the transmission was NOT SAFE to continue driving anyhow. Change the fluid and filter- if the transmission works it will work a lot longer than it would have with burned up fluid. If it quits, then it was about to strand you somewhere anyhow. Oh, and BE SURE to use only the factory recommended fluid type. |
