ron2368 Posted August 31, 2003 Share Posted August 31, 2003 I have a 99 Forester, after a 30 minute highway drive with the a/c on I see lots of smoke from the engine compartment . To shorten the story I am very sure it came from 2 little vent hoses on top of the auto transmission . The catalytic converter is just below so it was burning the atf = lots of smoke. I did not notice any shifting problems during the drive. I had the fluid and filter replaced 9 months ago and have not added any atf during that time so it can't be overfilled. Any ideas, other than this time I have never noticed it before. Thank you for any assistance. Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted August 31, 2003 Share Posted August 31, 2003 I don't know if I can help, but others may be able to if you give us some more info. You say it couldn't have been overfilled 9 months ago. Did you look? Also, what is the level now(after the 'burp')? Did you get a CEL or an AT Temp light. Did you check any other fluids to be sure that's where the smoke came from? Carl 1 Lucky Texan Quote Link to comment Share on other sites More sharing options...
ron2368 Posted September 1, 2003 Author Share Posted September 1, 2003 Since the change I have checked the atf and it always was at the proper line. When I looked at the area after the smoking incident I could see a trail of oil residue from below the vents down to the trans area above the converter so I am sure that was the cause. There were 2 drips of trans fluid in the garage below that area also. When I drove home that night( return trip) there was no smoking, also the area under the car is always clean, never any drips, so I am assuming that this never happened before.

1 Lucky Texan Posted September 1, 2003 Share Posted September 1, 2003 Could you or a family member have driven through deep water recently? Here's a WAG - If the tranny gets cooled off by being submerged in deep water, contraction can suck water inside that could vaporize at operating temp causing a 'geyser' like effect - um I GUESS.

ron2368 Posted September 1, 2003 Author Share Posted September 1, 2003 Sorry, no floods not even any heavy rain. The atf was low about a pint. I dont know much more about this problem. Maybe I can get longer hoses and run them into some receptacle so I can see if or how much fluid I am losing.:cornfuzz: Quote Link to comment Share on other sites More sharing options...
