Markbo Posted November 19, 2014 Share Posted November 19, 2014 I swapped out an O2 sensor today and have time so thought I would install a new A/M TMIC I bought... many months ago. I have had a code for bank 1 lean. When I was doing the removal I found this: http://i116.photobucket.com/albums/o10/Markbo_photos/Auto/DSCF8569b_zpsccd79de0.jpg The white clip holds 2 vacuum lines coming up from the tranny. Nothing is connected to it. That seems very odd to me. What is supposed to be connected to it? Surely they don't just dead end open there huh?

MrTris Posted November 19, 2014 Share Posted November 19, 2014 Do you have a 5EAT? If so, there are vac lines on the top of the trans that do in fact, terminate to nowhere. Link to comment Share on other sites More sharing options...
Markbo Posted November 19, 2014 Author Share Posted November 19, 2014 Yup... 5EAT. I have never in my life seen vacuum lines that terminate to open air. That is just weird Subaru, weird! Link to comment Share on other sites More sharing options...

MrTris Posted November 19, 2014 Share Posted November 19, 2014 Yup... 5EAT. I have never in my life seen vacuum lines that terminate to open air. That is just weird Subaru, weird! I know it. At first I questioned it when I put everything back together, but, that's what it is - Link to comment Share on other sites More sharing options...
covertrussian Posted November 20, 2014 Share Posted November 20, 2014 Transmission vent tubes, my non Subaru manuals have always had them too. 23 WRX - Stock / De-Crosstreked 05 LGT 16G 14psi 290whp/30mpg (SOLD) / 12 OBP Stock 130whp/27mpg@87 Oct / 00 G20t GT28r 10psi 250whp/36mpg Link to comment Share on other sites More sharing options...
boxman Posted November 20, 2014 Share Posted November 20, 2014 Transmission vent tubes, my non Subaru manuals have always had them too. I'd guess one for center diff and one for transmission. Breather tubes are common on diffs, t-cases and transmissions...the fluids expand when they heat up, gotta account for that somehow... Link to comment Share on other sites More sharing options...

Piggylover1985 Posted November 21, 2014 Share Posted November 21, 2014 Yup... 5EAT. I have never in my life seen vacuum lines that terminate to open air. That is just weird Subaru, weird! All automatic transmissions have vent tube to let the air out from moving parts. I have seen people plugged them off ( don't ask why) and the fluid came out of the filler tube Link to comment Share on other sites More sharing options...
Markbo Posted November 21, 2014 Author Share Posted November 21, 2014 I have seen lots of vent tubes on different cars. Never seen anything like these. Still look weird. Then again I have only been "working" on this car a short time. The little woman just drove it & put gas in it for 9 years first. She is still surprised I want to drive 'the little car'... It's funner now than it was, that's for sure. Link to comment Share on other sites More sharing options...
