ScoopMan Posted March 10, 2010 Share Posted March 10, 2010 So it was shifting poorly, so I checked the level and the stick was dry. I added 75W90 about a cup at a time, and checked the level each time. Or so I thought.... Hard to read the stick when the oil is so clean. Ended up putting in about 3 cups, or about 3/4 quart. Then I checked it, and level is about 1/4" above the top 'F' hole. How bad is this? Should I pull out some oil or not worry about it? Link to comment Share on other sites More sharing options...
ClimberDHexMods Posted March 10, 2010 Share Posted March 10, 2010 Nothing to worry about... Can you imagine how many cars would be damaged a time after leaving their quick service maintenance garages if it was a problem?

ClimberDHexMods Posted March 10, 2010 Share Posted March 10, 2010 Btw keep checking the level every time you get gas. Leaks don't plug themselves. It just might lower the fluid level by itself eventually. [CENTER][B][I] Front Limited Slip Racing Differentials for the 5EAT now available for $1895 shipped, please inquire for details!

Chocoholic005 Posted March 11, 2010 Share Posted March 11, 2010 The manual transmission in Legacy's depend on the gears slinging oil to lubricate the transmission so a little extra gear oil will not hurt anything. As long as you do not completely submerge the gears (which you did not) you'll be fine. Link to comment Share on other sites More sharing options...
nekdut Posted March 23, 2010 Share Posted March 23, 2010 At what point would it be too much? 1/2" over the F? More? Link to comment Share on other sites More sharing options...
NSFW Posted March 23, 2010 Share Posted March 23, 2010 What happens if you submerge the gears? Link to comment Share on other sites More sharing options...
nekdut Posted March 23, 2010 Share Posted March 23, 2010 Mine is overfilled by about 1/2" according to the dip stick, and a have somewhat of a leak. Is this expected or has a seal gone out somewhere? Link to comment Share on other sites More sharing options...
JoeFromPA Posted March 24, 2010 Share Posted March 24, 2010 IIRC, the system can vent. How long have you had the leak? If it's been awhile, it's most likely a leak. Link to comment Share on other sites More sharing options...
rao Posted March 24, 2010 Share Posted March 24, 2010 The transmission should "use" NO OIL AT ALL. It is not like the engine. The case (like all transmission does have a vent. If the level is going down there is a leak. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
JoeFromPA Posted March 24, 2010 Share Posted March 24, 2010 Rao - Just curious: Have you ever seen a VERY small leak from the vent? I've never seen it in my far fewer experiences, and haven't heard of it on here either. I just understand that the vent is there and that an overfill could potentially pour out of it.

rao Posted March 24, 2010 Share Posted March 24, 2010 Unless you really overfilled it (or used the wrong type of oil ) that isn't going to happen; or if you are a real rally racer and put the car on its roof Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
ScoopMan Posted March 24, 2010 Author Share Posted March 24, 2010 So worst case it seems to me is you might leak some oil out of the vent. I have no idea where the vent is, hopefully not over anything important. Link to comment Share on other sites More sharing options...
rao Posted March 24, 2010 Share Posted March 24, 2010 You are not going to leak oil out of the vent. The vent is located on the top of the transmission. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
ScoopMan Posted March 24, 2010 Author Share Posted March 24, 2010 Pretty logical place to put it So why would submerging the gears be bad? The oil should still be moving around enough, I would think. Perhaps oil flying off the gears circulates and cools better. I dunno... Link to comment Share on other sites More sharing options...
JoeFromPA Posted March 24, 2010 Share Posted March 24, 2010 I'll paraphrase what I've read elsewhere. As the gears are more submerged, more energy is lost in churning the gears through the lube. This results in a bit of lost power, but mainly it generates extra heat in the oil. Which then lessens it's effectiveness as a lubricant that was designed to operate at an ideal temp. Hence, there's an ideal level where energy is kept in the gears (instead of transferred into the oil) while also maximizing lubrication. Link to comment Share on other sites More sharing options...
nekdut Posted March 25, 2010 Share Posted March 25, 2010 So if I have a slow leak, even if it is overfilled, I have an issue somewhere with how the tranny was buttoned back up after the clutch install, correct? Link to comment Share on other sites More sharing options...
rao Posted March 25, 2010 Share Posted March 25, 2010 You have leak. That does not mean that the clutch job caused the leak. Rob IF YOU CARE ABOUT YOUR CAR YOU SHOULD NEVER DRIVE IT Link to comment Share on other sites More sharing options...
