fnlyfnd Posted February 23, 2006 Share Posted February 23, 2006 I saw on nasioc that overfilling your gear oil can cause grinding. I had a 2nd and 3rd grind. I used mt90 and 1qt syncromesh when I changed the oil about 1.5months ago. It seems that the gears are grinding more and more everyday, although the first week was pretty good (which was like spring warmth). I suppose it could be due to the cold weather, but I thought the new oil would be alright in cold weather. I did overfill the tranny a lil, so whats the verdict? I am sick of this grinding. My reverse grind went away for a lil while also, but that is back just like before. Link to comment Share on other sites More sharing options...
stevecd Posted February 23, 2006 Share Posted February 23, 2006 I wouldn't personally overfill the tranny since they give a big warning in the manual, but I doubt that is the problem also what I would do is try the seafoam that is made for trannys and see if it does anything from what I heard it does wonders. Good luck Link to comment Share on other sites More sharing options...
Strakes Posted February 23, 2006 Share Posted February 23, 2006 Um, have you tried taking some oil out? I have had success with a $4 hand pump that goes onto gear oil bottles, but using it with the suction-hose stuffed into the dipstick hole and pumping some out to get the level right. And if this doesn't work, search nasioc for Uncle Scotty's Cocktail....it's very nice. Link to comment Share on other sites More sharing options...
fnlyfnd Posted February 23, 2006 Author Share Posted February 23, 2006 I didn't try to tak any out since its been cold and wet. I only overfilled by maybe .1 or .2 of a qt. I am either going to try uncle scottys mix or this other stuff BG Syncro shift. 2 wrxers are using it and they love it, they dont have any grinds and can get into 1st now w/o coming to a complete stop. http://www.slowboyracing.com/shop.php?sid=PHPSESSID=fe9684c73e8a0b1df64fe9efd3f8e178&cat=883&PHPSESSID=fe9684c73e8a0b1df64fe9efd3f8e178 Link to comment Share on other sites More sharing options...
DerFahrer Posted February 23, 2006 Share Posted February 23, 2006 .1 or .2 quarts I wouldn't really worry about. A quart overfilled, yeah, definitely a problem. But that's not enough to make a difference. You used Redline MT-90? I tried Redline 75W90NS and it made my 4th gear grind whenever I tried to engage it, cold or hot. But it shouldn't grind on MT-90. That's a GL4 oil. Link to comment Share on other sites More sharing options...
fnlyfnd Posted February 23, 2006 Author Share Posted February 23, 2006 yea mt90 and syncromesh....I think it might just be the cold weather causing this. Today it reached 40 and driving around all day it only grinded 3rd once. This was within the first minute of driving. After the car warmed up it was really smooth, so....
