Scion grinding in 2nd or 3rd? This is what you need!
Wow, I am shocked! So I've been dealing with my gears grinding in 2nd and 3rd for the past 1 1/2 Years in my manual 2005 Scion XA the car has had the problem since before i bought it, The previous owners replaced the clutch, And I'm assuming that someone had added extra gear oil, Because it spilled out when i took off the fill cap on ramps, I've been trying to figure out the grinding, For the past 2 years doing everything but trying to put a new clutch in, Previous owners also stated that the mechanic may have put the clutch in wrong, I guess he didn't, Because this nearly completely fixed the issue in under 200 miles of driving, Driving has also become much smoother, If you have a Scion XA i suggest changing to this oil regardless if your gears are grinding! You only need exactly 2 quarts for the Scion XA no more no less, I wish all m mechanics would look this up before adding too much oil! I found this out from reading forms on the Scion XA, Everyone suggested this oil for the grinding and regardless! So i hope someone sees it here!

Seems to be a very good oem alternate
My 2007 Corolla 5 speed always had a “notchy” first gear engagement when coming to a stop and this was immediately gone when switching to this fluid. Keep in mind when i drained my transmission the old fluid smelled like it was at the end of its life and i have no idea which fluid was in it before as I’ve only put about 15k miles on the car in over a year and a half. Overall I’m very happy with this fluid and it seemed to make shifting overall more smooth. Would recommend
