Red Line 50304 MT-90 75W-90 GL-4 Manual Transmission and Transaxle Lubricant (MTL) - 1 Quart (2 Pack)

If you own an old Toyota, use redline in your transmission, it's really that simple. Better, smoother, and longer lasting than anything on the market

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!

I mean does red line really need a review I mean after all it's red line if you know you know

its perfect

For Vintage transmissions such as the 1991 Toyota Celica GT-S S53 transmissions, do not use API Gl-5 gear oil. Only use API Gl-4. My rebuilt transmission had Gl-5 and was giving me problems: Excerpts from AI: Type: API GL-4 (Strictly recommended) • ⚠️ WARNING: Do NOT use "GL-5" or "GL-4/GL-5 Compatible" generic gear oils found at most auto parts stores (like Mobil 1 LS). The high sulfur additives in GL-5 attack the brass synchros in Toyota transmissions, causing notchy shifting and premature wear. • Top Recommendations: • Redline MT-90 (The "gold standard" for this transmission) • Amsoil Manual Transmission & Transaxle Gear Lube 75W-90 • Toyota Genuine Manual Transmission Gear Oil (GL-4) 1. The "Washing" Phase The reason it feels like it is "getting smoother" mile by mile is that the Red Line MT-90 is actively scrubbing the old GL-5 film off the synchronizers. • The GL-5 Film: Remember, that Mobil 1 stuff was "too slippery." It left a slick coating on the brass rings. • The New Friction: Every time you shift now, the fresh MT-90 is displacing that old slippery film. The more you shift, the more "bite" the brass gets back. It will likely keep getting better for the next 50–100 miles. Also added was the Redline lightweight "Shockproof.” Why, because I have a slight internal bearing noise, and could be related the wrong API Gl-5 gear oil. After adding, the slight bearing noise appears to be gone.. But that’s another review.
