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

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!

This is an excellent product for cars with manual transmissions requiring GL-4 rated gear oil, specifically for 75W-90 weight. Putting gear oil that is GL-5 or dual rated GL-4 / GL-5 can potentially cause damage to the soft metal components inside your transmission. The high sulfer content in those gear oils can eat away the synchros inside your transmission, making shifting more difficult. This gear oil is safe, and specifically designed for use in manual transmissions. It won't eat away any of the components, and it leaves your car shifting smooth. I mistakenly put a dual rated gear oil in my wife's manual transmission. I thougt I would be safe using a GL-4 / GL-5 rated oil. I left it in there for about a year before discovering my mistake. The transmission didn't shift very well, and it was making grinding noises while driving. I eventually drained the fluid and replaced with this. Upon draining the oil, there was a lot of gold colored flecks that came out with the oil. That was material from the transmission synchros. I replaced with MT-90. The shifting improved greatly, but the transmission had already been damaged too severly. I ended up having to replace the transmission. I drained the gear oil at the time of the transmission swap. There were no gold flecks with the MT-90. The damage had all taken place prior to using the redline MT-90 gear oil. The new transmission was filled with MT-90 as well, and it has not had any issues. Pros: -one of the few available GL-4 gear oils on the market -Designed specifically for manual transmissions -reasonably priced Cons: -None (for the oil itself) -not avaialbe for sale off the shelf at most retailers (not a con of the product itself at all, especially if you are looking to buy through amazon) Like I said above, if your car's manual transmission requires GL-4 rated 75W-90 gear oil, then this oil will meet your needs and be safe for your transmission.

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

Great product. I've been using it for 217K miles. My transmission still works like new.

Exactly as described. I needed the GL-4 for my 2015 Toyota Tacoma. The gallon size was more convenient for my needs.

Makes my old AX-15 shift better than a new one. The synchronizers in that old transmission didn't like the standard gear oil much, but this stuff has something in it that makes them work so much better. I've never had such ease of shifting than I've had with this.

Works great in my 2nd gen NV4500

Used it on my 2005 Tacoma manual transmission and shifting went from clunky to smooth.

Well not really, but it brought my transmission back to life on the very first drive after putting it in. I can now get back into first and have almost completely cured my crunch getting into second. All other gears are just fantastic. Is it because my transmissions gear oil just hasn't been changed in too long, or is it because this product actually is magic? I'm not sure to be honest, but I will for sure be buying the same thing again next time. Bought for 1998 Jeep TJ and have a small amount left over which is also excellent.

Good oil and GL 4 rated for older cars

私の車は2.6L入るので３本で使い切りれました。
