SAE 75W-90 Synthetic Gear Oil GL-4 | Manual Transmission, Transaxle & Limited Slip | 1 Quart

Quality product at a fair price.

20K mile and over a year later Update below after original review: I'm using this in a 2007 Mazdaspeed 6 transmission (manual AWD 2.3L turbo). It seems GL4 is getting harder to come by, my local auto parts store didn't have any in stock, only GL5. I ordered this to try it out. My transmission has brass synchros, and I've heard not to use GL5 in it since most cause accelerated wear to soft metals. Shifts are smooth even before the transmission is up to operating temp, But a little more notchy than before, but no grinding experienced yet and notchiness may just be because it's a High milage transmission @155K miles. The mazdaspeed 3&6 transmissions are a little picky with oils as far as feel goes, I don't know what fluid was in it before as I bought it with 150K miles on the odometer and wanted to make sure the fluids were changed out since unknown service history. But when I swapped the transmission fluid it looked pretty clean and new. But at least this way I know it's got the proper fluid in it. I'm happy with it, and will try their GL5 synthetic for my transfer case and rear differential next, as I just bought conventional Lucas to swap for now from the auto parts store. Will update review if the fluid starts to break down quickly or causes issues. 20K mile update as of 8-23-23: transmission still feels just as good as when I changed to this fluid, no breakdown of the GL4 has occured that I can fell. I will be changing it out again at 30K miles, or when I swap in my built motor, whichever is first. Will definitely purchase this again. The notchiness I spoke about seemes to have lessened some as well, or I don't notice it anymore. Transmission still shifts well and goes into gears with no hassle. It's a safe buy for mazdaspeed 3's and 6's for sure. And I'm sure it will work great in any other transmissions that require GL4 of this weight.

good stuff

Right oil, good price

Could be better pricing

I bought my 09' Scion tC 5 speed brand new. She's at a just 120k miles and now my daily driver. I replaced the transmission fluid with this product, and the shifts are now like butter. Car has a short throw shifter that felt a bit notchy and getting more over time. Now even on cold starts, like mentioned, its like butter. Would recommend.

Great product and great price.

Great product

This is the best option I’ve found for the specific type of gear oil/transmission fluid for a 2008 Toyota Corolla CE manual! You get 3 litters for the price of two of the other brands like red line and other brands! I put some in my car recently and is doing the job! An 08 Toyota Corolla CE manual take APL 75W-90 GL-4 gear oil so it does effect long term brass synchronizers in the transmission! Thank you Amazon for supplying this product!

Bueno

no se que tan bueno sea este producto, ya que las autoridades de laredo texas dicen que es un articulo prohibido. me gustaria me dijeran por que es prohibido el aceite de transmision, ES LA SEGUNDA OCACION QUE LO PIDO Y LO CANCELAS POR ESE MOTIVO

Need some gear oil for my jeep jk and this fit the bill for a lot less than what other brands go for with the same quality. It has a large mouth that fits my pump which was perfect.

El aceite aparenta ser de muy buena calidad y a muy buen precio. Lamentablemente no pudo pasar la aduana, ya que para TXS es un producto dañino. Sugiero opten por alguna mercancía que no amerite importación.
