Used in my 4Runner rear differential & transfer case. Jury's still out but I feel confident on the product. I replaced Amsoil Severe Gear with this one. Didn't come with the screw on nozzle like others do so I had to pump the fluid. I bought this for my transmission too. Well, after calling Redline they informed me that GL4 was correct to use. Although my owner's manual says okay to use GL4 or GL5. GL4 is the way to go. Much smoother, shifts fast. The previous oil was GL5 Amsoil. Purchase MT90 for your manual transmission, if in doubt. Call Redline customer service.

I used this product in my 2002 Subaru Impreza WRX (Sedan)(manual transmission). I actually had to return this product and get the Red Line 75W90 NS. If you are looking to put this fluid in your car, I would recommend contacting Red Line directly to make sure you are using the right product for your application...before you purchase it. Read the label on the bottle to make sure it is used in the proper manner. It is a great product!

The product does help with allowing the car to shift cleaner.

The shifting feels "lighter". Would recommend!

This is excellent for rear differentials, if you want Red Line for your transmission use Red Line 50304 Manual Transmission (MT) 90W Gear Oil 1 Quart I had GL5 in my Toyota Pickup transmission, it worked OK, but the MT 90 allows for smoother shifting.

Amazon has a better price with the free shipping than an online racing mail order place. I ordered 6 of the MT90 and 4 of this gear oil, they were individually in plastic ziplock bags and all arrived in perfect condition.

At first, I didn't really notice any difference in my shifts. However, after about 500 miles, the shifting is noticeably easier and smoother than it was prior to the change. I'm glad I waited to post the review, because it took a few miles to really shine in my old 4x4. I would definitely recommend this stuff if you're looking for smoother shifting in your manual tranny.
