This is GL-4 and they quit making this. Making it more expensive. The dealership replace transmissions now with GL-5 which is not good for yellow metals and causes corrosion. Since it’s cheaper for all to use GL-5 that’s what dealers/mechanics are putting in for transmission flushes. I bought this 75w-90 GL-4 at a good price and it’s definitely worth putting the correct fluid in a high heat tranny. Especially when your manual states to use GL-4 “only” so yes I highly recommend using GL-4 75w-90. In high rev high heat trannys.

I’m running a trick out 2013 v6 4.0 liter Daily Driver/ Rockcrawler with the original trans. Since I beat the crap out of my truck I change all fluid in the drive train and axles ever year. I used all sorts of manual Gl-4 & GL-5 fluids but this one takes he cake....

This stuff is amazing! I just bought a small used car with a manual transmission. When cold, shifting into third gear resulted in a slight grind, upshifting or downshifting. When warmed up, no problem. Internet search found people recommending Redline MTL. I put it in several days ago. First drive, the problem wasn't gone but improved. After several days, problem appears to be nearly completely gone. Buttery smooth shifts. Wish I'd known about this product years ago.
