This Red Line manual transmission fluid makes your transmission shift smooth as butter.

Really like this 75w80 GL-4 MTF from Redline. Works better in my Honda/Acura than Torco MTF. The Torco fluid is really good stuff (I think better) but I picked up a vibration out of 2nd gear, perhaps it was just too slick for the differential or other MT components. This Redline 75w80 GL-4 MTF is of a lower viscosity than the Torco and seems pretty comparable (only in viscosity) to the Honda HG MTF which sounded horrible in my car and wasn't very smooth. My service manual originally recommended 10w-30 motor oil for the MT but then Honda came out with the MTF HG stuff which I tried and immediately switched it out. This Redline is really good stuff and is in the high quality category of Torco, Motul, Mobile One, Amsoil. It's really good, but generally there are certain lubricants that will work better in your car or motorcycle than others. You just have to try them out and unfortunately that can get pretty expensive, since this gallon option was basically $15.60 a quart. Do the research and limit your selections. Since the manual recommends 30k transmission oil changes, this long interval would justify the higher price per quart.

Replaced my 2000 Jeep TJ transmission oil with redline, noticeable improvement as it seems to shift smoother. Glad I purchased this oil based on others recommendations.
