Red Line 50205 SAE 75W80 API GL-4 Manual Transmission and Transaxle Lubricant (MTL) Car Gear Oil - 1 Gallon

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.

Great stuff, we use in LADN ROVER Transfers for 1987-on wards in Defernder/Dicso/RR; just over fill buy a PINT to get mainshaft lubed correctly

I have used this in both of my late model Mini Coopers. Shifts smoother than standard fluid and my transmissions seem happy running it!

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

Nice product, good value

Excellent manual trans oil which solved my problems in my 2000 f250 zf5. I had synchro issues/grinding into 2nd and 3rd gear. After filling with this oil, I have zero grinding. Hopefully its still flowing well enough into the bearings, but for now, I'll take it as a win.

On some Geo Tracker forums it was recomended that a GL4 gear oil be used in the transmission because of yellow metal parts. Before the change it was difficult to go from first to second gear when cold. I drained the old fluid out and replaced with Ford F type transmisson fluid and Marvel Mystery oil. I ran that combination for 1000 miles to clean out the transmission and transfer case. I drained that out and replaced with the Red Line oil. After doing this my transmission shifts more smoothly. I noticed a 2 MPG increase in fuel milage. The transmission is still noisy but that's probably due to the fluid level being low from the previous owner and the 138,000 miles on the vehicle.

I traipsed around the Internet for a bit looking for a solid transmission fluid. I had used Redline in the past but it had been a couple of decades. At 50k miles I decided a change was in order and this MTL fluid shifts quick and quietly. I have no noises from the gearbox that I had before.

Used in my Jeep Wrangler 1998 Renegade. Transmission is like new no more grinding!

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.

Made shifting easier. Original fluid in mini’s ARE NOT LIFETIME!!!! Change it and use this stuff.

Just what I wanted and needed . Thank you

Easily the best transmission oil out there! I run this in our Jeeps and they shift much smoother. Highly recommend!
