Product ReviewsRed Line 50204 MTL 75w80 Gl-4 Gear Oil Manual Transmission Fluid 1 Quart

Amazing product for VW manual gear box

Transmission in my 2003 vw Jetta manual was grinding at 150k miles. I replaced with OEM VE fluid and it was worse. I tried this redline MTL fluid, and shifting is smoother now at 260k miles than it was at 60k with factory fluid!Read full review...

Works like magic

This is the best sycromesh oil I have ever used. I have tried and tested Royaol Purple, Amsoil and Pennzol and they didn't work as well as this Red Line in my Jeep 5 speed transmission. I also put it in my Triumph Spitfire and worked like magic. Well worth the money.
am a 72 year old gearhead and have been around the block and tried them all.Read full review...

Good stuff, just hard to find, so buy it here.

Easy to install, not nearly as thick/viscus as others, so it goes right in. Went into a Dodge diesel, 2004, with a 6 speed manual. It likes it. Put in an extra quart through the upper PTO bolt hole, the rear bearing will thank youRead full review...

Noisey Jeep....

My Rubicon 5-speed sounded like marbles were rolling around inside. Drained and refilled with MTL. Huge difference!! Would highly recommend .

Great transmission oil

Made my transmission shift like butter. I’ve read a lot about this oil in the Honda forums and made my rsx transmission shift like butter can’t wait to take it to the track.

Red Line MTL for smooth shifting

Works excellent in Mazda Miata 5 speed manual transmission. Smoother shifting and no additives that damage nickel parts in the unit.

Easier Shifting

Great product. Made my 02 Wrangler shifting much easier and its somewhat quieter now.

Good Product

I replaced the manual transmission fluid on my e46 and it feels good. Noticeably improved the smoothness of the gears.
