50204 SAE 75W80 API GL-4 Manual Transmission and Transaxle Lubricant (MTL) Car Gear Oil - 1 Quart (2 Pack)

I have an '07 BMW 550i with a stick shift that I picked up this past summer. No idea when or if the transmission oil was last changed. The gearbox mostly shifted fine, but there were times it was reluctant to go into gear, and crunched a weee bit on occasion, so I figured a transmission oil change was a good first step. BMW, of course, only recommends their own $50+ per liter solution, but this redline MTL was recommended on a couple of sites / forums @ half the price. Oil change was stupidly easy, with the worse part being the removal and reinstall of the underbody tray. Note that the car does need to be level in order to refill the gearbox properly, so that may be easier for some than others. I am fortunate enough to have a lift, so it was <30min job. It took a full 2qts, so if you have an e60 V8 BMW manual, you may want to grab a 3rd qt just in case you have some spillage. There are plenty of online videos with instructions you can search for help. The old oil in the gearbox was definitely well used, but not so terrible that I would believe it to have been the original oil. BMW has this stupid concept of "lifetime fill" with transmission fluid for the past ~20 years. This obviously discourages proper maintenance, so it really wouldn't have been surprising to find original fluid in a 16 year old car with 110k miles. I did the differential fluid as well with the redline oil recommended for that application. I did not notice much of a change the first couple trips after the oil change, but after 50-100 miles, I could definitely tell the difference. Every shift has a more "syrupy" feel to it, and the shifts slot into place with a more positive action overall. This gearbox still doesn't like to be rushed. This MTL fluid won't turn your BMW into a Honda, but it definitely works well and costs a lot less than the "genuine" oil. Definitely a worthwhile job to perform yourself, if you are able, and a great product to improve the driving experience.

Noticeably smoother after replacing fluid.

This came highly recommended as a replacement for the OE MTF in my FL5 Civic Type R. After driving around for a few weeks I can say the shift quality improved - especially shifting to/from 2nd. Cold-start shifting is also improved somewhat. Overall I am satisfied. The FL5 CTR takes a little over 2.3 qts.

This stuff is fantastic! Used this for a manual 2013 Jeep Wrangler at 100k miles. Transmission is smooth and no issues at all. It's challenging to provide an honest review of transmission fluid, as it's subjective to the vehicle itself.

Absolutely the best! Shift quality is even better than the O.E. lube. Especially below 40F degrees. O.E. fluid was slightly notchy below 40.

A good quality fluid. I used this in my 2004 Cooper S. The 2 pack is the perfect quantity.

Pros: - Price per quart is significantly cheaper than Motorcraft XT-M5-QS - Good quality fluid that shifts smoothly once up to operating temperature Cons: - Cold lubrication is not all that good. Gears feel “crunchy” and hard to shift when fluid is still cold, not at all comparable to the performance of the Motorcraft equivalent in cold conditions Overall, good value for the few times you need to change your transmission fluid. Shifts well and keeps the transmission nice and quiet. Cold lubrication still leaves a lot on the table but is still much better than other cheap brands of gear oil that often do not shift well even at operating temperature. This particular fluid helped with my “crunchy” 6th gear shift in my NC Miata even though it can be hard to shift when still cold. Worth the price, though I will probably give the Motorcraft fluid a try next time to see if it’s worth the extravagant price.

I recently had issues with my NV3550 making noise and shifting rather difficult at times. Flushed my transmission and installed this fluid and wow what a difference. Shifts like it's new and no more grinding when shifting. Highly recommend for Jeep TJs with manual transmissions.

Excelente y sintético en esa especificación, excelente para mi Swift Sport estándar obviamente, máxime en 75w80.

Excellent service and product. Haribo sweets is a nice touch with delivery but could do with a bigger bag 🤣

並行輸入品とのことですが、容器も全く傷などなくきれいなものでした。 梱包も問題なく、配送トラブルなく迅速な対応でした。オイルそのものは 評価の基準がなく、変速時のスムーズさは交換前より心なしかちょっと良く なった感じがします。

Amazing product

The Best Ever!
