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

This is supposed to be the best recommend GL-4 trans fluid for jeeps with the 2.5L and 5 speed trans. I changed my factory fluid out just because of age and moisture build up. The old fluid seemed fine still but this oil did infact make it shift a little easier. Mine never had a real problem shifting but it still made it very smooth. And this will not deteriorate the synchronizers like the new fluid will. Don't use GL-5. Use this stuff.

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.

It arrived on time at a fair price and the product totally changed how my 2002 Miata shifts I am extremely happy with it

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.

The 2006-2008 Civic Si's have a 2nd or 3rd gear grind, for me it was happening everytime at high RPM's. So I got a Hybrid Racing CMC and Slave Cylinder kit, Acuity Shifter Bushings, and new transmission fluid. I have already used Honda OEM transmission fluid before and it would still grind. So I got this fluid instead just to try out and it actually does help a little bit. If I recall correctly this has different operating temperatures than the Honda OEM fluid and reacts differently to different synchros at high RPM's. For me, it just improved the overall shifting feel, everything feels a lot more crisp and tactile when going into gear which is very nice. This isn't a definite fix to gear grinds, I highly recommend getting the Hybrid Racing CMC and Slave Cylinder kit since with the new slave and clutch line, it makes installing a lot easier and it aids in the transmission responsiveness as well. Hondata will help with rev hang so you can really bang gears, Acuity and Hybrid Racing shifter cables/bushings help a lot with shifting feel. All of this and a possible transmission rebuild/repair will definitely fix the transmission problems and you'll be banging gears all day. I've only been running this fluid and the hybrid racing kit and the grinding has basically fixed itself. I grinded 2nd like once trying to powershift but it still went into gear and I chirped 2nd, but that's due to my 2nd synchro being damaged, I've literally grinded that thing over a hundred times. Motor mounts will also help a lot with reducing drivetrain shock (aka how your gears grind half the time) as well. But this fluid is a minor band-aid solution and I'm not totally sure on the reliability aspects in certain ambient/operating temperatures and how they would react but it should be all fine and safe to use. Overall, it improves shifting feel and can be a band-aid solution for gear grinds.

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.

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.

So here's the story. I have a 2007 Honda Civic with the 5 speed manual trans. It's a good daily driver all told. At about 90k miles it started getting tough to get into second gear. Sometimes the synchro refused to spin up the gear before engaging leading to destructive "gear" grinding, other times the blocking ring would not get out of the way of the dog clutch teeth. It quickly got worse to where 2nd was practically unusable at 95k. Damn!! A Google search showed that I was not alone; in fact I was part of a huge mob of unhappy Civic owners. A reman trans with installation will ding you roughly $3000 USD plus or minus (and that's without a new clutch and throwout bearing which you'll want to do if you're in there). For a 10-ish y.o. car that made me gag, and quite unhappy too. The specified oil change interval is 120k miles so I wasn't there yet. The Honda fan boys who had the same problem said that draining the trans oil and refilling with the specified Honda lube did nothing beneficial (except putting a few bucks into the mechanic's wallet). But they also said that draining and refilling with Red Line MTL *did*. So I popped for 4 quarts (the Civic manual says it takes 1.8 quarts but it is really about 2 quarts)....2 quarts to try it out and 2 more in case I wanted to change it again "down the road", so to speak. And it worked! It's not perfect; about once a month I can feel it balk going into gear so I move the lever back to neutral and try again, and then it goes in. It's a whole lot better than a spendy transmission replacement. The car has about 107k miles on the clock as of this writing. If you're one of that unhappy mob as I was it's worth a try. A quick note: Whatever lube you feed the trans, make sure it's rated GL4 and not GL5. GL5 contains a sulfur additive and will slowly consume "yellow metal" alloys which the synchro cone clutches are faced with. If it says GL5 and also meets GL4.....NO GOOD. It has to be only GL4-rated. The Red Line is the proper GL4 formulation.

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。

Red Line MTL is an excellent gear oil. This bottle was used to replace the old gear oil in my differential. I don't have a lift and was hoping I could find a product that squirted it in uphill from the add hole. Lots of product are available to do this on Amazon but these solutions assume a normal size 1 quart or liter jug top opening. These are a non-standard size. My neighbour has a complex solution that he bought but it did the trick. Maybe I'm just not thinking creatively enough but I didn't find anything else in my garage or house that would do the trick without spilling a ton of it on the garage floor., But worth the hassle for the good quality

El producto es 100% original de excelente calidad, la funcionabilidad en la transmisión es fabulosa producto 100% recomendable

Amazing product
