Questions & Answers

What do you think of mixing GL- A gear oil that contains GL-4 How much gear oil do you use? Do you know what difference is? Do 50/50 if possible. Would it be good to work Does it matter whether it matters or ?

This is not OK at all. Good luck. A transmission with bronze or brass parts should use 4 instead of 3. Good luck. There is a chance that part 5 destroys Having experienced it myself, I can vouch for it. It was a mistake by the speed shop to give me a With the X-body, I have the 5 for my 91 YJ This is the fifth translation. It wasn't more than ten miles away before I smelled the odor. The company made good on the mistake and gave me a gallon of the The shift in my X5 was much better at 150K than it was at 100K. Now that it has 185K, Troy Transmissions is happy that I want Redline. He insists that my car be in synthetics because of Arizona heat and drivers who get in extreme conditions, such as the "back way to Crown King." The owners of the Y should be aware of this. Take care when you go to a fast lube shop. visited two different shops and BOTH told me to It was lube 5 that was the correct choice! NOT AT ALL! Fortunately, I declined the $450 they offered me solely to change fluids, and I did the right thing as any Jeeper would. Your own rig must be built by you.

A 1995 Jeep YJ manual transmission uses MT 90, is that a good ?

I am happy with the product I bought the car used and I had no idea what kind of transmission fluid it used. My jeep sounded like a bus and when I added the MT-500 it sounded even worse The biggest difference lies in how quietly the change is made.

What is the reasoning behind many saying that we shouldn't change the old gear oil & that it may cause problems with new gear oil due to the "gunk" in the old gear ?

Automatic transmission fluid is the term they are referring to. A worn out automatic transmission has friction materials which are smoothed out on the friction side so they slip. This happens because the friction materials in the bands are bonded to the friction side of the transmission. This redline gear oil is a transmission fluid used in manual transmissions since automatic transmissions are driven by hydraulic pressure. The "gunk" in the old fluid will aid with "gripping" action with any band. There is no reason to apply the old saying

Could this product be fitted to my 1975 VW Type 1 Beetle, which has a engine size of 85 w/90 gl - How much gear oil do you need? Are you able to produce a synthetic product like that?

For engine oil, it's okay to fool around with weights, but I wouldn't put the wrong weight in a transmission. I suggest looking on the Volkswagen site or calling the Volkswagen service department.

Selected User Reviews For Red Line (50305) Manual Transmission (MT) 90W Gear Oil - Synthetic Gear Lube - 1 Gallon

For my Toyota Pickup from 1990, I need gear fluid

5/5

Toyota forms say this is the best - I can verify that they aren't lying. Also, it is a good deal. It almost completely brought my old (245k miles) trans back to life, but you have to remember, it had been neglected by the previous owner. If it wasn't shifted just right, it would pop out of first, grind into second, and finally grind into fourth. Now that the transmission fluid has been replaced and the bushings on the shifter have been replaced, the transmission runs much better than it did before,.

Gear oil of the highest quality! When I rebuilt the manual transmission in my '99 Jaguar XJ (Aisin AX15), it was quite loud

5/5

For the most part, I got used to It seemed like magic, so I decided to buy it, but I had heard that it was worth the extra money. Without hard proof, there was no way I was going to believe that kind of hype. It wasn't worth it, but I had a credit on Amazon, and I needed a fluid change anyhow. This is amazing. After seeing the hype, I believe it now. As soon as I rebuilt my system, I should have followed up on this. Getting the shift to quiet down resulted in a smooth shift rather than a choppy one. It still doesn't make sense to me. The idea of using it for something else is now appealing to me. My favorite way to lubricate everything has always been to use a vintage squeeze pump oiler I have. I put what was left in the bottle in It is a bold claim to make that this will resolve your entire world issues, and I've heard that people are less than impressed, especially given the However, this is a very interesting piece of work for me. No idea what kind of magical pixie dust they put in there, but even at a cost more than twice the price of competing gear oils, it still does the trick. It's the only product I'll use from now on.

This model is the Mazda 3 The GL- function should be used Not an answer to the In my 2010 Mazda 3 6-door, I had just had my manual transmission fluid changed As I looked at the transmission, I noticed it was very stiff and that the My experience was the same after I had purchased the product

5/5

I like to shift after the service. Later I realized that GL- may have been written on the container Instead of GL-, please use 5 in Despite several times verifying the number at my local shop, I was unable to get ahold of the number. It turned out my suspicion was correct. After I purchased the Redline, I took it back to the shop and told them to dump the Mobile 1 transmission fluid they had used. Day and night are two very different things. As I use Mobile 1 for engine oil, I had the opportunity to talk with a different technician who admitted that Mobile 1 in their shop was GL-rated I have 5 oils - The GL- will not be modified It had been requested and confirmed many times already.

Now shifting is as easy as butter. The surface is smooth and there are There's no way to describe it. It's Here's some advice The shop can tell you it's GL- even if it says otherwise To avoid the problem, I suggest taking the bottle of the right formulation to whichever store you use - When I give it to them and have them put it in - The supervision of It's better to do it yourself than hire someone.

Don't wait

5/5

Do it right now. There is just no way to describe how amazing this stuff is. In fact, I would go so far as to say it is mandatory in manual transmissions. It makes the thing shift like new after three years in a Nissan transmission with a few hundred thousand miles on it. I like it so much. It also worked in a Toyota I was very worried had a bad transmission with faulty 1st and 2nd synchronizers and a noisy 5th gear and it made shifting much easier. There was a drastic improvement in the noise level in fifth gear. Thank you, G- The brass syncronizers are the only ones with low sulfur levels. There are no snakeskin oils in Redline. You will be amazed by the results when you buy new fluid and swap it out. There aren't enough excellent things to say about me.

I cannot think of a reason why Redline products wouldn't be good

5/5

A manual transmission oil such as this is without a doubt the best out there. The price is high, but Amazon appears to be the best place to buy it. Most people will find it more economical to purchase a gallon of fuel. Having said that, the shifting system itself is much smoother and easier as a result of the improvements to performance. As far as I am concerned, it works great in my rock crawler. You put a lot of effort into the oil! Even though I have never done a proper lab test to determine what impurities are in the oil after use (which is the only way to know exactly what's happening inside the transmission), each time I replace it, the oil comes out just as clean and clear as if it were While I used other, lower quality oils before, the oil came out very dirty during oil changes with those oils.

During the winter, you can dispose of your garbage outside

3/5

My manual 2009 Jetta has only had one drain and fill (I only drained and filled one). As temps dropped from 60 at the time to 24 now, the oil is absolutely useless in cold weather, and I had trouble shifting this morning. This gear oil may be OK in warmer climates, but forget it in cold climates, I'm back My car began shifting fine immediately after my clutch was changed, so I decided to change the oil at 60k since the clutch change. I used 5 quarts of this oil and would not recommend it to anyone. The error.
