Valvoline Syncromesh Manual Transmission Fluid 1 QT, Case of 12

I ordered the Valvoline Synchromesh for my 2001 Jeep TJ with the five speed manual transmission. This transmission requires the gear oil for yellow metals. The transmission was grinding while going into second gear, especially when cold. The Jeep has 190K miles on it. I ordered 4 quarts and only needed two. I also ordered the AIGMISON 3L Transmission Fluid Pump to make it easier to fill the transmission. It worked like a charm. After changing the gear oil, the shifting is noticeably smoother and it doesn't grind . It was grinding almost every shift into second gear and once in a while going into other gears. I would recommend this gear oil for the Jeeps that need the GL-4 oil. It is the best priced oil I could find that meets the spec.

Everyone says to use royal purple. I have used this valvoline for years and never had any transmission problems. It meets the specs for the NSG370 and performs well in cold and hot weather. I wish it were offered in the squeezable bags like the gear oil comes in now. BTW valvoline if you read this, why can’t you add some kind of straw to the tops of these bottles to make it easier to get into the trans??

First time changing my own fluids and this made it super easy. Used on a 1995 Jeep Wrangler YJ. I would say that it massively improved my shifting performance. I used to have a grinding sound when going into reverse and now the sound is nearly non existent. Great quality for the price.

After running Pennzoil Synchromesh for 30K miles in a remanufactured transmission on my Jeep JK, I switched to Valvoline based on reviews I've seen in other forums. The Pennzoil bottle says its product meets GL4 specs, while the Valvoline website says their product meets GL5. I wouldn't have believed that a change in brand would have made a huge difference, but I'm impressed! Previously, I would have to occasionally make two attempts to shift to first gear, including having to double clutch on rare occasions. Now I can move smoothly through the shift gate with no issue and the transmission is even quieter than before. I can wholeheartedly recommend this product.

Unknowingly put GL5 oil in my manual transmission. It became difficult to shift into first and sometimes second especially when cold. Investigating the issue and found that I needed GL4 synchromesh fluid since the GL5 is harsh on the brass gears. Anyway, put this fluid in and shifting is easy once again.

Understanding my ratings: - 1 star - absolute junk, don't buy - 2 stars - it works but wasn't worth the money - 3 stars - I got what I paid for - 4 stars - It's a good value for what you pay - 5 stars - GOAT - better than expected and really good value 4 stars as this is a great value in comparison to the Mopar equivalent.

There are diff MTF for different operating conditions and transmission needs. The Valvoline MTF is perfect (just the right viscosities) for my LT95 transmission and transfercase.

Way cheaper than some elitist oil… but! In a jeep JK six speed manual transmission, rubicon 2008- it shifts smoother and better so I am happy with it. Truth is, high end oils are pointless if you change your transmission oil often enough

Perfecto para civic si 2012

A très bien fonctionné avec ma mazda 3 2015, je recommande.

As described

Buen producto. En la página ni en el producto vienen las especificaciones de viscosidad. Pero en la ficha técnica aparece la Viscosidades cinemática a 40 y 100. Lo que viene siendo dentro del rango típico de un SAE 75W-80 en GL4. Entonces si necesitas un gl4, para syncros, es un aceite bueno. Yo queria el Amsoil syncromesh pero es casi importable de conseguir en mexico. Lo uso en una transmisión manual de un honda fit.

Works well. I have 400,000 kms on my trans and no bearing noise and smooth shifting.
