It works well for my friend’s manual Jeep. It makes it shift a lot better and it is pretty good quality. It is say to put in if you have a pump to pump it in from the bottle to the transmission. It helps to stop leaks and is quick to dip it in. The only issue is that it is expensive.

No he notado ninguna diferencia ni mejoría respecto al aceite de transmisión de la marca Honda. Esto quiere decir que es un producto caro para lo que ofrece. Probé un producto de una reconocida marca alemana y he notado una diferencia importante, las marchas entran mas suaves y no me cuesta meter la marcha atrás. Mi conclusión es que es un producto caro para lo que ofrece. El aceite de transmisión de la marca alemana es a mitad de precio y me va mucho mejor.

I have been running it in my transmission for a bit over a week now, it has not caused any issues with shifting and I think the transmission is actually quieter. I used it in my NV3500 1994 Dodge Dakota 4x4 application. It was half the cost of the factory oil, and the factory oil is getting very hard to find.
