Improved gearchange smoothness
This is good stuff. It made my gearbox far less 'notchy' and just generally slicker to use than the manufacturer's official fluid.

Normal, nada especial.
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 should have done this sooner..
I just bought a Chevy Silverado...the one I always wanted...regular cab..short bed..4.8L V-8 and manual 5 speed...the guy I bought it from was meticulous in his servicing of it. It's a 2004 with 125,000 miles..not a squeak on it..really tight....engine sounds good..runs great...transmission the same way...I decided I was going to go with Royal Purple from one end of the drive train to the other...the engine, the transmission, and the rear end...drained the engine oil and removed filter...put on a new Royal Purple filter and 6 quarts of Royal Purple 5W-30 oil..what the factory recommends..the I drained the manual transmission oil...pit in Royal Purple Synchromax....I ran out of time to do the rear end but I will do that in the morning...took her for a spin...I thought to myself..I want to see some astonishing results like everyone else....Strike me dead with Lightning...I thought this truck was quiet and tight...I didn't realize the noises this taken away....All I can say is that I feel like I'm driving around a piece of velvet....I am so glad!!!! I decided to go with Royal Purple...I'm sold....Now for the rear end tomorrow...I'm thrilled....
