42804 Full Synthetic Gear Oil, V-Twin Transmission Oil with Shockproof - 1 Quart

Quality stuff. Won't run anything else in my SG.

I've used this oil since my first Harley in 1996. Smooth quiet shifting. This is all I use as well as red line primary and engine oil.

Wow!!! I won't ever run anything but this from now on! Shifts like butter nice and quiet clicks into gear very smooth. Perfect for my 2011 street glide. Do it you won't regret it.

Like the Red Line products so far.

Put in my street glide. Good stuff so far. Shifts a heck of lot quieter and finding neutral isn't an issue thus far. Think I like it better than amsoil's trans fluid.

Fast delivery and worth the money.

I decided to try this on the advice from my Harley dealer. I was complaining about the loud shifts down to 1st gear, hard clunks when shifting and the noisy 5 gear whine in my 2007 Road King with the six speed transmission. It is a know problem that 5th gear on theses transmission is noisy, it is a straight cut gear which is noisy (thats why they fixed the problem later). I tend to be a bit conservative when it comes to venturing outside of genuine Harley parts and accessories. I have always used the SYN3 in all three cases on the bike and switching to something other than the Harley oil took me a while to do. The Redline oil is certainly red!! Looking like red Peto-bismal versus what I would call traditional transmission fluid or oil. It is 100% synthetic which was a must for me and changing it was as easy as could be. If you are unsure on how to do it there are lots of videos on the web outlining how to do it. I did a quick 75 miles run after the change and there is a big differance!! Shifts are smoother through all the gears, 5 gear is significantly quieter and I also believe the bike feels a bit less "buzzy" than it did before. Have just come back from a 1800 mile 4 day ride I certainly believe the changes are more than just in my head. I am a believer in this product and will use it from now on!

Excelente

Fixed hard gear shift changes, and less noise!

Have been using red line transmission oil and primary oil for years in my harley. Very happy with it. Is very high quality oil

It's the only transmission fluid I'll use in my Harley. Super slick shifts.

Works great make transmission shift alot smoother
