Shift quiet and smooth!
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.

If you have a H.D. Dyna, you NEED THIS!
HUGE difference in gear box sound and feel! Smooth and slick shifting. I am sure this solves the well known automatic tensioner problem too!!! ONE THING very interesting to know is that it is NOT compatible with engine style oils and would NOT be a good idea to add to ANY existing oil ~ YOU MUST use this at REPLACEMENT. I poured this oil into a container with the engine oil and it CLEARLY SEPARATED!!! BTW, It’s REDLINE! What’s not to like?!

Great Quality
This is my go-to V-Twin transmission gear oil in my Harley touring bikes. Great quality oil that keeps my transmissions in tip top shape over the years. Just make sure you change your fluids regularly.

Good quality.
Redline is great transmission fluid for the Harley. I won’t run anything else. Smooth shifting. Amazon got it delivered quickly. Very happy.

The only trans oil I’ll put in my five speed.
I have been using this oil in the primary of my track day Buell XP 12 since 2006. Lightyears better than the HD branded stuff. I know that it’s a full PAO base synthetic and I know it has the correct additives package for an HD primary straight cut five speed. 20 years of spirited riding and I haven’t had any issues related to the transmission. It handles southern summer race day temperatures and the occasional ham fisted shifts with out blinking. Some of my riding buddies, use it in their sportsters that they ride as regular commuters, through city traffic, year round. I like it, they like it, what else can I say?

Good gear oil
Quality synthetic gear oil. One reason I like it is the red color is east to see on dip stick.
