Smooth less noise ๐
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.

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.

Best oil for Harley period
Oh yah i sware by this stuff i own a harley with a 103 motor i run redline in trans engine amd primary. I know this stuff works because i have a digital heat gauge on my harley and it runs significantly cooler then any other oil ive ever tried.. and comes out cleaner..

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, Itโs REDLINE! Whatโs not to like?!
