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?!

Good stuff!

Amazon was a day late delivering, always when i absolutely need something....anyway, Been running this about 10,000 miles now and definitely feel a difference from the standard 20/50. Smooth shifting and zero fuzzy's on the drain plug last change so cant ask for much more.
