### ⭐⭐⭐⭐⭐ 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!
*by B***H on May 7, 2025*

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?!
