I put 30,000 miles on my TKO600 on the street. It has always been hard to shift. When I was doing burn outs at the 2013 London Cobra Show I missed 3th gear 9 out of 12 times.
I told my buddies I was going to do something to fix my trannie.
Someone told me about Liberty Gears. I emailed them and bought their street up grade for my trannie. $331
I pulled my trannie and a friend help me swap out the parts.
Best money I've spend in a long time.
Not what I would call smooth, but I can not miss a gear. Even 5th is very easy to fine.
Maybe it will get better with a few miles on it.
Yes I would recommend Liberty Gears!!!!!!
