Harley Trans. Lub.
"I had always used HD Formula+ in my Heritage Softail FLSTC transmission. I had heard that HD might stop producing Formula+ so I researched what others were using in their HD transmissions. The search brought up a lot of alternatives, of which one seemed to have specs and comments from a small group of riders that stood out to me. That product was Golden Spectro's lubricants. I decided to order and try it. I changed the fluids in my bike this season and the Golden Spectro gear lub went into my transmission and wow what a difference it has made, The shifting is smoother, the klunk that was normal for my shifts changed to more of a click for both up shifting and down shifting. Finding neutral is also much easier. The improvement didn't take long, it occurred in just a few miles over about a half hour. I would not have believed it if I had not experienced the improvement myself. I wish I had found this a long time ago. I'm ordering more to have available. I hope your results can be as good as mine if you decide to use this lube, I'm just glad I found it."
