Well it is raining all day, so I decided to get the Syn3 out of my trans and fill her back up with Mobil 1 75/90.

Just had it serviced at 1100 miles went back with Syn3 in all 3 holes. Bikes got 1470 miles on her now, and the more I read about Syn3 in the trans, the more I wanted it out of there. I kept Syn3 in the crank and primary, I think it's decent oil for them. I've got 5 quarts that came with the bike so I'll use it till I use it up then got to Mobil 1 in all 3 holes.

What did read about using Syn3 in the tranny? I used it in my Ultra for a few years and never had any problems. Sold the Ultra last year and now have a Dyna and planned on using Syn3 for all 3 holes also. Let us know where and what you read about using Syn3 in the tranny, might make the change also.

Here's good one to start with...http://www.hdforums.com/m_154846/tm.htm

Mainly I just read alot of the threads in this forum. The more you read, the more I felt like Syn3 didn't need to be in my trans.

Just my opinion though.....but read a few posts and see what you think

Plus the fact that HD does not suggest using it in the trans any longer. Your choice here.

Thanks TC.....That thread is the main one that made me want to change.

I don't think Syn3 is gonna turn your trans to bubblegum, but longterm I agree with TC

Guys....this is TC explaining to me why you shoudn't use motor oil in your trans. Note: I went and bought a gallon of Redline Shockproof Heavy the next day. j/k

I have to admit I changed mine out too. It just makes sense to run gear oil in a gearbox.
