Ditto to that! When I bought my 09 egc the dealer had 75/140 Belray in the tranny. When I did the first service I switched to Amsoil 75/110. I like it much better. smooth and quiet! Amsoil 20w50 in the motor and primary.
I had never used Amsoil before. Didn't like the way it was sold. The Dealer where I have it serviced sells Amsoil. Since then I've noticed alot of Dealers selling it.

 

I've been following this thread and was wondering those using B&M Trick Shift which one you using, original or the Syn. Thanks for any feedback.

 

ATF is 10 wt. works fine in a syncromesh transmission like a Ford or Gm. i wouldn't put it in the H-D. Best i have found in H-D tranny is Redline V-Twin HD fluid. 75-250 wt.

 

B&M Trickshift is essentially Type F fluid. It has modifiers that help clutch lock up. GM drag racers use it in the automatics and I have used it to clear up a slipping GM transmission. I see no ill effects in an H-D primary.
