I read lots of posts from touring to sportsters on the kind of transmission oil used. I have been running Red Line in my 2010 FXDC and it's ok. Shifts smooth but clunks like most. I'm looking at Ansoil 75w90 severe duty. Wondering what you are using and why. Thanks.

 

Amsoil 75w110 Summer
75w90 Winter

 

I use Mobil 1 75w-90, no issues here

 

I've been using Spectro for a couple years,the tranny shifts good with this oil.http://www.spectro-oils.com/heavy-du...nsmission-oil/

 

I use red line shock proof,,,works great for me, and I won't change,,,

Redline shockproof for my bike. Belray gear oil is also good stuff. I gave a buddy an extra bottle of shockproof I had. He said he was having trouble finding neutral but not anymore.

You can get that oil almost anywhere and it shifts nice and smooth.

 

Advice I got was Spectro 75w-140 in my '03 LR.

 

I use this stuff too. I have also used the Bel-Ray oil and it is good but not near as good as the Spectro.
