I use redline in by Baker tranny and Mobile 1 in the engine and primary. I thought about switching to another brand in the tranny at one time but my mechanic told me once you use Redline, you can't switch back. Guess it's due to fact that it coats everything and would be compatable with another oil. On the bright side, it's and excellent oil.
You won't regret using the Redline products. As for their tranny fluid, Redline Shockproof is the only way to go. Only reason you can't switch back to something else is that you simply wouldn't want to after using the Shockproof.
Another RedLine user and as was mentioned, that funnel is the chitzzzzzzzzzzzz
Been buying from racerparts since they bought out My Oil Shop which I used for 10 yrs
Just changed to the Redline V-Twin package from Amsoil. So far so good. I do think the valve train noise is quieter. Cannot tell any difference in the shifting clunk. Think I will try the 20w60 at next oil change. Got mine from racerparts, free shipping.
