i here just wondering how dennyo got an avatar of my X.

 

Yep. I had regular dino 75-90 in my tranny, and changed it to Mobil 1 75-90, and it has not leaked yet, but it does not shift as nice as it did with dino. I changed out my motor oil back to dino, guess I will change the tranny too. Maybe mine just likes dino better.

 

 

all the dealers but 1 around here quit putting sny3 in trannys two ago, unless requested.
two of them said HD no longer recommended it in the tranny..

I has ok with formula+ but last yr went with belray Hypoid 80-145, feels a little stiff on first 5or6 shifts when cold,, and its below 65... so this time I am going Mobil1 75-90

 

I just put in the recommended HD tranny oil... same price as the Syn3 anyway and I figure I might as well play it safe.
