Thanks Richard!
Jack,
In my 2012 Harley transmission I changed the fluid to Red Line synthetic transmission fluid. It removed the 'clunk' when shifting. When I first poured the fluid into a measuring cup it came out clear red as usual until midway through the quart. Then it came out pink and thicker. I likened this stuff to miniature tapioca pearls (pillows). I poured the fluid back into the bottle and shook it up before measuring it out to put into the transmission. This fluid sticks to the sides of the cup 'forever' so I imagine it coats the gears in the same way.
Since then I use Red Line primary fluid and their transmission fluid exclusively. I'm not as strict at engine oil as long as it's synthetic - mostly Mobile 1 or Castrol. I don't recall using Super Tech in the engine although I favor that in my cars.
Hank like you I'm sold on red-line from my experience with it but still need to replace that synchro all my cars have taken back seat to the Newell. I need to sell a few of them.
Finished the differential oil change. Sealed two pinion bearing cover bolts since there was a "slight" film of oil. I do not like anything showing film or stains...
Bought a McNaught oil pump to suck the gear oil from the bucket and into the diff. It was also easy to drain and magnetic plug had no tell tale signs of anything concerning. Felt good to get this out of the way. Took the old oil to the auto parts store recycling tank. Job done. Next up is coolant replacement as well as lower radiator hoses since they seem swelled up from age.
Well you smoked that one job, I haven't even gotten the oil yet.
