Took your advice and swapped for the H-D 80w-140 gear oil in both primary and trans. The primary was immediately quieter after idling for just a few minutes. I haven’t had time to ride it but it seemed to drop into first much softer.
Not the cheapest stuff at $20 per qt but about the same as...
You are correct. The 171 fits my H-D. 138 is for my son’s Suzuki C50.
Also, I’ve decided I don’t like the Redline primary fluid. Lots of noise that wasn’t there with the Formula+. I’m going to switch back asap.

Replaced with the same stuff. Also changed the primary oil and trans to Redline.
Filter is a Hiflo HF138.
I’ve had a mix of foreign and domestic.
My 2003 GMC Yukon was one of the best. I also had a 1997 Ford Explorer V8 that was super reliable. My current 2014 Tundra has been great. We’ve had 5 Honda’s that have been a mixed bag. Our first Odyssey has trans issues but our 13 Honda Pilot was a rock...

Best truck I’ve ever owned. Absolutely dead reliable and pulls like freight train.
We have two Theta II engines in the family - daughter's '18 Sonata 2.4 and son's '11 Optima 2.4. So, yeh, I'm quite certain we will have an engine replacement story someday very soon.
Yes it had the KSDS recall done. The engine doesn’t sound all that healthy and It burns about 1 quart of oil every 3k miles. I’m sure it’s on the road to replacement very soon.
After a morning ride on the H-D around Lake Mead (or what’s left of it) I did some work on my son’s 2011 Optima:
- New front sway bar links that fixed the front end rattle.
- New airbag clock spring that fixed some inop steering wheel buttons and the heated steering wheel.
