Transmission Oil Change Interval

[Trikeconvert]

Redline, in all three

I know it's probably excessive, but I change mine every 5k with the oil change, I use the Redline with shockproof.

I've been using Redline for years.

All three every other oc. Just easier to remember

I personally don't know anyone using the new HD tranny/primary lube. I currently have Redline Shockproof in the tranny & it's the best I have tried, so far, after 5,000 miles of use, it looks perfect & the tranny just loves it. I have HD Formula + in the primary & have 1 more quart to use, then it gets Redline primary lube.

If I was concerned about thr tranny to primary migration issue, I would run the same in both holes. I had Lucas full synthetic 20w50 motorcycle oil in all 3 for a while and my FW performed well & better than the HD Syn 3 they used at the 1,000 mile service. The Redline is just better for the tranny.

I run Redline 20-60 in the motor , Shockproof heavy in the trans and Formula +in the primary, I have been wanting to try HD Gear Oil 80-140 in the primary, Local dealer still does not carry it. But I would like to hear from anyone that is using it in there primary and what they have to say about it. Thanks Doc

I easily have enough fluids for the next 2-3 years & need to stop finding good deals.

In honor of Jack's love for oil threads, I will be starting a 2020 holiday oil thread around Xmas, so stay tuned. I would like for everyone to chime in with their favorites.

The only reviews I've read so far, on Harley's Heavy Sync Gear Oil, are the ones posted on the HD Online Stores Review Page.

I have not found it yet to try it. Thanks

With my prepaid maintenance plan at Space Coast HD, they change all 3 holes with Syn 3 (or your preferred) every 5K. Now that SCHD has opened Miracle City HD , right down the road from me, I renewed for another 20K plan.
