Harley Heavy Transmission Fluid

[Jack Klarich]

I got tired of the clunking, I have tried many transmission lubes over the years, I have had good luck with Spectro 6 speed fluid , Bel Ray, and Redline
I tried Formula + once again but the clunk and fuzz on the magnet was still there
Enter the HD Heavy 80/140, nice smooth shifts again, it clicks into gear similar to Metric transmissions, Stella is happy again( side note, I had already tested the Heavy earlier, but to be fair I also tried the above mentioned fluids also

Hey Jack,

I too have tried the new HD Heavy 80/140 in the transmission and have been very happy with it.

Did you find it better than the Redline? I am not sure I can tell a difference between the two.

I like it better than Redline so far

Kevin, just for grins I tried a speed shift from 5th to 6th and found it pretty smooth, tho I do not recommend this to everyone

I will stay with Bel Ray simply because it is very easy to identify if there is a trans leak.

Bel Ray was our go to lube for years, very good products for sure, there engine oil gets high marks from Bob The Oil Guy

I like the new heavy fluid as well.

I used BelRay for 10 years or so and have been using Redline for the last 5 years and they are both excellent.

I've had good luck with Shaeffers transmission fluid. Used to use BelRay but IMHO Shaeffers is better for me.

Brad Penn is good oil too

After years of various brands I’ve settled on Amsoil and their specific fluids for the three holes and their oil filters. Joining their preferred customer program is inexpensive and offers significant discounts and free shipping is easy to obtain. Saves time and frustration of seeking specific products and is very competitive.

That's pretty amazing. HD, for all the complaints they get (and some are warranted), the last few years they have been getting some things very right.
Looks like this fluid is one of them.

Personally I run Syn 3 in engine , HD gear oil in Primary and trans . Engine oil changed every 2500k primary every 5 k and trans every 10k .
Most important things are using oil for air cooled MC , keeping it at proper level and changing it regular
