Red Line Tranny Oil ???

Has anyone tried this lube specifically for the HD gear boxes? It's called V-Twin Transmission Oil w/ Shockproof
Quote from Redline site:

This product dampens transmission noise (reducing the notorious shifting clunk found in these gearboxes), dramatically reduces temperature, provides thicker oil films between gear teeth and resists throw-off
For all aftermarket versions like Baker, JIMS, S&S, etc.
For all H-D® trans including with Evolution engines, Twin Cam engines, and latest 6-speed Cruise Drive
Same fluid as our unique Heavy ShockProof® Gear Oil

Ive been using it for about two years on my 03 lowrider, seems to soften the so called shift clunk...heard lots of good things as far
as being a great gear lube...i will continue using it.

I ran it for a while, but wanted to get something I could pick up locally... so switched to Mobile 75-140 synthetic. Other than that, it was fine.

I use it. It is the same as their shockproof heavy gear oil 75w250. You can easily run it 20,000 miles. Great stuff.

I tried the red line for about 5000 miles, but wasnt too impressed. Just threw in the HD formula + and the tranny's never shifted smoother

I have Amsoil in my '07 Bob and it is far and away better than the Redline
Shockproof I bought for it and my '09 Softail. I have the Redline in the Softail
now and just as soon as it is time to change, out it will come. I am glad I
didn't put it in my StreetBob.

I too was suprised by the Redline Shockproof. I have had it in for 4,500 miles and the transmission shifts and "clunks" the same as it did when I have the HD Syn3 20W-50 in it. Next I will try the Amsoil 75W-140 in my transmission as I have already purchased it.

I ran it for years and also switched to the Mobil1 75/140 and like it better. That and ATF in the primary works great.

I run AMSOIL 75w140 in my trans and I got it for my buddy that has a 93 FXR and was missing 5th in the heat (popping out of 5th). When he put the AMSOIL 75w140 it stayed in 5th. In the engine I run 20/50 v twin by AMSOIL and 10/30 in the primary. So far I like it. A lot less sewing machine noise, neutral very easy to find!
