Doing the first service and want to use Mobil 1 for the transmission. I see gear oil on their site but it doesn't mention anything about motorcycles.

Is this the right stuff? Just want to make sure.

yup,, but you would be better off with redline shock proof

I use the Mobil1 75-90 in my transmission.

 

Thanks Pete, Redline? Don't make me go back and read all the oil threads again, my brain can't handle it [8D]. I looked at the polls and Mobil 1 was up there at the top so I figure I'll go with it.

 

I have emailed Redline 3 times now asking for the viscosity of "Shockproof" with no reply. It is not on the bottle. How do I prove I used the recommended viscosity if I have a warranty issue?

 

M1 75w-90 is what I have in mine, and I aint blowed it up yet

 

75w-90 is fine but Redline V-Twin Trans Fluid is 75W-140 and Spectro 6-speed Trans Fluid especially made for H-D 6 Speed Trans is 75W-140. I use 75W-140 Mobil1. The 75w-90 Mobil1 should be fine as long as it meets GL-5 standards. Try the 75W-140 and see how nice it shifts. Won't hurt to try it.

 

It's good............. I am using M1 LS 75w-140 Super Syn in mine, and it's very quiet and shifts smoooooooooth. The **** is $17 a qt, though.

Redline is in my fatboy, mobil 1 in the sproty. 6 of one half dozen of the other.

 

+1 on the Spectra 6 speed 75w140. Best trans oil I have ever used.
