Default Transmission Fluid ??

2000 FLT Twin Cam---- I use Mobil V twin motor oil and Red Line Heavy Shock Proof Gear Oil in the Primary case . Can I use this in the transmission as well? Or is there something better?

I wouldn't put gear oil in your transmission.

the Redline Heavy Duty Shockproof IS for the transmission, NOT the primary. Redline does make a primary fluid.

I used Mobil1 VTwin motor oil, Redline Heavy Duty Shockproof in the trans, and Mobil1 synthetic ATF in the primary.
