Looking at the Redline MTL

Red Line (50204) SAE 75W80 API GL-4 Manual Transmission and Transaxle Lubricant..
Is this the proper wt. for the NV3550?

Thank you,
 
Redline MTL is the most common recommendation, followed by Royal Purple Synchromax. I've used both and liked RP better. Shifting felt smoother.
 
I've used Redline and RP. Got RP in mine now. Couldn't tell the difference between the two.
