I run Spectro in all 3 holes on mine. I have thought about Redline Shockproof in the Tranny tho to see if quiets the shifting a little better, is only in first that I really notice it. Otherwise I have no complaints and plan to run Spectro next oil change, plan to just do all 3 when i hit another 5k, have about 2,500 to go.

I have Redline Shockproof in the gearbox and Redline Primary in the, uh... Primary.
The combination of the two gives me very slick gearshifts (better than Formula+, Vavoline, or Motul alternatives).

Why change transmission oil every 10K miles when the recommended maintenance schedule is 20K? If you were using some cheap off-brand stuff I could possibly see it. Do you use premium grade engine oil and change it every 2500 miles, or change your primary oil every 5K? Just askin'.

baker use to recommend redline, i don't know why they now recommend spectro? i'm thinking spectro made some kind of deal with baker would be my guess. i think if you call baker they will tell you they like redline.

I switched from Spectro to Red Line trans fluid recently both are darn good. But IMO the Red Line is somewhat easier shifting...time will tell... I change trans fluid once a year or 15k which ever comes first.
