IME, the 2nd gear can be a problem...
If you redline shift from 1st to 2nd, the transmission will almost always reward you with a "scratch."
The stock gears ratio from 1st to 2nd is too wide - IMO.
When we used to hit the drag strip, I will "short-shift" from 1st to 2nd and never at redline - I will tend to hit that shift right at 6500RPM and then give it a split second longer just to not wreck the synchro.
Count me in as another disappointed Royal Purple experience...
Changed out my Redline MT-90 for Royal Purple 75W90 trans fluid, and it did not like it.
Too bad, cause David Canitz (dunno if he's still there) was a heavy proponent of Royal Purple stuff back on the big mailing list years ago.
I gotta change back to Redline MT-90...
