Safe to put in Mercon V in A833?

Johnny Dart said

You want to use a GL4 in your 833, which is designed for soft brass syncros, which the 833 has.
Put in some Redline MT-90 GL4, and dont look back.

Hey Johnny! Have heard this is good stuff, BUT if you're occasionally powershifting, it's too heavy and slows the shift down. Wondered if you had any input there.

Me personally.....been using GM Synchromesh. Maybe not the best .........really quick shifting. Always up for a change to better, though.
