I have been looking but I figure I might get a quicker answer here.

I want to change my Tranny fluid and rear diff fluid to Royal Purple how many Quarts will it take for each? Anyone done that yet?

I would go with Redline MT90 for the tranny fluid. Good reviews.

Royal purple had no significant better shifting if any,(the factory felt better)
As far as the quantity, check you owners manual.
