royal purple shows its benefits more in pushrod applications because of the super high zinc content. you're better off going with castrol edge titanium, shell platinum, or mobil 1 for the money. Royal purple shouldn't have any adverse effects on your engine though, trannys going bad "because of royal purple" were probably trannys that were shit anyways and would've went bad regardless, or were over worked.
