Pep Boys and AutoZone say use: only Mercon 5 or something bad will happen.
I ran into a guy I know who does only performance automatic transmission work and he said: do not use Mercon 5 or something bad will happen. His claim was: use only ATF. And he gave me a case of NAPA "Premium Performance ATF".
Now the both of them Cannot be right - so what say you all? <g>
