I'm going to change the trans fluid and filter on my 98 explorer. What transmission fluid do I use for the 98 Explorer? I do not have the owners manual to look it up. I looked online and found that some used Mercon and others used Mercon V. I have a case of Mercon trans fluid in my garage, can I use Mercon? Or do I need to use Mercon V? And how many quarts do I need?
