Mercon V vs. ???

[88Racing]

The specs call for mercon v to be in our trucks.
There are alot of mfgrs out there that make the mercon v.
Lucas.
Amsoils.
Redline.
Royal purple.
Vavoline.
Motorcraft.
Penzoil.
Castroil.
The list goes on...........
Extra capacity pan?...Nice.... But the only benefit I see is that you get a drain plug in the pan. The pan still has to be removed each time to get at the filter but the plug makes it less messy. The key to keeping everything going in your tranny is keeping it cool...approx 160* F to 210* F.
You'll never get all the fluid out unless you drain the tq converter.....good luck ours don't have a drain plug in them.
You'll never get all the old fluid out of the transmission, the only way is to mechanically take it out and tear it apart.
