Hey everyone so just bought a 72 lemans and got it running . Went to check the Trans fluid level and it was dry . Ended up filling it with mostly atf +4 ... A friend said it would be fine . Now after reading I'm wondering if I need to replace it with some dex/merc gm atf. Does that mean I have to drop the pan or is there a drain hole ? Or can I just keep it ? Haven't driven it yet but had it idling for a little in park while I filled it
