Hey everybody, I've been trying to change the fluid in my '89 4.0 5-speed for about a week now. Started off getting interrupted by surprise storms, then realized I didn't have a 15/16" wrench so I ordered one, then realized I've got a seriously stuck fill plug and it looks like the previous owner lent it to a teething baby 'cause it's all kinds of chewed up. Couldn't get it off with the 15/16" and started doing some research. Been soaking it in a little WD-40 but I'm about to go pick up some PB Blaster. Saw a few mentions of trying a pipe wrench, but that didn't work. Also saw mention of hitting it with a torch but haven't tried that yet. So my question, and I'm hoping it's a very stupid and unnecessary one but it probably can't hurt to ask... Righty tighty, lefty loosey, correct? Been trying to remove the plug in the direction I'd expect it to loosen, but I'm going to feel like a real idiot if this thing is threaded the other way for some reason. Also should mention that I haven't drained the fluid so I'm not in a position where I've had to pull the shifter and fill it that way, and the truck shifts fine, but I bought it last month and I have no idea when it was last changed so I'd sure like to get it done. Thanks in advance!
