Default quick MT fluid change questions!

Hello,
I am going to change MT fluid with redline MT, but I have a problem.
I found the top filler hole(i believe) and it's a hax nut (looks pretty big) and I do not have any tool to open it. What kind of tool do I need to openthe top filler nut?
I checked a diagram that a member put up somewhere, and the drain plug and fluid level check hole looks different. I just want to make sure I have every required tools to change the fluid so if anybody can give me any advices, that would be great.

Thanks

I believe it is an 8mm allen socket. Use a long extension and for goodness sake, make sure you have it fully and well seated down in there before you start wrenching on it.

Have this area absolutely clean - at the filler plug...
Compressed air is a near-must..
You may have to go on a shopping excursion and buy the correct, and best tools..
Sears and Roebuck for one...

If your filler plug looks different than the level and drain plugs, then you probably have the huge hex-head filler plug that they used for a while with the first of the two synthetic oils. If so, you just need a really big socket and a couple of long extensions. It's somewhere around 22mm, but may be bigger. The standard plugs use an 8mm hex key or Allen socket, like Saaboheme said.

Yes, mine was huge!! I tried to fit the biggest socket I had, but it wasn't big enough. I guess I have to buy a socket to open it....what a waste money lol. Can I re-use the filler plug? I was going to order the proper filler plug, but since I have to spend money for a socket, maybe I can just re-use the plug??

You just need the proper sized socket and a couple of long extensions. It's nice to have a good Craftsman socket, and since they'll sell you just the size you need, it's not that expensive. If you can wait until the weekend, I can figure out what size it takes.

You can also reuse the plug without problems.

My tranny must be a pariah, but it has 6mm allen level check and drain plugs and a 15/16" hex fill plug. The 15/16" fits perfectly so it's definitely not metric. Weird...

When you're talking sizes that big, there's very little difference between the inch and millimeter sizes. 15/16" looks like it's probably about the same as 24mm, and I bet it fits a little snugger, too. We use inch sockets on the hub nuts of our cars because they fit just fine and that's what we have.
