Hey, John;

The most important thing is to keep the oil level up. There's two plugs on the back of the transmission: one on the top right and one on the bottom left. By the book, the oil level is supposed to start to run out of the lower plug when the transmission's full. Use Dexron III automatic transmission fluid if you can still find it. Sometimes the lower plunger seals will start to leak so it's a good idea to check the fluid often. I've found that the seals are prone to leaking if the machine sits for a long time (years) and then gets a lot of use.

The bands will need adjusting sometimes, too, but the manual would probably show you how better than I could explain. I think I have a copy on the '72 manual scanned and I'll see if I can find it and send it to Mike. Maybe he'd like to post it on the site?

Hi everyone, I am John (eyewatchjb), thanks for the chance to join your group.

I was reading the maintance fluid level transmission "By the book, the oil level is supposed to start to run out of the lower plug when the transmission's full. Use Dexron III ", I though the transmission was full if it ran out the top hole so I filled it to the top hole, after reading your information I drained the oil from the bottom hole.
I have lost my manual for Max II 1992 so I don't know what to do, any help would be wonderful.

Hi John, welcome to 6x6 world. As for the T-20, it sounds like you have everything right now. Just like Don said use Dexron III and fill it until fluid runs out of the bottom hole. Was there anything else that you were unsure of?

Thanks Mike: is that the same hole you drain the transmission from to.
Anyone have a manual for MaxII 1992 that maybe they could e-mail it to me.

I used to have a MaxII and some damm drugies burned it on me because they had a grow up on my property in the country, the mounties flew over and found it, they blamed me . That was 3 years ago, my friend had one and this year he sold it to me but now I don't have a manual, lost somewhere's in my junk room.

Yes, one quart and check out this thread for adjusting the T20: http://www.6x6world.com/forums/trans...-20-setup.html

I talked to Jay at RI on Thursday. They recommend Type F and limited slip additive. 4 oz additive + 28 oz Type F = 1 quart. I guess alot depends on how much you can get out of it.

Thanks guys for the right amount of transmission fuild.

I am following the setup for an adjusted transmissiion but ran into a snag when I went to adjust the bottom blots, they will not turn, their is no trouble
with the top blots I can adjust them with my fingers.

Anyone with an ideas, I have been puting wd-40 on them all afternoon but no luck.
