M21 Oil Weight/Brand Recommendation

What ever you do -- DO NOT run ATF in a Boggie Woggie or a Munchie ... some ( I think MoPar) used to recommend ATF.

The TAZ

Some of the Tremecs use ATF [img]<<GRAEMLIN_URL>>/dunno.gif[/img]

The GL4 is for the Muncies and Borg Warners etc. It has to do with the &quot;yellow metals&quot; in the transmission. The newer transmissions like the Tremec call for the ATF which is a GL5 oil.

I sell a lot of this GL4 AMSOIL to hotrodders locally as well as the Cummins truck guys using the NV4500 transmission. I swapped it into my stuff a few years ago and noticed a big difference. I am a dealer and will be happy to help if anyone needs some shipped or you can just use my referral # 2011844 to knock a few bucks off the price.

Regular tap water. has a few more minerals in it for lubrication. Alot of trans guys do not like synthetic gear lube in the old cars. Atleast that is what they tell me.
