Thanks dudes!

According to my Chiltons,  3 pints.

Fill it to the bottom of the fill hole and install the plug.

Fill it to the bottom of the fill hole and install the plug.

Just make sure the trans is level.

Sorry John I just had to add that, seen too many over and under filled Munices because they were not level on fill.

Hey guys, thank you for the info.

I am curious though. How close to 3 pints is used when filling the Muncie using the "fill 'till it runs out of the hole while trans is level" method?


thanks for help on this..

About 2-1/2 pints.
