To change the fluid, run the engine at least 4 minutes or until the engine and Trans. have reached
 operating Temp. then raise the car, and rotate the engine until one of the torque converter drain
 plugs is in line with the hole in the housing and remove the brass plug with a 3/8" (it could be 
a 7/16") X 1/4" drive socket which should be small enough to fit through the hole. Though I have
 done it with one plug removed, the Manual says to then quickly rotate the engine again 180 degrees
 and remove the OTHER plug to allow air to enter, then you will be able to completely drain the 
converter, a feat not possible on most newer Trans.

Then remove the drain plug in the Trans. oil pan and drain the main case completely and replace the
 three drain plugs, replacing the gasket on the pan drain plug.

To refill, just roll back the right side carpet to expose the cover on the center tunnel of the
 floor and remove it, remove the filler cap/dipstick and install the first three Quarts of Type
 F, (second choice FA) or if not available, the Dextron II(*) or whatever the latest replacement 
is, do NOT use any of today's Type "A" which WAS the preferred fluid IN THE DAY.

Apply the Parking Brake AND foot Brake and start the engine and place in neutral, and be sure to
 set the idle as low as possible as it will splash around and even out with too much RPM while
 the cap/dipstick is off! While idling the engine, pour 4 more quarts into the Trans. and run the
 gear selector through all of the positions slowly, check the oil level by installing the cap and
 turning it to the stop, and removing it to read the level, add enough fluid to reach the full 
mark. I would have about 10 Qts. on hand, as it does not say how many are needed. ...Whew! Next
 time, BUY THE MANUAL! It's due again in 15,000 miles!

This IS a Detroit Gear Division of Borg Warner 3 Band DG-200 Studebaker Automatic Drive, developed
 specifically by and for Studebaker Corp. by Detroit Gear AND Studebaker Engineers. Much later 
units were slightly modified and sold to Jaguar and others.

(*) Dexron III-Mercon works fine/ED.
