That's going to depend on whether or not you have any coolers, what size pan
is on there, as well as a few other variables. I'd have at least 12 quarts
on hand. (This is from personal experience on a 47RE and 48RE... if you
really have a 727, i.e. 3spd, no overdrive, then you'll probably use a
little less. It never hurts to have a couple extra quarts of ATF on-hand,
though)
> what type of fluid is best
Best is probably ATF+4 - however, ATF+3 will work fine, and will be cheaper.
Do not use any fluid that isn't rated as Mopar 7176 compatible (such as
Dexron II, Dexron III, or Mercon).
> and do I have to prefill the torque converter?
Always - pour a quart into the converter, and put a thin film of petroleum
jelly (Vaseline) around the snout, so you don't damage the front seal when
installing it.

Dexron is the fluid originally recommended in the 727, using it won't cause
any harm.
The plus fluids are intended for use in transmissions that have lockup
converters and/or overdrive.

Wouldn't that depend on what year that transmission is and the OP did not
say? My 79 used Dextron II and it specified a Dextron type in the manual
(both the FSM and the owners).

Yeah... I'm stuck in post-90ish mode.

Either that or I'm just showing my age :-)
