FSM says 15 1/2 to 18 1/2 pts. Which is it? Have a Moroso deep pan, there's a 2 quart add on, plus the #6 lines to radiator and then a small remote cooler in front of the radiator. I have one qt in the converter already. My question is really about the FSM quantity.
 
Im thinking you will be at around 13/14 quarts with the deep pan.
 
The convertor is the big variable.. Stock the was 10 3/4" & 11 3/4"convertors small convertor = less fluid... There's your 1.5 quart difference... Deep pan = more fluid...
 
Thank you for your answers. So I believe that I will probably end up in the 10 1/2 to 11 1/2 qt area. Will try 11 or 11 1/2 qts for the start up, and check it as soon as it will idle. This is all new for me, just swapped out a 4-speed. New Hemi build, so there's going to be alot going on all at the same time. Pan has drain plug if I go over.
Thank you again.
Dadsbee, you need a cup of Mouse milk!
You are probably the only one here besides me that knows what that is! lol.
May you always have favorable tail winds.
 
If you have 1 quart in the converter, I'd put in another six quarts, fire it up to circulate it thru the trans, converter, cooler and lines.
Shut it off after a minute or so and check the dipstick. Add I qt at a time , refire, until the level shows on the dipstick.

Supposed to be checked hot, idling in neutral. :drinks:
 
I have about 21 pts in it. When I fire it, it will be on jack stands. The trans has been dyno tested, will keep a close eye on it.
Thanks again everyone!
