X 2.

I can get 11 quarts out if I let it sit for at least 24 hours. I haven't switched to Transynd because I can get a case of Dexron iii for $20 at Costco.

I do my own changes so it's cheap and easy.

When I did my old class A. The trans took about 10 qts.
When you remove the trans filter. DO NOT LOOSE the MAGNETIC WASHERS. Clean them and replace them on the stud.

Allison cautions that you NEVER use the flush type of fluid change. NAPA sells a filter for the Allison 1000 and the screw on Allison filter is also available from numerous sources online.
They have a shallow and a deep pan which can affect the overall capacity of your transmission. Total capacity is 13-15 quarts. The best way is to measure what you take out so that you do not over or under fill your transmission.
