Vacum Transmission removal

[garretttpe]

Hi All

Is it possible to remove all the fluid from a T20 using a vacuum canister? I did it today and only got about a cup of transmission fluid out. I know it leaks some which is strange as after the rebuild it sat on my tool box for months before I installed it and there were zero leaks and after 23 hrs it is wet in the bottom of the tub.

thanks

I vacume them out with 1/4"tube pushed until it hits a rib in the bottom of the case. I've for example down after this and only find a couple ounces at the most. How much did your take to fill to the bottom plug?
