This is what it ran , how much is left in it

I still thing you have a junk converter but shake down what you have first, aka find out what it likes, RPM, timing, launch rpm excetra. By the time your half way threw it all.......you will know if it is the transmission or the converter. because if it is the transmission failing it won't last thru a half a dozen run. but iF it is the converter, it will.
save you money, Don't by a converter and DON'T buy a "off the shelf" converter.............well..........If your converter is slipping as bad as it sound.........and "off the shelf converter" will work much better............

Force yourself to shift at 5- 5500 and then raise it 200 rpm at a time. until it kick you in the pant or the ET slows.
