i have a TH-400 for sale along with a jw bellhousing for a modmotor and a flexplate also. i bought it off of another site and never ran it in the car staying 6 speed for a while longer. below is a description of whats done to the trans. pm me if there are any questions.
Built TH400 with JW bell and flexplate. Trans has HD sprag, shaft, planetary change, reverse manual valve body and trans brake. Also includes a new pan. Trans has zero passes since freshened. Was behind a BBC with roots in a pickup running mid 5s... Your Modular is not going to break this trans. I had bell on trans cut and JW bell installed. Since it was taken apart to be cut it was freshened.
$1000+ shipping takes it
