clean out the screen where the lock up solenoid and od solenoid are bolt to the valve body...the solenoid has to be unbolted from the valve body.

if the converter went bad and dumped crap into the fluid..that screen will plug..and the converter lock up will not disengage..

dont ask how i know..but something to look at.
