You will also want to inspect the torque converter mounting lugs for damage.
Install manual valve and detent spring. This may be causing the piston to stick in the bore. I appreciate the information found on this page. To reassemble, reverse disassembly procedure. Install oil strainer, pressure relief valve and solenoids as applicable.
