need help ID'ing tci transmission

Take a pic of the valve body. TCI RMVB separator plate is usually red with a stamped number 121700. The kickdown valve directly next to the manual valve would be disabled, meaning the throttle pressure cam surface would not push in the kickdown valve.

Open attachment 220000 and scroll to page 9, FIG 24, STEP 27. There would be a large clearance where the 1/8" drill bit is shown and the valve stem protruding from the valve casting would not have any spring action.

On page 7, FIG 17, throttle pressure spring and kickdown valve positions are swapped to provide MAX line pressure at all times, and no kickdown linkage is required.
