Top:
In an alternating fashion, knock each weight against the bolt head to free the pump. If no slide hammers are available, use a screwdriver or other prying device to wedge between the sun gear shell and the front clutch retainer or to tap on the rear side of the pump.
Middle Left:
The torque converter has an impeller integral in the housing, front cover, turbine, stator, ring gear, and, if it’s a lock-up unit, a clutch and apply piston. This is a truck A-727 low-stall lock-up version.
Middle Right:
The low-reverse drum still inside the low-reverse band is splined to the inner race of the overrunning clutch. Slide the drum out; it may also pull the overrunning clutch inner race with it.
Bottom:
TorqueFlites were found in some of the best and most unique muscle cars. This 1970 AAR Cuda 340 6-barrel automatic (with TA Challenger engine notation decals) has only 34,000 miles on the original A-727.
