Where is the gauging setup first placed?

On the machined surface of the transmission case with no gasket, with the bridge legs' short ends down and the gauging cylinder resting on the center machined surface of the rear internal gear, locked with a thumbscrew.

How is the end play gap actually measured?

After moving the bridge, gauging cylinder, and plunger onto the converter housing and letting the plunger rest on the inner bearing race of the output shaft, a feeler gauge is used to measure the gap between the gauging cylinder and the shoulder of the gauging plunger.

What must be removed before measuring at the converter housing?

The output shaft end play adjusting shim at the end of the output shaft must be removed (step 3).

This scanned service manual page, headed "ASSEMBLY," documents part of an automatic transmission assembly procedure — specifically step 24, adjusting output shaft end play after setting output shaft bearing preload. The procedure uses special service tools: J 34291-1 (bridge), J 34291-2 (legs), J 34291-5 (gauging cylinder), and J 34291-6 (output shaft end-play gauging plunger). Sub-steps instruct the technician to (1) set the bridge, legs, and gauging cylinder on the machined surface of the transmission case (no gasket) with the gauging cylinder resting on the rear internal gear, (2) insert and lock the gauging plunger, (3) remove the output shaft end play adjusting shim from the end of the output shaft, (4) transfer the bridge, gauging cylinder, and plunger to the converter housing machined surface with the plunger resting on the inner bearing race of the output shaft, and (5) use a feeler gauge to measure the gap between the gauging cylinder and the shoulder of the gauging plunger. Four illustrations (labeled SAT506A, SAT507A, SAT508A, and an unlabeled one) show tool placement on the transmission case, the adjusting shim removal, converter housing setup, and feeler gauge measurement.
