What should I be careful about when removing the output shaft from the transaxle?

Two cautions are given: when tapping the output shaft, hold the front cover so it does not fall, and an adjusting shim is attached to the rear internal gear side of the output shaft, so be careful not to lose it.

What is removed together with the front cover?

The output shaft is tapped and then removed together with the front cover (step 18), after the front cover retaining bolts are removed (step 17).

This is page AT-18 from a factory service manual's automatic transaxle Disassembly section, uploaded to a 1990 Nissan Micra gallery. It covers steps 15 through 21 of the disassembly procedure. Step 15 instructs straightening a lock washer (with an inset showing where to bend it). Step 16 covers removing the idler gear bolt and lock washer, and step 17 removing the front cover retaining bolts. Step 18 describes tapping the output shaft and removing it together with the front cover, with two cautions: (a) hold the front cover while tapping so it does not fall, and (b) an adjusting shim is attached to the rear internal gear side of the output shaft and must not be lost. Step 19 is removal of the front cover gasket; step 20 covers removing the idler gear, idler gear shaft, and taper roller bearings by tapping the idler gear shaft with a suitable drift; and step 21 is removal of the seal bushing. Each step is accompanied by a line-art illustration referenced by figure codes SAT263 through SAT268. No torque values, part numbers, or model/year applicability statements appear on this page.
