GEARSHIFT CROSSOVER CABLE
Before replacing the gearshift cables for a hard-
shifting complaint, disconnect both cables at the
transaxle. Then, from the driver's seat, manually
operate the gearshift lever through all gear ranges. If
the gearshift lever moves smoothly, the cable(s)
should NOT be replaced. If the gear lever binds
replace the cable that is causing the binding condi-
tion. If the problem still exists, check the crossover
cable adjustment (Fig. 218).
(1) Working over the left front fender, remove the
auxiliary vent from the selector shaft housing (Fig.
219).
(2) Locate the gearshift lock pin that has been
included in the new vehicle packet located in the
glove box.
(3) Place transaxle gearshift in the neutral posi-
tion.
(4) Insert lock pin (so long end is down) into same
threaded hole (Fig. 220). A hole in the selector shaft
will align with the lock pin, allowing the lock pin to
be screwed into the housing. This operation locks the
selector shaft in the 3-4 neutral position.
(5) Remove gearshift knob (Fig. 221).
(6) Remove gearshift boot (Fig. 222).
(7) Remove gearshift console screws and remove
the console (Fig. 223).(8) Loosen crossover cable adjustment screw.
(9) Verify gearshift mechanism is in the neutral
position.
CAUTION: Be sure crossover bellcrank does NOT
move when tightening adjusting screw.

BEARING ADJUSTMENT PROCEDURE
The A-598 (T-750) transaxle has two bearing
adjustment procedures that must be performed if the
transaxle case or related components have been
replaced. If the intermediate shaft, and/or bearing
cups and cones have been replaced, you must per-
form the intermediate shaft preload shim adjust-
ment. If the differential case, cups or cones have
