- Place the shift lever in P.
- Loosen the 3 locknuts on the linkage trunion.
- Move the transmission lever to the P range.
- Apply a forward force of about 20 lbs. to the shift handle and tighten the
locknuts to 95 inch lbs.
- Move the shift handle to N, P, and D ranges.
Make sure that there is clearance between the select lever bracket and guide
pin. If there is no clearance, adjust the lever by adjusting the locknuts.
- Place the shift lever in P.
- Remove the shifter boot.
- Loosen the 2 locknuts on the cable at the base of the shifter.
- Raise and support the truck on jackstands.
- Move the transmission lever to the P range.
- Using a feeler gauge, turn the locknuts until there is 1mm (0.039 in.) clearance
between the forward locknut and the adjust lever.
- Tighten the rear locknut.
- Move the shift handle to N, P, and D ranges.
Make sure that there is clearance between the select lever bracket and guide
pin. If there is no clearance, adjust the lever by adjusting the locknuts.
Before the linkage is adjusted, be sure the engine idle speed and anti-stall
dashpot are properly adjusted.
- Position the transmission selector control lever in D position
and loosen the trunion bolt.
NOTE: Make sure that the shift lever detent pawl is held
against the rearward Drive detent stop during the linkage adjustment procedure.
- Position the transmission manual lever in the D position,
by moving the bellcrank lever all the way rearward, then forward 3 detents.
- With the transmission selector lever/manual lever in the D position,
apply light forward pressure to the shifter control tower arm while tightening
the trunion bolt to 12–23 ft. lbs. Forward pressure on the shifter lower
arm will ensure correct positioning within the D detent as
noted in Step 1.
After adjustment, check for Park engagement. The control lever must move
to the right when engaged in Park. Check the transmission control lever
in all detent positions with the engine running to ensure correct detent
transmission action. Readjust if necessary.
