13. The two transmission pan bolts
could be either Metric thread
or American thread. You will
need to purchase two bolts
1/4” longer than the two that
you removed. Spacers need
to be placed between the bracket and the transmission pan with the
two longer bolts holding it all together in the holes of the bracket as
shown.
14. Install the transmission shift
lever so that the squared end
is closest to the front of the
vehicle. Add the washer and
the nut to hold it in place.
15. Take the small nut, two rubber boots and tone large nut and washer
off the transmission end of the cable. Insert the cable into the bracket.
Reinstall the large washer and nut and two boots. Rotate the shift
lever clockwise to the park position. Now you are going to put the
swivel onto the threaded end of the cable and turn it until it lines up
with the middle hole of the shift lever. Install the cotter pin. If it needs
more travel, loosen the large nuts and washers and move the cable
forward or backward to gain more travel. Then retighten the large
nuts and washers. Install the small nut and tighten.
16. Try to shift the column. You may experience a tight pattern, if so
loosen the clamp around the column. This should allow the column to
move easier. If not, check that cable is in alignment from the bracket
to the lever.
