Step 9: Make sure that the shifter and the transmission are both in the Park position.
Remove the first 5/8"-18 jam nut (15/16" wrench size) and one of the internal
tooth lock washers from the cable. Install the cable into the lower cable mounting
bracket, and then reinstall the lock washer and jam nut onto the cable.
Step 10: Make sure that the 1/4"-28 jam nuts are installed on each end of the cable. Then
install the rod ends onto the cable, threading them on approximately halfway. Do
not tighten the jam nuts against the rod ends yet.
Step 11: Attach the rod end at the transmission to the trans gear lever.
TH350 and TH400 transmissions use a 1/4"-28 x 1" button head bolt, flat washer,
and nylock nut. The rod end attaches to the outside of the trans gear lever, away
from the transmission. The button head bolt can be installed from either direction,
but make sure the rod end is sandwiched between the flat washer and the trans
gear lever. Fig. 11 & 12
700-R4, 200-4R, and 4L60 transmissions use a 1/4"-28 x 1" flat head bolt, flat
washer, and nylock nut. The flat head bolt is installed from the inside of the trans
gear lever, and the rod end attaches to the outside of the trans gear lever, away
from the transmission. Make sure the rod end is sandwiched between the flat
washer and the trans gear lever. Fig. 11 & 13
Step 7: Make sure the transmission is in Park by rotating the original trans gear lever
clockwise as far as it will go. Remove the original nut and trans gear lever
from the transmission selector shaft. Remove the rod end from the new trans
gear lever, and then install the new trans gear lever onto the selector shaft,
pointed down and towards the front.
NOTE: 700-R4, 200-4R, 4L60, and 4L60E trans gear levers must be
installed so the trans gear lever is in the furthest forward position. Fig. 8 This
is so that the cable will have full travel. The bolt hole in the trans gear lever
on the 700-R4, 200-4R, and 4L60 transmissions is chamfered on one side.
The chamfered side must face towards the transmission. This is required for
clearance from the oil pan when the transmission is in low and second gears.
Secure the new trans gear lever with your original nut. Fig. 9
Step 8: Install the lower cable mounting bracket on the left side of the transmission
pan, using the provided longer bolts, lock washers, flat washers, and 3/8"
spacers. Most TH350 and TH400 transmissions use standard thread bolts
(5/16"-18 x 1-1/4"). 700-R4, 200-4R, 4L60, and 4L60E transmissions use
metric bolts (M8 x 30mm). The TH350 uses the two rearmost pan bolts on
the left side, and TH400, 700-R4, 200-4R, 4L60, and 4L60E use the two
pan bolts directly behind the selector shaft. Fig. 10
Step 11: (continued) 4L60E transmissions use a 1/4"-28 x 1" button head bolt, a 1/8"
spacer, a flat washer, and a nylock nut. The rod end attaches to the inside of
the trans gear lever, towards the transmission. The 1/8" spacer goes between
the rod end and the trans gear lever. The button head bolt can be installed
from either direction, but make sure the rod end is sandwiched between the
flat washer and the spacer. Fig. 11 & 14
Step 12: Route the cable up to the shifter and attach the other rod end to the quad
arm using a 1/4"-28 x 1" button head bolt, flat washer, and nylock nut.
Fig. 15 The button head bolt can be installed from either direction, but
make sure the rod end is sandwiched between the quad arm and the flat
washer. When routing the cable, make sure that it is not touching the
exhaust or any moving parts. The cable should be routed as smoothly as
possible without any sharp bends.
Step 13: Position the upper cable mounting bracket up against the bottom of the floor
and next to the cable, aligned with the retaining groove on the cable. Align
the upper cable mounting bracket with the quad arm, where the cable can
push and pull in a smooth motion. The location of the upper cable mounting
bracket is an important factor in how smoothly the shifter operates, so make sure
it is aligned correctly.
