B&M 80706 PRO STICK SHIFTER - Manual (Page 3)

slight changes between GM 4 speed transmission gears.
The 4L80E and 4L85E transmission detent spring might not
fully seat in low gear and the swivel will not slide in and out of
the hole of the selector lever freely in low gear. This is nor-
mal! and will not affect shifting as long as the cable is ad-
justed and the slight gap between the transmission detent
spring and the selector rooster comb is kept to a
minimum.(See Figure #4)
Leave the swivel out of the hole and move the selector lever
to Park, all the way forward. Also move the shifter to the Park
position (all the way forward). Reinsert the swivel into the
front hole in the selector lever. Check to see that the swivel
will slide freely in and out of the front hole in the selector lever
in this position. If it does not slip in freely, adjust the swivel
slightly until it will slip into the hole in the lever.
Move the shifter back to the Low gear position and check that
the swivel will still slide easily in and out of the front hole in
the selector level. (If you do not use the front hole in the lever,
it will be impossible to correctly adjust the cable.) Operate
the shifter through all the gear positions. Check to make
sure the swivel will slide in and out of the front selector lever
hole in each gear position. The shift cable is now correctly
adjusted. Install the cotter key supplied with the shifter into
the swivel and spread the key ends.
If you have a problem, DO NOT FORCE THE SHIFTER, this will
damage the cable, the shifter or the transmission. Simply
start at the beginning and carefully check all your steps.
Step 12. On GM vehicles the neutral safety switch may be
located on the shifter (steering column or console), or it may
be a mechanical interlock in the steering column that pre-
vents the key from turning to the Start position unless the
