What year models does this shift kit fit?

The document states "This kit doesn't fit 1979 to 82 model," and includes instructions for the "83 up 3-4 Shift Valve and Bushing," so it applies to 1983-and-later transmissions.

How is the Governor Limit Valve installed?

Install the O'ring, then install the 3/16 steel ball, the small ORANGE spring, and finally a cotter pin to hold the spring.

Should the TM valve be removed during this procedure?

No. The callout says the TM valve bottoms in the bore and it is "best not to remove it." The TM valve is reused.

What trick is suggested for changing the 3-4 valve?

Use a cotton swab stick as a wedge in the indicated area of the valve body while changing the 3-4 valve.

How is the Type 2 plug installed?

The Type 2 plug has a hole in both ends; install it hollow end outboard with the O'ring in the outboard groove.

This is a scanned page from an automatic transmission valve body service/shift-kit instruction sheet, photographed 15 June 03. The left side shows a photo of a valve body separator plate/casting with two callouts: one indicating where the TM valve bottoms ("Best not to remove it") and one advising the use of a cotton swab stick as a wedge while changing the 3-4 valve. The right side contains illustrated steps: a plug note (Type 2 has a hole in both ends; install hollow end outboard with the O-ring in the outboard groove), step C showing the TV Limit Valve with an ORANGE spring, and step D covering installation of the new 3-4 Shift Valve and Governor Limit Valve. Step D identifies WHITE and RED springs, reuse of the TM valve, the 3-4 valve, an O-ring, and instructions for the Gov Limit Valve: install the O-ring, a 3/16 steel ball, the small ORANGE spring, then a cotter pin to hold the spring. A note states the kit does not fit 1979 to 82 models; a further section (partially cut off) begins instructions for the '83-up 3-4 shift valve and bushing, directing removal and discard of the original 3-4 valve.
