i have been searching for a procedure that explains how to set the throttle position sensor on the side of the ip however i cannot seem to locate a reference to it in the tms or haynes manuals either the diesel manual or the chevy truck manual. does anyone have a clue where to find the procedure? would greatly appreciate it.

Removal and replacement is covered in TM 9-2320-289-34, Chapter 3-46. 3 pages. Also in the -20, Chapter 3-21.1

BTW, I have new valves for sale in the classifieds( CUCV Vacuum Valves ), I include a copy of the TM pages, and a home made gage block, used to set it correctly.

Also, Warthog has posted a great thread on how to adjust the valve, here on SS. CUCV Throttle Vacuum Valve Adjustment

Be sure to check or replace all your rubber vacuum hoses, if you are having inconsistent shifting. Also, after setting the vacuum valve, if your shifting is still inconsistent, you may need to replace your modulator valve, on the transmission.

These trucks should shift as smooth as any other normal vehicle.

vacuum lines and modulator have been replaced as well as alll metal lines cleaned out with air pressure and carb cleaner truck hits shift points about right and it jerks very slightly so i think i have it dialed in. i was more just curious if adjustment of the vacuum valve (what i thought was tps) would change anything as far as get up and go. i have nobody near as far as i know to check my truck against as far as how they are supposed to run and operate normally. this is my first diesel truck so unsure exactly how its supposed to run and accelerate.
