SOURCE: HOW DO YOU ADJUST KICK DOWN CABLE FOR CHEVY 1500 1988

700R4/2004R TV Cable Adjustment Instructions WARNING! IMPORTANT NOTICE!
POST INSTALLATION ADJUSTMENT.
It is imperative that after your new TCI® 700R4/2004R transmission has been installed that the Throttle Valve (TV) Cable gets adjusted properly, DAMAGE WILL OCCUR to the transmission, voiding the warranty. If you are unsure about the proper adjustment needed, call TCI®'s tech line for help or refer to a General Motors service manual for additional information and reference.
Function of the TV Cable: Many people believe that this is a detent downshift cable and that this is the only function that the cable performs. In actuality, the TV Cable controls line pressures, shift points, part throttle downshifts and detent downshifts. The cable functions similarly to the combination vacuum modulator/cable systems found on other automatic transmissions.
TV Cable Connection: If you are retrofitting your TCI® 700R4/2004R transmission in place of a different model transmission (i.e. TH-350 or TH-400) it is imperative that you follow the TV Cable bracket fabrication instructions. If your TCI® 700R4/2004R is replacing an original 700R4/2004R then skip to Step 2.
Step 1 Obtain a cable that is designed for use with the 700R4/2004R transmission. The TH-350 and older TH-200 cables are designed differently and will not work. A salvage yard cable may work but be forewarned: There are about 30 different length cables found on stock vehicles and a cable that is too short in your application will not work. Also, used cables could have a number of problems as well, including stretched cables, damaged sheathing or housings or mutilated cable ends. TCI® recommends our universal TV Cable (TCI® 376800) that is designed to work correctly in any 700R4/2004R application.
gm_tv_fig1.gifStep 2 With the carburetor/throttle body end of the TV Cable disconnected, pull the link out of the transmission and fit the cable end to the link as shown in Figure 1. Push the TV Cable sheath into the seal in the transmission and tighten the 10mm retaining bolt. If your vehicle has a factory installed bracket for the TV Cable then skip to Step 4.
Step 3 Install a bracket that will allow the TV Cable to mount to the carburetor/throttle body. TCI® carries two brackets: TCI® 376700 works with Rochester Quadrajets, Carter AFBs or Edelbrock Performer carburetors. TCI® 376800 works with most Holley carburetors.
If you are using a Chevrolet TBI/TPI induction system, then correct brackets can be obtained from a salvage yard or a local car dealership.
Figure 2 demonstrates the correct geometry for the TV Cable mounting position. Use the following procedure to determine if your ADJUSTER MOUNTING POINT is correct.
a. Push in the Adjust Tab and retract the Slider in the direction shown in Figure 3.
b. Without allowing the Slider to move, pull the cable until it stops and measure from the mounting bracket to the cable end. Add 3/16" to this measurement and that will determine the ADJUSTER MOUNTING POINT distance at full throttle (WOT).
gm_tv_fig2.gifc. Also note in Figure 2 that the distance from the throttle shaft to the cable end is referenced. This distance must be between 1 7/64" and 1 1/8"! The cable end mounting point should follow a 78° arc between closed throttle and WOT in order to achieve the proper amount of pull on the cable.
Step 4 Adjustment of the TV Cable on a gasoline engine. For a diesel application go to Step 5.
a. Adjustments are made with the engine off. Locate the Adjust Tab on the cable housing. Press in the tab and push the slider as shown in Figure 3.
b. Release the tab and rotate the throttle lever to WOT and the cable will self adjust itself as evidenced by a few audible clicks. Release the throttle lever and check the cable for any signs of binding or sticking.
gm_tv_fig3.gifc. Road test the vehicle. Under moderate acceleration your shift points should be close to the following:
1-2…………………15-20 MPH
2-3…………………25-30 MPH
3-4…………………40-45 MPH
If the cable is adjusted too loosely your transmission will exhibit soft, stacked shifts (not spread out). DO NOT CONTINUE DRIVING VEHICLE IF THIS HAPPENS! Immediately readjust cable. If you continue to have problems, please contact TCI®'s tech department for assistance.
Step 5 Adjustments of the TV Cable on a diesel engine.
a. Adjustments are made with the engine off. If equipped with cruise control, remove the control rod.
b. Disconnect the TV Cable end from the throttle lever.
c. Loosen the locknut on the pump rod and shorten several turns.
d. Turn throttle lever to WOT and tighten the pump rod locknut.
e. Lengthen pump rod until injection pump lever contacts the full throttle stop.
f. Release the throttle lever and tighten the pump rod locknut.
g. Remove pump rod from the throttle lever.
h. Reconnect the TV Cable end to the throttle lever.
i. Press in the Adjust Tab and move Slider as shown in Figure 3.
j. Release the tab and rotate the throttle lever to WOT and the cable will self adjust itself as evidenced by a few audible clicks. Release the throttle lever and check the cable for any signs of binding or sticking.
k. Reconnect the pump rod and cruise control throttle rod, if equipped.
l. If equipped with cruise control, adjust servo throttle rod to minimum slack.
m. Road test the vehicle. Under moderate acceleration your shift points should be close to the following:
1-2…………………15-20 MPH
2-3…………………25-30 MPH
3-4…………………40-45 MPH
n. If the cable is adjusted too loosely your transmission will exhibit soft, stacked shifts (not spread out). DO NOT CONTINUE DRIVING VEHICLE IF THIS HAPPENS! Immediately readjust cable. If you continue to have problems, please contact TCI®'s tech department for assistance.

Try loosening the nut for the cable. Shift into park from under hood. Put shifter in park and pull cable, push nut towards cable and tighten nut.

Why won't my chevrolet silverado move when put in gear?


Hi, I am guessing it is an automatic transmission. Try putting the gear shift lever into a lower gear and see if it moves then. Sometimes the shift linkage gets mal-adjusted. I would also check the transmission fluid level. If it is really low, the tranny will not work either. If the fluid is really low, you'll need to look for a leak after you refill it. I am assuming that the transmission worked when you picked it up from the shop that repaired it.

I'm guessing this is an automatic. You should be able to adjust the linkage unless yours has the electronic shift on it

I'd venture to say your linkage is out of adjustment - don't mess with the bands if the transmission worked before. Move the shift lever all the way to the lowest gear detent (farthest away from Park), then tighten the linkage cable adjustment until the shifter on the transmission is right at its stop on the transmission. The shift indicator needle should be centered on the letter. (If the transmission is now working properly and the needle is still off, you can adjust the needle inside the shifter housing by sliding its clip on the bracket attached to the shift lever. I didn't say it would be easy to get at it...)

I installed a remanufactured transmission from gm. I also installed a shift indicator. My truck will not go into gear when I shift it into drive.


make sure the the adjustment for the shifter linkage is adjusted properly. if your stll having troubles, take it to your local GM service department and have inspected. If there is a internal problem with the transmssion they can fix or replaced it under the GM parts warranty the transmission comes with.

We have a Chevy 4 X 4 2003 Silverado truck, automatic transmission, and we were stranded last night because it would not shift from "Park" to another gear? Help


Your problem probably lies in the linkage, there are nylon bushings in the linkages to the tranny that get brittle and break over time.

Check your linkages, and you will probably find what I have reffered to.
