Are you sure the TV ( trans shift cable at the throttle valve) cable is correctly adjusted?? Without line pressure readings, I can only guess that the D3/Part throttle check ball is missing, if it is a trans problem
If the TV is correct, I am assuming that the TV cable is pulled tight at WOT.
Did you check the throttle (ACCEL) cable to be sure that the carb goes wide open when your accel pedal is on the floor?? This must be done with someone in the car and a second person looking at the carb. Without doing this, you do not know if you have WOT. Without WOT, the trans will not de-tent and shift down.

SOURCE: i need to adjust the tickover on my volkswagon

idle speed is not adjustable, it is controlled electronicly by the ECU powering a motorised butterfly valve or throttle plate. You didnt say what the problem is. poor idling/cutting out on idle? This somtimes can be cured by cleaning the throttle body and butterfly, but this will then have to have its basic settings performed by a plug in diagnostic machine.

Passing gear is not working


aka> passing, kickdown and TV cable failure.
which transmission?
30 or
32RH?
Kick down happens on all transmissions this way.
1:kick cable. (and or vacuum modulator, Hill)
2: TCM brain does all that magic. (PCM data (load, rpm,etc)
and some early years, are 1/2 and 1/2 , yes.
ill look up yours now to see which.
i look at FSM page 75+
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

shows it has a Governor, so if it fibs about trail speed, sure no passing gear.
ok page 87 shows TV cable.

page 90 lists the causes. read that?
transmission must not slip, does it, flogged up hills?

TV cable dead, or adjusted wrong. end to end, and detent valve at trans case. must move full range.
gov, failure (or line pressures excessive)
coke bottle under throttle, nah
valve body issues aplenty.

this car has no TCM
only a signal, TCC lockup wire from PCM to clutch lock sol.
so , its a 100% Hydramatic trans, with NO BRAIN box.

my guess, is the KICK cable is DEAD> or set wrong.

aka, kick down cable.

Transmission not shifting up speed sensor problem?


Your Transmission is not electronic so its not the speed sensor . Your transmission uses engine vacuum and cable to determine when to shift. You need to check for engine vacuum at the modulator on the side of the trans it is a small steel tube with a rubber hose at the end. Also you have a throttle cable that is connected at the throttle body and goes to the trans if this cable is stuck it will delay the up shift. Get a good service manual and it will directions on how to adjust the cable and some more troubleshooting steps.

When driving the transmission shifts to soon doesnt let the car gain speed


sounds like the throttle valve (TV) cable is adjusted wrong. Proper adjustment procedure: with engine warm and turned off find the adjuster fo TV cable. the cable is the one hooked to the bottom of the throttle lever on the carb, follow it back to the bracket, there will be a metal tab on top of the cable, depress this tab and push the black part of the cable where the wire comes out, toward the rear of the car, it should go all the way in. Now grab the throttle lever on the top where the throttle cable hooks up and push it wide open, it will be difficult, and you will hear some clicking from the TV cable bracket, once you get it wide open just release the throttle and the adjustment is done. If it does not shift correctly now have a trans shop look at it, as the TV cable is the only adjustment on this trans. All this info is assuming you have an overdrive trans, either 200r4 or 700r4.

Throttle cables???


it controls the shifting of the trans. it is important to have this adjusted correctly. I dont remeber the exact procedure but I do know that when it is all said and done, you end up with only a slight bit of slack on the trans cable.

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.
