700R4 & 2004R Installation Instructions
700R4 / 200-R4 Transmission Installation
PLEASE READ BEFORE INSTALLATION ON ALL TRANSMISSIONS!!
Transmission cooler and cooler lines must be COMPLETELY flushed prior to installation! Failure to do this can damage transmission and VOID warranty!
Use *Kooler Kleen* - Available at most auto part stores.
Before starting vehicle, add 5 quarts of fluid to transmission and let stand for a few minutes allowing fluid to drain into transmission. Add as many more quarts as needed then start engine and run through all gears with foot on the brake. Fill to level on stick.
**NOTE** Check / research for total amount of fluid your transmission requires to be FULL. Some transmissions drain down slower than others, so be sure your transmission if full before driving vehicle. If it is not full, damage will occur. **Add another quart or two after road test**
-REMEMBER – NOT FOLLOWING ALL MANUFACTURER’S SPECIFICATIONS, AND INSTRUCTIONS CAN/WILL CAUSE SERVERE TRANSMISSION DAMAGE AND VOID WARRANTY!
The Throttle Valve Cable (TV) is attached to the throttle linkage. When the throttle is depressed, the cable is "pulled" progressively with throttle position. In addition to providing forced down shifts, (kick downs), and progressively later (high speed) upshifts at higher throttle settings, the throttle valve also main line pressure in the transmission.
Operating a transmission with cable out of adjustment can not only produce early or late up shifts, but incorrect line pressure as well. What this means in simple terms is that, TV pressure too low will produce main line pressure that is also too low, and will eventually "burn" the transmission clutches.
To adjust on the throttle linkage you have 3 things attached if you have cruise, 2 if not. One of them is of coarse of the gas, the one that is for cruise control has a long slot in it. (If you have cruise control) The other is the TV cable. (This is actually a cable) This is the one you need to adjust.
Adjust the cable so that it will be all the way when the throttle is simultaneously opened all of the way. (With the engine off of course).
Bolted to the manifest is a bracket which the cable runs through. With close inspection you will see it has sort of a "D" shaped button you can depress and slide the sleeve (cable housing) back and forth. The sleeve is what you want to adjust by depressing the button. Press and slide towards firewall as far as it will go and let go. Now open the throttle to the wide open position and release. You should be able to hear the sleeve click (ratchet) as it slides through the cable housing. Make sure that the cable returns (with no binding) when the throttle is released.
THIS PRELIMINARY ADJUSTMENT WILL FREQUENTLY BE "TOO HIGH" and the throttle pressure will have to be reduced to attain proper shift points.
** I prefer to start "too high" and work down versus "too low" and work up.
To raise throttle pressure (and raise shift points, and make "kick down" more responsive) move the cable housing towards the firewall (away from the throttle linkage)
As you simultaneously depress the button on the cable housing, move the cable housing away from the carburetor (or throttle body) to increase throttle pressure. Move the cable housing adjustment a small amount at a time (1 click or 1/16 or so) a small adjustment can often make a world of difference.
700R4/2004R TV Cable Adjustment Instructions
WARNING! IMPORTANT NOTICE!
POST INSTALLATION ADJUSTMENT.
It is imperative that after your new TRANSDEPOT 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 TRANSDEPOT'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 TRANSDEPOT 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 TRANSDEPOT 700R4/2004R is replacing an original 700R4/2004R then skip to
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. TRANSDEPOT recommends our universal TV Cable (TRANSDEPOT DTCB1) that is designed to work correctly in any 700R4/2004R application.
Step 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. 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. TRANSDEPOT carries two brackets: TRANSDEPOT has throttle brackets and set ups that work with Rochester Quadrajets, Carter AFBs or Edelbrock Performer carburetors. TRANSDEPOT also carries 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.
. Use the following procedure to determine if your ADJUSTER MOUNTING POINT is correct.
a. Push in the Adjust Tab and retract the Slider . 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).
c. Also note 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 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. c. Road test the vehicle. Under moderate acceleration your shift points should be close to the following: 1-2……15-20 MPH
2-3……35-40 MPH …..3-4…………50-60+ 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/tighten cable. If you continue to have problems, please contact TRANSDEPOT tech department for assistance at 727-868-9462.
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 . 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………45-50 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.
