Will a 700R4 shift without the TV cable?

There are no TV cable, mechanical speedometer drive, or governor provisions. To run a 700-R4 trans behind a carbureted engine without a computer, at the very least the TV cable must be hooked up to the carburetor and properly adjusted.

What happens if TV cable is too tight?

Be aware that a broken or disconnected TV will cause the pressure relief ball in the valve body to become fully seated. When this occurs, the transmission will have maximum line pressure, the shifts will occur extremely hard and late, and at lower vehicle speeds the transmission may not shift at all.

What does the TV cable do on a 700R4?

The TV cable on the 700-R4 and 200-4R transmissions controls line pressure, shift points, shift feel, part throttle downshifts, and detent (full throttle) downshifts. So if the TV cable is not adjusted properly, it can cause numerous transmission problems.

What speed should 700r4 shift at?

We will say that, when properly adjusted, the First-to-Second shift should occur at 15-20 mph; Second-to-Third shift at 25-30 mph; and Third-to-Fourth shift at 40-45 mph.

What makes a 700r4 shift?

The 700R4 uses a cable that connects the throttle linkage to the transmission’s throttle valve (TV) in the valvebody. This is the governor that commands WOT up-shift speeds. The cable moves the throttle valve in the valvebody and increases transmission line pressure as the throttle opens.

What speed should 700R4 shift at?

Does a 700R4 have a kickdown?

The TV cable on the 700R4 and 200-4R transmissions controls line pressure, shift points, shift feel, part throttle downshifts, and detent (full throttle) downshifts. So if the TV cable is not adjusted properly, it can cause numerous transmission problems.

What makes a 700R4 shift?

How much HP can a 700R4 handle?

The Street/Strip 700R4 is good for about 550 hp maximum, but with the HD input drum it is good for about 625 hp max.

Is the 700R4 a good transmission?

The Bottom Line The 700R4 is one of the best automatic transmissions that was launched by General Motors. It was renamed to the 4L60, and the latter also became a popular transmission name. Today, more enhanced transmissions have been launched, and they can still find their roots to the 700R4.

How much horsepower can a 700R4 handle?

What happens when the cable is not adjusted on a 700R4?

The TV cable on the 700R4 and 200-4R transmissions controls line pressure, shift points, shift feel, part throttle downshifts, and detent (full throttle) downshifts. So if the TV cable is not adjusted properly, it can cause numerous transmission problems.

Can a Universal TV cable work on a 700R4?

Monster Transmission & Performance recommends our universal TV Cable that is designed to work correctly in any 700R4/2004R application. 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.

What should the pressure be on a 700R4 TV?

The problem was the TV CL to CL was too long at about 1.45 inches. This means at idle, the TV plunger was too far out and on initial throttle tip-in there was no line rise. On a stock 700 or 200 trans line pressure in Drive at idle should be 65-80 lbs.

Do you need corrector brkt for 700R4 cable?

It is great for a quick install, less fab work, and for the money because it includes the carb linkage, bracket, and cable, its not a bad deal. More often than not you don’t need it, you oftentimes don’t need the corrector brkt either. 1.093-1.125 from CL to CL on the carb, approx 20* to the rear. TV cable bottomed out at WOT.

Will a 700r4 shift without the TV cable?

If youre not going to drive it then youre not going to hurt anything but if you drive it without the tv cable hooked up/adjusted the trans will be junk fairly quickly. TV cable controls line rise/pressure and youll have minimal line pressure without it hooked up which=slipping clutches/band.

How tight should the kickdown cable be?

you want the cable to just about tight at full throttle. so yes, there might be slack in it at part throttle.

What does the TV cable do on a 700r4?

The TV cable on the 700-R4 and 200-4R transmissions controls line pressure, shift points, shift feel, part throttle downshifts, and detent (full throttle) downshifts. So if the TV cable is not adjusted properly, it can cause numerous transmission problems.

Does a 700r4 have shift solenoids?

i would look at the throttle cable first. it needs to be adjusted for proper shifting. the soloniods are in the valve body inside the pan.

Is a TV cable the same as a kickdown cable?

“Kickdown” and “TV” cables aren’t really the same thing. Let’s take it from the top: Many old-school automatic transmissions use both a governor and a vacuum modulator to help regulate automatic shift timing. The governor works off of vehicle speed and engine rpm.

Why does my 700R4 shift so hard?

Some times it is a stuck Throttle valve. If yours has not been taken apart and has not had a spring put inhind the valve they will stick witch will cause late hard shifts. Try taking the cable off of the throttle linkage and pulling it all the way out and then letting go of it so it snaps back into place.

What happens when the cable is not adjusted on a 700R4?

The TV cable on the 700R4 and 200-4R transmissions controls line pressure, shift points, shift feel, part throttle downshifts, and detent (full throttle) downshifts. So if the TV cable is not adjusted properly, it can cause numerous transmission problems.

What causes a 700R4 TV to shift erratically?

THE DAMAGE WILL OCCUR WITHIN A FEW FEET OF DRIVING THE VEHICLE!…… A 700-4R’s shifting can be erratic as a result of improper TV cable lever geometry. In many cases, the shifts are poorly timed and may be early and soft, late and harsh, or a combination of both. Click to expand…

At what speed should a 700R4 shift into overdrive?

We will say that, when properly adjusted, the First-to-Second shift should occur at 15-20 mph; Second-to-Third shift at 25-30 mph; and Third-to-Fourth shift at 40-45 mph. Readjust the cable if the transmission shifts into First, Second, and Third within seconds.

Is a 4L60 the same as a 700R4?

In 1990, GM decided to code and renamed their transmissions, the 700R4 is best described as a 4 speed, longitude transmission rated for vehicles around 6000 lbs. It was this information that was used to change its name to 4L60; therefore, a 700R4 and 4L60 are the same transmission.

Does a 700R4 have a shift solenoid?

Okay, just so you know the TH-700R4 was last made in 1992.. And 700’s do not have shift solenoids. After 1992 the transmission morphed into a 4L60E. This means the transmission will always have the correct oil pressure and shift feel regardless of engine torque.

Why is my t-700r4 transmission not shifting?

Answer: The transmission we are talking about is a General Motors T-700R4. This is a hydraulic transmission, pre-computerized. A very common problem that happens all the time. Even I am not immune to this problem. That being said, it has to be a valve body problem or a governor problem.

How to install a TH-700R4 4L60 transmission?

Raise transmission and install crossmember as- sembly then tighten all bolts. Install three (M10 x 1.5 x 15) flexplate to converter bolts. Install the first bolt finger tight then use the starter motor to “bump” each drive lug into position. When all three bolts are installed torque them to 47Nm (35 ft.lbs.). STEP 8:(FIG.

Is the th-700 transmission a vacuum modulator?

The TH-700 (4L60) transmission does not use a vacuum modulator like some GM transmissions. Instead it uses a Throttle Valve (TV) linkage mechanism to control line pres- sure. It is essential that the TV cable be attached to the carburetor or throttle body and properly adjusted.

Is the GM th700r-4 an overdrive transmission?

This makes the TH700R-4 a prime candidate for a swap into any GM rear-wheel driver as a replacement for a TH350, Powerglide, TH400, or TH200-4R. The TH700R-4 was the first overdrive automatic transmission used in GM cars and trucks in 1982, designated as a Hydra-Matic MD-8 transmission according to GM’s RPO codes.
