Can you run a 700R4 without a TV cable?

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. Not just a simple kickdown cable like your TH350 analogue, the TV cable controls line pressure and shift points.

Does 700r4 have TV cable?

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 is the plug on the side of a 700r4?

the plug on the left side only controls the converter clutch. you really need to use the lock up feature,if not you will eventually burn up the trans. if you do a lot of interstate driving.as the converter will not get any cooling lube with the lockup feature not working.

What does a transmission TV cable do?

As the throttle opens, the cable is pulled out of the transmission, signaling the transmission to increase line pressure to accommodate the additional torque. TV cable position also determines shift quality and firmness and controls all shift timing events.

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.

HOW TO: ADJUSTING A 700R4 TV CABLE

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.

How does 700r4 lock up work?

The GM 700-R4 & 200-4R transmissions utilize a lock up converter to help create a more efficient transmission. It takes stress off the fluid coupling of the torque converter and it helps decrease the amount of heat being generated at higher cruising speeds.

How do I know if my 700r4 is locked up?

12 volts is applied to a solenoid valve in the transmission when in 4th gear determined by a 4th gear pressure switch in the transmission. You can tell if it is in lock up by watching the tach when you accelerate or decelerate in 4th gear. If it's not in lock up, the tack will move up or down rapidly.

What year 700R4 is best?

Generally, 1987 and up TH700R4s or 1990-'93 4L60 units are the most desirable.

What does a transmission lock up kit do?

Torque converter lockup kits can save your engine, and your wallet, in the long run, if you use your vehicle for towing, touring, or rigorous off-road driving. A torque converter lockup kit keeps the transmission fluid cool and alleviates the strain placed on the coupling itself.

How do you bypass a TCC solenoid?

To bypass the shift and TCC solenoids, you simply need to connect standard 194 light bulbs to these individual circuits coming from the PCM and then connect the other side of the bulbs to ignition B+. The light bulbs will then serve as a "load" which will simulate the solenoids.

How do I know if my kick down cable is bad?

How much torque can a stock 700R4 handle?

I've read a stock 700r4 can handle 350 lb-ft of torque. But some were rated higher depending on it's application. 1989 was not a high horsepower maybe 230 or torque motor if I recall correctly. You could just have that trans freshened up to handle new motor.

Do all 700R4 have overdrive?

In conclusion, the 700r4 transmission is a 4-geared hydraulic automatic transmission with the 4th gear, an overdrive gear (30% increase).

What is a Level 3 transmission?

The Level 3-4R100/E40D Transmission comes with deep pan, highly modified valve body and modified pump. Clutch packs are highly modified for increased durability. Torque converter is triple disc with billet cover and steel stator.

What is a Level 2 transmission?

Level 1 : Shift level one has a stock factory shift with small modifications to improve durability of the transmission. Level 2 : Shift level two is a firmer shift for mild performance and towing applications. Level 3 : Shift level three is for high performance vehicles using a high stall converter.

What does a kickdown solenoid do?

A kick down solenoid is provided in the first shift down circuit for controlling the first shift down circuit and a kick down switch is adapted to be actuated by an engine control member.

Does throttle cable affect transmission?

The throttle valve cable is used to control the line pressure, downshifting and the feel of the shifting. When the throttle valve cable is out of specification, the transmission can shift early, shift late or not shift at all.
