What would cause a 700R4 not to shift?
Either the T.V. piston is sticking in the valve body (common) or the T.V. cable isn’t operating properly.
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.
What does the governor do on a 700R4?
The transmission governor on a 700R4 is used to regulate the speed at which the transmission shifts into the next higher or lower gear. It accomplishes this through the use of two sets of centrifugal weights, each a different weight.
How many times does a 700R4 shift?
Currently shifts from 1st to 2nd at about 4500 and from 2nd to 3rd at about 4800. The weights and springs on the servo are changed to move the shift points around. The TV cable can also play a small part in shift points.
What is the plug on the side of a 700R4?
There is a four plug connector on the side of the 700r4, but it is unusual that all four of the connection get used. Most of the time one of the wires is a ground, another is a sensor feed back for the computer and then the TCC control signal.
Will a 700R4 work without a computer?
a 700R4 will work fine with or without a Lock-up converter. It is not going to over heat if it is adjusted correctly and the cooling lines are intact and flow freely.
How much horsepower can a 700R4 transmission 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. Add another $240.00 for the input drum.
What’s the difference between a 700R4 and a 4L60?
Well, the 700r4 uses a TV cable as the speedometer, and the 4L60 is an electronically controlled transmission, so if you see wires coming to the transmission on the rear of the transmission on the passenger side, you have a 4L60. The safest way of checking your transmission is to look at the identification tag on the transmission.
How can I tell if I have a 700R4 transmission?
However, there are some ways to determine if you have a 200-4r, 700r4, TH350 or a 4L60 transmission. The easiest way to identify if you have a 700r4 is to raise your car and check the bolts around the transfer case.
Do you have to rebuild a 700R4 torque converter?
The transmission will have to be removed and rebuilt. Always install a new torque converter when the transmission is rebuilt. Never try to save money by reusing a torque converter that is full of debris from a failed transmission. This 700R4 converter also has a clutch in it that could be bad.
What’s the difference between a 700R4 and a TH350?
The 700r4 and the 200-R4 transmission replaced the TH350 transmission at that year. The TH350 was a 3 geared transmission without the last overdrive gear. The 700r4 was a big upgrade with an additional gear (Overdrive), the 1st and 2nd gear became longer, and the transmission case itself became a bit longer.
