What does a constant pressure valve body do?
What does a constant pressure valve body do?
Hear this out loudPauseA TCI exclusive, the Constant Pressure Valve Body ensures that internal line pressure stays at an acceptable level regardless of the TV cable setting.
Why do automatic transmissions have a valve body?
Hear this out loudPauseUnderstanding The Valve Body. The valve body is one of the pieces of equipment that allows an automatic transmission to function correctly. By channeling hydraulic fluid through a series of paths, the valve body is able to trigger the correct clutch pack for the selected gearing.
What is the purpose of a automatic transmission?
Hear this out loudPausePurpose of an Automatic Transmission Just like that of a manual transmission, the automatic transmission’s primary job is to allow the engine to operate in its narrow range of speeds while providing a wide range of output speeds.
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.
Why was a forward clutch checkball added to a 700R4?
Apparently when the Auxiliary Valve Body was added (1987-1993), checkball #5 (pictured above) was removed, and checkball #12 (Forward Clutch checkball) was added to the Auxiliary Valve Body. This was done to force Forward Clutch feed oil through an orifice. It doesn’t take much to get the flow of fluid out of whack in these transmissions.
How do you line up the separator plate on a 700R4?
Lining up Valve Body Gaskets and Separator Plate – If the dowel pins are not present or have receded into case, use a hand full of the Valve Body bolts to line up the gaskets and plate. Thread a few bolts into the case starting near the Shifter Detent and working diagonally towards the 1-2 Accumulator.

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.
When was the transmission changed to the 4L60?
It is also very easy to find replacement parts for this transmission. The 700r4 transmission was not electronically controlled yet; it was hydraulic pressure controlled with a TV cable which acted as a throttle position sensor to control the gear shifting. In 1991~ the 700r4 transmission was replaced by the popular transmission 4L60.
