4l60 Transmission Wiring Diagram. There will be primary lines which are represented by l1 l2 l3 and so on. As the gif above shows the bottom line is the hot line which sends warm transmission fluid out to the factory trans cooler within the radiator at the lower port in most cases.
Instead it uses a throttle valve tv linkage mechanism to control line pres sure. Each part should be placed and linked to other parts in specific way. If the cable is not connected correctly the transmission will not shift correctly and it may fail.
Fyi some vehicles have the factory cooler on the bottom of the radiator but simply follow the lower cooler line coming from the transmission to find the.
It is essential that the tv cable be attached to the carburetor or throttle body and properly adjusted. The vss signal is the output of a variable reluctance sensor. It shows the components of the circuit as simplified shapes and the capability and signal links in the midst of the devices. Fyi some vehicles have the factory cooler on the bottom of the radiator but simply follow the lower cooler line coming from the transmission to find the.
