SELECTOR VALVE INSTALLATION
The selector valve is installed into the existing transmission/cooler lubrication line, which carries the fluid from the transmission to the radiator (cooler). A second line (hose) normally runs alongside this line to carry the fluid from the radiator back to the transmission.
Refer to DIAGRAM
1, page 7.
NOTE: Some orderly planning should be given to the location of the selector valve. Consider the following:
The selector valve can be mounted near the hose line between the transmission and the radiator. If the existing lines will permit, it is better to locate the valve higher in the engine compartment along the inner fender wall.
The valve and hoses should be located where they will not be damaged by road hazards, other moving parts, sharp edges, or hot exhaust parts. The valve can be secured by using plastic ties included in the kit.
3. Hoses should not be bent too sharply causing a restriction in the fluid flow.
THE SELECTOR VALVE MUST BE CONNECTED INTO
THE HOSE, WHICH CARRIES THE TRANSMISSION FLUID FROM THE TRANSMISSION TO THE RADIATOR WHEN THE VEHICLE’S ENGINE IS RUNNING.
TO DETERMINE WHICH HOSE MUST BE USED, FOLLOW THESE STEPS:
Disconnect one of the rubber radiator hoses from the steel transmission line at the transmission. Expect a small amount of fluid to drain from the line. (Hint: On most front wheel drive GM vehicles the line is steel at the cooler and transmission with a 6” section of rubber-type hose in the middle. On these transmissions, look at the bottom of the transmission. There are two steel lines coming out. The one that comes straight down toward the ground is the one used. Cut the section of rubber-type hose in this line. Be sure you double check. On rear wheel drive GM’s you will be using the special GM T-fittings. The correct line is usually the bottom steel line on the passenger side of the radiator/cooler. Again, be sure you double check that you have the correct line.)
