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. Slugs will not install flush with the plate, there will be a small margin of the slug visible as shown below. Insert slugs with a hammer (lightly), with the round side of the plug facing up, from the Valve Body side of the plate. If the existing plate looks like the one pictured above, slugs are needed in both locations on your new plate (assuming the new plate has holes). Check the existing Separator Plate for holes in the following locations. Separator Plate Slugs – Used in two locations given the Valve Body does not have a roll pin and/or transmission has an Auxiliary Valve Body. A bench grinder was used on this particular plate. In the photo below, you will see the four grooves tucked behind the snap ring. This is done to allow for a less restrictive flow of oil from the second and fourth pistons. Steel Plate in servo modification – Cutting grooves in the Steel Plate in the Servo is a common modification. I suggest avoid using the Anti-stick Spring with the grooved Throttle Valve. If the spring hangs on the grooved valve, it causes throttle pressure to remain high. This spring works well to upgrade an OEM or a smooth tailed Throttle Valve however, it tends to actually get hung on replacement valves with grooves on the tail (pictured above).

This spring is used to keep the Throttle Valve from sticking, which helps to maintain control of throttle pressure.

Let’s start with the Anti-stick Spring.Īnti-stick Spring – This is the small (.015” diameter) tapered spring which goes between the Throttle Valve and the Valve Body casting (or TV Bushing if equipped). There is not likely any new information here however, I have tried to compile a short list of tried and true techniques that I have personally had success with. If you’re diving into your first 700R4 rebuild (or maybe it’s just been a while), and are looking to verify some of the suggestions from your friends, local mechanics, or even the instructions from your rebuild kit, this is the write-up for you.
