Directions

>a) drop the pan, and careful removing the tranny gasket, it is steel and
>re-usable. Once you clean the pan, you can reset it with gasket sealer.
>c) disconnect the solenoid electrical connectors and the mechanical
>linkage. The linkage has a metal clip you lift and slide.
>d) remove the valve body screws, and drop the valve body.
>e) place the valve body where you can afford a mess, it will continually
>leak. Best thing is to set it on cardboard on a bench. There is a valve
>spool that can be removed as well, careful it can slip out, you don't want
>to damage it.
>f) remove the two clips holding the solenoids, careful they are
>spring-loaded and will fly
>g) remove the screws holding the "large" portion of the valve body split,
>this is where the solenoids are incased. Remember the screw locations,
>there are about four different screw lengths
>h) CAREFULLY remove split, there are 4 steel check balls loose inside the
>split (about 1/4" diameter, they will roll away)
>i) inspect spacer plate, if the black coating is not chipping off you can
>re-use it, otherwise plan on spending another $ 70 at the dealership parts
>house. If you replace it you will have to remove the "smaller" split, as
>well. It also has three check balls.
>j) replace the solenoids
>k) now comes the fun,....you will note three holes in the spacer plate
>where three of the check balls reside, seat them there (appr. 3/16"
>diameter with a smaller relief hole next to it, as I remember). The fourth
>check ball will need to be inserted in a spherically-cast cavity which is
>near one the solenoids. You can set it with grease, I re-assembled
>successfully without using grease.
>l) re-assemble valve body, carefully and equally torque.
>m) you will note a square black plastic item near one of the solenoids, on
>the end. Replace this plastic filter with the new filter in the solenoid
>kit. The kit will also come with an L-shaped bracket that is to be used to
>"capture" this filter and keep it from backing out. The kit also comes with
>a slightly longer screw used to mount the bracket to the valve body
>(discard the old screw).
>m) re-assemble valve body to transmission, hook up linkage and electrical
>connectors
>n) replace both tranny filters
>o) replenish fluid
>p) reset codes
>q) one more thing . when spliting the valve body its good to draw a diagram of it and set your bolts on the diagram (where they go) because the are dif lengths.
