Re: Code P094 Shift A Solenoid Speed Sensor Where and what is it 94 Concours?
a) the job is a mess, be prepared.
b) drop the transmission pan, and careful removing the tranny gasket, it is re-usable. Once you clean the pan, you can reset it with gasket sealer.
c) Okay, before you drop the valve body, you must disconnect the solenoid harnesses and there is a steel rod that actuates a valve spool that must be disconnected. It has a spring steel retainer clip that must be lifted and slid back for the rod to be disconnect. BE CAREFUL, spool can slide out, you do NOT want to damage this piece.
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 contually leak. Best thing is to set it on cardboard on a bench.
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 valave body split, this is where the solenoids are located. 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 fly, as well)
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 platsic 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 (discrad 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
I just replaced my solenoids and it is DIY repair if you are mechanically inclined and like working on cars.
