Yes. But I replaced mine as an "upgrade" in the 98 Mustang tranny I had installed after full JMOD as well as other internal upgrades.

I installed a;

-Pressure Control Solenoid (EPC): XL3Z-7G383-AA
but that was for a 98+ tranny. Not sure if it'll work in a OBD-I(pre-98 4R70W)

I got the code on my tranny when it started acting up so I'm going to change it this weekend along with the fluid. Just wondering if there is anything else I should do and how common this is. I read that page and saw not to adjust the screw on the back. By the way my tranny is in a 98 lsc

haha, I do rodeo here so I had to think about that one (flagracing is a rodeo event)

Remove the pan (maybe put in a drain at this time for future ease)

You Need to remove the pin on the right to get the rooster out, remove the MLPS. It's not in this photo, but loosen the bolt that holds the pressure roller on the rooster as well., SAVE THE PIN! Push the rooster and shift connector out of the side of the transmission.

Push the piston into the valve body to move it out of the way.

Depending on the year, you probably have a wire harness instead of the black circuit board. Whatever you have, carefully remove the electrical connection to the EPC.

Remove the bolt above it to the left, that holds the bracket that holds the EPC in.

Carefully pull it out, you will have to wiggle it and the seal may be a little stuck at first.


Clean the pan, get some fresh Mercon V, a new filter kit, reassemble in reverse order. Tap the pin in with a hammer, don't smash it all the way, just till it's the same depth. The Rooster pin has a notch at the correct depth for sliding it in. Don't be like many of us and forget to align the rooster with the piston for the valve body!! (The big oval) When you are done it needs to look exactly like when you began.

GREAT JOB Flagracer~! - The only thing I'll add is BE CAREFUL - Remember that Rooster Linkage is connected to PARK PAWL so make damn sure Tires are chocked, E Brake On, etc... These Threads always remind me of a guy I worked with who DIED doing his U-Joints, not the way I want to go out...

Well it was a success yesterday with replacing the EPC. A friend of mine is a mechanic for Mercedes and he's been a ford guy all this life so we tackled the job. When I met up with him Saturday he already removed the EPC Friday after work(the car was at the shop on his lift). So he puts it in and replaces the EPC and it's wango bango we're in the money the job is done. Wrong Wrong Wrong we run into an electrical problem while driving. The overdrive light is blinking and it's not shifting right. So we go back and ohm the wires from the from the PCM i think he called it to the tranny and we're good. Now we look at the tranny for the electrical problem and it's the we pull the long circut board and it's not looking ohm right so we call the ford parts store and they have it so we're in the money and get a great deal for 40 bucks for it. Now we think that's it. As we take a closier look at the new board and the old one we then see something is burned into so he goes and breaks and pushed the solenoid up and it breaks which is fine at this point we didnt know it at the time and see that that # 4 pin or connecter is burned and gone. That one is the power to the tranny. We're like oh sheet and we call up ford again and see if they have it and they do but can not find it. We wait 30 minutes for the guy to find it and get it for 20 bucks and we're in the money now. We realized that the valve body had to be lowered to intall this solenoid. We do that connect everything back up. Fill up with some Mercon V and and some Mobile 1 we're getting 20 miles to the gallon in the city. We also changed the plugs he talked me into E3 and they're alright. But it was a success story. Thank you guys

lower left corner is the shift solenoid barely peeking in.

they are two side-by-side square boxes.

replace both.


in the photo below are:

the wire harness leading across and UP is the EPC solenoid
the black round cylinder on the right side is the TCC solenoid
just behind the TCC solenoid you see a silver square-that's the SS(shift solenoid) 1 of 2




replace them both.
those in the know will also spot a critical error in this photo...care to call it out?


EDIT:
better photo
see the two square silver boxes?

SS1 and SS2
