5R55E EPC Relief Valve Question

[strocket]

I tore down my valve body a few days ago and saw that I was missing my EPC screen and also my EPC valve and spring. The last time that my transmission was rebuilt was a few years ago by ford. When I noticed that it was missing and went and ordered another one. Well today I went to pick up the parts and when I did I had two problems. The first one was that the valve wasnt metal, and the second was it didnt come with the springs and the springs werent orderable because they were part of the valve body assembly. So I would have had to order a brand new valve body just to get that spring. So since it didnt have one before and ford was the last guys touch it, should I just put it back on without it like it was before or keep searching for someone that sells that spring??

I recommend you review the 5R55E valve body diary and in there you will see a modification kit that ford put out. They have eliminated the black button/spring/screen for the EPC limit circuit. Was there a reason you took the VB off?

Which diagram were you originally looking at to see which parts were missing?

This thread should have all of the necessary diagrams.

The EPC limit valve,spring and screen were eliminated with the installation of the service replacement separator plate and new EPC blow off valve.

It's normal.

What year does this upgrade start with? Could it be applied to all models from 95-up with an EPC solenoid? Is it a TSB?

Out of specification pressures controlled by the transmission main control valve body separator plate may be the cause.

Thank you guys for yalls help!! I got the trans back together and now im having problems putting the tranny back into the truck. Im able to get everything lined up and ready to seat but I cant push it forward. Its almost as if something is stopping it from seating. I made sure that the TC was locked in. I dont know why this thing wont just slide on as easy as it slid off. Any one have any tips on how to get this ***** back on??

Make sure that the exhaust is not in the way. The torque converter must be properly seated first into the bellhousing before installing it.
