Please Help!! Transmission Code: Pressure Regulator EDS 5

[civdiv99]

Well, if ya hear hoof beats, think horses before aliens.

If you have a diag code for EDS 5, it doesn't necessarily mean order a pressure solenoid, but it doesn't really mean start with something else either. Test the obvious first.

Find conn X70004 on the TCM under the plastic cover in engine bay, passenger side, at the firewall. Read (on the plug, not the TCM socket) between pins 3 & 12 (EDS 2), 7 & 12 (EDS 3), 11 & 12 (EDS 4), and 15 & 12 (EDS 5).

Then do a "which one of these is not like the other" analysis, since they should each come in at about 7 ohms, give or take .8. Civdiv's take is that if you have a problem, it'll be obvious. Meaning you probably won't see something like 5 ohms or 10 ohms leaving you in a dilemma. If you do, think it through - flakey contact won't give you a lower reading - shorted solenoid coils or chaffed wiring contacting bad things could. Higher reading but not "open" indicates connection/contact issue is likely, since an actually open coil winding would not be higher resistance, it'd read as if open and infinite resistance (as far as we are concerned here).

If you are going to pursue a possible connection issue, start under the car at the trans connector, as it lives in the weather. You will find that the connector is well sealed with its little oring and stuff. It also requires room under there to contort to work with, so please have the car well supported as if your life depends on it. (hint).

That's really all I can do for you. Your code is pointing in a direction, and whether the solenoid itself is bad or not, as long as the car thinks it is, that'll need to be addressed. Your choice now is really down to what is your time and ability worth -DIY v. pay by the hour someone else.
