2010 Explorer 4.0 with a 5r55s Transmission

[Robs 2010 Fords]

Hi folks,
My 16 year-old son and I bought this vehicle 10 months ago. 150k miles. Recently, the wrench and CEL lit up and the transmission went into limp mode No overdrive-off response. It clunks a little when shifting into R and D. Smooth from D to 3. There is a leak from the front of the transmission, and the shift lever cycle seems loose.

Codes were:
P0316- Misfire detected
P0713- Transmission fluid temp
P0731-Gear ratio incorrect
P0732-Gear ratio incorrect in 2nd
P0733-Gear ratio incorrect in 3rd
P040 -Torque converter fault
P0743-TCC System fault


We dropped the pan, and the fluid level was low and varnished. There was some metal on the magnet, but not much. We changed the filter, added fluid.

Codes now are:

P0743 - Torque Converter Clutch Circuit Electrical
P0750 Shift Solenoid A Malfunction
P0755 Shift Solenoid B Malfunction
P0760 Shift Solenoid C Malfunction

P0962 - Pressure Control Solenoid A Control Circuit Low
P0966 - Pressure Control Solenoid B Control Circuit range/performance
P0966 - Pressure Control Solenoid B Control Circuit Low
P0970 - Pressure Control Solenoid C Control Circuit Low

Are any other things an intermediate mechanic should try or is it time to punt? I can replace

Remove the electrical case connector from the transmission and check for corrosion, its a common spot for electrical issues. If corrosion is found you will have to replace the solenoid block and rewire in a new harness pigtail connector.

The gear ratio codes and the converter code are not good codes to have and may indicate a internal issue.

Thanks, I'll check the connector and wiring harness! I'm hoping the overheat didnt do any internal damage, but only caused damage to the wiring. I have two of the exact make, model, year and color. I pulled the transmission solinoid fuse (#38 in the under-hoof fuse block) on the "good" Explorer and got the exact same codes. Hopefully there is just a little corrosion in the plug. I will post an update.

Quick question, I inspected the wiring and everything looks good. I am planning on pulling the transmission case connector ("TCC") and checking the voltage (TCC pin #3). Since all shift (except D), pressure control, and TCC solenoids are in open revolt, I'm going to test the the primary ground to the PCM (#17) just for kicks and giggles. Is these anything else I should check? My TCC has the official Ford duct tape correction:

James nailed it. One rewired plug and solenoid pack later and its up and running. Thanks!
