2007 sport trac multiple dtcs please help

[rjcamel2355]

I have a 2007 sport Trac 4.0 v6 2wd. I was driving home A few days ago and without warning my truck became doggish no power unless I gave 60% or more throttle. I was doing 65mph. No loud noises or jerking or any other types or signs of breaking. I limped it home it seemed as though there was only one gear it was in.

Took it to the dealer today with a new pcm. They said it isn't the pcm and I should buy a new transmission. I have attached my code scanner code results. The truck goes into park neutral reverse and drive. It will not manually shift into 1,2, or 3 on the console shifter and in drive it seems to be in 3rd gear no power taking off. No broken or burnt wires anywhere I have traced them multiple times.

Possibly a range sensor? Or what do you guys think anything would be helpful I'm at a loss here.


Driving it to the dealer, on my way back my doors auto locked at about 55MPH which I know isn't normal. I'm guessing it is a sensor, or something electrical I checked the fluid, no burnt fluid, full of clean bright red clean smelling fluid. No debris that I noticed, and no broken parts, or anything leaking around the pan or case.


Any ideas, I'll take a shot at anything. I can have it rebuilt for 800-900, but I'd rather not spend it if it's something simple like a sensor.

The first code that I noticed was the Torque Converter Clutch Circuit. When I put it in reverse from park, or drive it's got kind of a "clunk" to it, like a hard shift down into that gear, but I imagine if it's having electrical or computer problems it's not going to act very normal.

I've been told the Range sensors can go bad and haywire causing the wipers to come on and all kinds of things, but I am not transmission expert. My speedometer also stopped working for a little bit, but then started working fine again. Possible that all of these things are related?

Prior to all of this, I replaced the heater core, vehicle worked fine after that no issues, not DTCs, I sprayed some sea foam down the throttle body a month or so after doing the heater core. I noticed some wires that were bare (coating off of them) around the MAF sensor, and leading to a sensor on the throttle body. I taped those up making sure nothing was bare or touching. and took the truck on a 200 mile trip , and then I started having these issues. I know the wires aren't touching thats the first thing I checked, no blown or broken fuses.

Possible transmission case ground issue?
Transmission Range Sensor?

Those are about the last two things I could possibly think it could be that I could DIY fix

Since that includes codes for o2 as well as Trans issues, that would leave me to believe that you have issues with the trans harness (since its all one piece and includes o2 sensors).

I've been wondering that myself. I read something about water getting on the solenoid connector on the transmission and causing problems but with 7 inches of snow on the ground I haven't got the chance to check yet. I guess I need to pull the harness and go over it really good. I dony believe Ford at all telling me to just buy a new tranny

Shift solenoid pack, AND connector. Connector was toast on the inside, corrosion and burnt. Some of the pins that it connected to on the shift pack came out with the connector so I imagine the computer was going a little crazy. Never popped a single fuse or relay though, which is kind of odd to me, However It's still cheaper than a tranny rebuild. Anyone know where I can get a new connector cheap? they're 100$+ online, and 150 for a reman shift pack, 250 for a new.
