The TFT sensor is located right on the filter IIRC.
I've heard from trans techs that 4F27E has valve body wear problems that are pretty common. Meaning simply changing solenoids ain't gonna do it all the time.
I have not run into it on these but my previous Contour would disable OD when a spark plug wire got bad enough and the engine performance really did not reflect it either, no missing that I could perceive. I simply changed plugs and suddenly no OD. Found out and change wires and then OD is back. I guess I damaged a wire pulling them. Wonky...........

|RuffnRider77||I have seen a fair amount of internal harnesses in the trans causing it to do this style concern as well as possible taking the solinoid out, the tft is loacated int the trans in the valve body, usually when it gets hotter it will change the resistance of the wires and cause these faults. I could be incorrect just saying from my experince its a slightly less expensive try than a whole tranny.|

|Johninmass||Where is the Transmission Fluid Temp (TFT) sensor located?|

It could be the Transmission Fluid Temp (TFT) sensor.
(or the wiring to it)
The CPU won't let the car get into 4th gear if it's too cold
It won't lock up the converter if it's too hot.
If it gets too hot, it will enter a pre-set shift mode, disable the lockup in 2,3,4 gears, and turn on the dash light

Still need ideas if anyone can help.
I'm about to replace the whole tranny with a used one. $200 with 90K on it.

Good article referenced.
The "!" can indicate ATX fluid overheated, SPI engine (means something else on ZETEC), or a speed sensor failing - which combined with your ATX starting off in 2nd may be a strong case for the OSS.

The ! could be an indication of a transmission malfunction - not an overheat (from what I understand).
Have you looked into the solenoids yet?

|Johninmass||Still working on problem. Anyone have any other ideas.|

|BlueOvalWRC||You could give these guys a call and see if a complete valve body might be the solution. Lentech|

|Johninmass||Thanks for the link. Does anyone think it's the EPC solenoid?|
