Magnet
Did you happen to clean off the magnet about the drain plug? Just wondering how much "fuzz" there was. I just finished the job (THANK YOU SO MUCH btw) and was not sure if my accumulation was excessive for 200k or not. Thanks again

Possibly.... and unfortunately that's the best I can give you. I don't know if your Expedition uses the 4R100 or a different transmission. If it's a 4R100 then it is VERY likely the same part. If not... it still could be. Best way to know is to get the part# from your local Ford dealership.
I found this thread because I've had some tranny issues and now the P0713 is the last code I need to sort out. I really don't want to drop the pan, drain, make mess, blah blah but if this turns out to be my fix, then I'll do it gladly. I won't smile though; tranny fluid tastes terrible.
Any chance you still have the Part#?

Heres my attempt to give back to FTE. Didn't see anything in the tech folder about this. There were some quick posts about it but nothing with shiny pictures.
1. Purchase a new TFT sensor($14.49) and 8-10 Quarts of Mercron LV or SP ($4.49 per quart) at your local Ford Dealership.
2. Drain your old transmisson fluid.
3. Remove your Tranny pan by loosening 20x10MM that are around the edges.
4. Lower the pan and be careful with the gasket it is re-useable.
5. On the passengers side of the valve body in the front you should see the TFT sensor between 2 Solinoids. (See Photo)
6. Disconnect the 2 wire harness and with a pair of needle nose pliers rotate the TFT sensor clockwise with pulling down slightly. FYI Get out of the way or your going to drink some fluid.
7. Install the new sensor by inserting it in the same hole and rotateing counter clockwise. Reconnect 2 wire harness make sure its on the right side where the harness lock is.
8. Clean up the Tranny pan and re-install bolts. Torque bolts to 11Ft lbs.
9. Fill tranny up with Mercron LV or SP. Took me 9 Quarts which is what came out.
10. Check for leaks around the pan and enjoy not having your Trans guage spike.

It was my pleasure to help in whatever way I can.
While I agree the techs that come here to help us all out are awesome. I am not a fan of dealerships either. I would prefer to pay the techs directly if possible. Also the parts department is what gets to me. But I respect the techs here enough to keep my posts free of. Cheezit has been spot on every time.

I have had a few of them work on my truck on the weekend, we all need/want extra $$$

My sensor lock clip
I am pissed guys. Chalk it up to my fat fingers, or bad sequencing but while I was removing the sensor I broke the lock clip. Is there a quick fix or is the enough connector snug enough to prevent the harness falling out? I need some good advice to a bad scenario. Thanks.

TFT Replaced. P0713 GONE
saharts - great repost. 2005 F250SD 4WD Automatic Trans - Bought the $13.99 sensor, both tranny filters $55 (internal and remote element) and 10 quarts of Mercon SP $116. Just over 30 minutes after starting; THE JOB WAS COMPLETE AND CODE CLEARED! No more blinking tow/haul/check gauges. Our 250SD never did experience any shifting issues, limp mode or irregular performance or lack thereof. Shop quoted me just shy of $600 to do it. Under 1/3 of the cost plus my 30 minutes and no more P0713. In the process, I did go one step further when it came to disconnecting the 2-wire plug. I took a picture, blew it up on my phone so I was sure of how it released making sure I didn't break the lock clip.
