Hey guys, just a quick question here. I need to replace my TFT sensor as I've got the "check guage" light on as well as the Tow/Haul light on (flashing) Everything I've read here is pointing me in the direction of the TFT sensor.

With that said, I called my local dealer, and they quoted me $91.00 I was like So, my question is this: Does that sound right to you guys, and if not, where can I order one, because so far, all the auto parts stores around me don't have it, so I'm thinking it's either going to be through the local dealer, or online somewhere. Also, what about the Mercon SP fluid? Where are you guys getting your stuff at?

Thanks in advance for any help.

 

Mercon SP = dealer. TFT sensor= partsguyed.com

 

I think the only place your going to get it is at a Ford dealer. The last price on one 9 months ago was about $78 I got one for a jobber price of $47. You can put several thousand dollars worth of these TFT sensors in your shirt pocket, thats how small they are.

 

When you replace it make sure you turn the old one 90 degrees and pull it down with a needle nose pliers. The end of the TFT sensor is T shaped with an O ring on the end of it, this is what locks it in. Make sure your face is clear when removing the old one because you will get a gush of fluid that will drain out.

 

Thanks guys!

 

Sorry for my ignorance but what is a TFT sensor?

 

Here is an R&R guide:

Transmission Fluid Temperature Sensor.

Anybody happen to know the part number? I'm having a heck of a time finding in at www.partsguyed.com

 

I couldn't find it either. His lists leave a lot to be desired, but his reponse to email is excellent. He'll find it for you.

 

Thanks again. I just sent him an email, so I'll wait and see what he can find.

BTW, thanks for the links in your earlier post. Those will help as I've never done this before. Much appreciated.

 

No problem. In return, when you get the part number, come back and post it for others to find in the future. And if you are really energetic, take a few photos of the job and post them here.

 

Will do.

 

I had the flashing Tow Haul light on the return from a recent camping trip pulling a large fifth wheel. I read a number of threads here and had the exact symptoms described. I changed the TFT sensor and it solved the problem. I chose to respond to this thread because it has the best link to technical information about replacing the sensor. See post #7 above.

 

Just as a standard operating procedure.

I would always clear all the computers (complete power down and drain) and see if that clears up the problem before I touch a wrench.

Then, the first suspect is always bad contacts / wiring / etc.

Only if those things check, do I start throwing parts $$$ at it.

 

79.00 in Killeen Texas for the sensor
