On way RV show today, tow/haul starts flashing. On way home, still flashing, also have check engine light now too with a P0713 code. I noticed also the guage on dash for tranny temp isnt moved. I checked SGII and it said TFT was 8135 degress? It def wasnt shifting too well but i got it home and its in garage and i need some help on what this may be.

 

I think you definately have a bad temp sensor. If it was that high you would have a puddle of melted aluminum under your truck and no transmission.

 

I had the same thing happen to me. all you need to a new sensor and oil. pan gasket and the screen filter are reusable. no need to waste money on those parts. you should also replace the inline filter by the radiator.

Click here for Change Pics^^^^^^^^^^^^^^^^^^^^^
When the PCM sees TFT That High it goes Into Limp Mode

Normaly change temp sender inspect harness and problem solved


Watch the TFT As truck Comes to Normal Temp If it Jumps its Tempeture around And Normaly pretty Drastic Jumps Way High to Low F* then about a 99.5% chance Sensor is BAD

 

where do i get that filter? is it something i can do myself? my guage on dash wont move at all.

 

is ford the only place to get that tranny fluid mercon sp? no auto parts stores seemed to have it.
so is this a good time to change the fluid? how much more do i need to get and is a flush necessary to change fluid?

 

DFO Diesel Filters Online Has Good Deals on Filters and they Have Mercon SP

They May even Have a New TFT Sensor IDK

I reaserched it some I need to change my TFT sender before Summer comes

Just do a Spill N Fill on Fluid and Change that Filter and sender you will be good to Go

I wouldnt worrey about Flush

Should be able to reuse the Trans Pan Gasket too

 

I use Valvoline atf with the lv/sp additive. just the back label. the hardest part is getting the inline filter apart. An impact gun works best.
