I have a 2010 F-250 XLT 4WD that suddenly started to not accelerate when i was about 2 minutes from my home. Ran a test on it and it is throwing the following codes:
P2703 Transmission Friction Element D Apply time
P2701 Transmission Friction Element B Apply time
P0766 Shift Solenoid 4 electrical
P0756 Shift Solenoid 2 performance
P0721 Output Speed Sensor Noise Interference

Some forums i have read stated to replace the transmission all together, Some have said to just drop the pan, check the fluid for a metallic look and metal shavings, and the final few have stated to perform a fluid flush first and a filter chance. Im lost as to what to do. I do not want to take the truck into the dealership as this dealership has always screwed me. I wanted to if anyone has had this happen on their truck and what they did in the long run.

 

Hi T,
This may or may not be the answer, however, it is worth a shot and the only cost is some of your time.

From the info you provided It seems the codes are attempting to tell us something.
When we get a bunch of codes as is the case here, a good part of the time there is a ground connection problem which is shared by the components listed.
Before going off the deep end , If you can, check all the ground connections you can find especially those where there are plugs going to the trans.
Look for corrosion inside the plugs. .
Sometimes here is how this goes, they pull the trans do whatever they do and plug everything back in and everything is fine (for a while).
OR,,,,,,,,,,the trans gets replaced and the problem is still there and that leaves a miserable feeling.
Soooo,,,,check the connections, only your time and hopefully no $$$ and see what you find.If you find a possible problem cause we all would appreciate if you would share the cause and solution, OK , thanks.
