so does that mean your problem has gone away with the tranny tune from the edge?

if so, do you have the leave the programmer hooked up to keep the problem from reoccuring?

what happens if you program it and remove the programmer?

With the Trans tune, the problem goes away but any other setting it comes back. I wish I was home enough to troubleshoot the problem...being overseas has limited my time.

I have not tried setting the program and then removing it...I'll try that when i'm home in May

I've also come across something else. Apparently there is a TSB for the 2005 F150s for our issue.

TSB 09-20-14: "Some 2005-2010 vehicles equipped with a 4R70/70E-W transmission may experience an un-commanded torque converter clutch (TCC) apply or TCC partial apply immediately after the 1-2 shift. This may result in the perception that the vehicle lacks power or that the transmission is up-shifting too early. Additioanl symptoms of uncommanded TCC apply when coming to a stop (before the 2-1 downshift is commanded), are engine stalling or lugging when engaging manual 2nd while at a stop and code P1742 may be present in continuous memory. However, the vehicle should operate normally in park, reverse, neutral, and manual 1st gear."

I had this exact same issue and chose to try replacing basically every component in the fuel system . Fuel injectors,filter, and pump replaced. Speed and ABS sensors replaced . No change . I decided to try turning the overdrive off . IT WORKED! But now after about 2k miles (163k) the issue is starting to happen while OD is off . Can someone explain why/what is going on ?? Nobody on the forums have seemed to figure it out yet !

You have likely have undiagnosed misfires. Turning off the overdrive helped at first because the engine running at higher rpm compensated, but now the misfire is getting worse to where it can't be ignored...

I was experiencing my 2004 Ford F150 bogging down after the engine warmed up. I had tried coil packs, plugs, Fuel Pump module, etc etc. Of all places I was reading through Amazon reviews and I noticed a person commenting on recalibrating throttle body. I followed the steps and BAM! Truck is running like a healthy thoroughbred! Basically you have to short the ECM and follow the calibration steps. Just undoing the negative cable is not enough to clear the ECM. I have never heard of this before in all of my mechanic years. The link is below

How long have you been driving your truck since resetting the TSB? I have been having this issue for years and have been hoping someone would figure it out! I'm going to try it.

Still running good. One thing I have learned. It has to been done with the engine dead cold (overnight) It will not work if warm
