What is the issue you are having?
What engine does the 2005 have?4.2L
Does it stumble on acceleration or at a steady cruise?Where did you get the coils?
Does it do it if you accelerate around 30 to 40 mph or does it do it from a stop and then accelerate?
Ok, I have seen this in a few F150s. The problem is in the transmission, caused by the torque converter and the TCC solenoid for the torque converter. It is not caused by the engine. The problem is that the TCC solenoid it trying to apply the torque converter and it is slipping, or shuddering when you accelerate under load, especially uphill. You will need to find a repair shop that has a scan tool that can monitor the TCC Solenoid Actual PID and the TCC Solenoid Desired PID that the PCM (Engine Computer) monitors to apply and release the torque converter.
Actual is what is happening at that moment and desired is what the PCM wants to see. Most shops should have one. And yes, they will need to drive it with the scan tool connected to actually see it. You can try the transmission fluid exchange. It may fix it, but it is a 30% chance, especially with 101,000 miles.
Yes. But I would like to see it verified instead of a shop throwing parts at it.
No, I doubt it.
I have heard that about other dealerships in my area also. They blame the simple things instead of properly diagnosing the problem. Way too many parts changers in the auto repair business now days.
Is it a 4x4 or*****
The torque converter and the TCC solenoid are about 7 hours labor. Not too sure on the price of the parts. Probably about $600 in parts. But that is a guess right now.
You can print it out. I cannot send a transcript.
Your very welcome. Good night.
