i have 06 F150 5.4. Has about 160k on it. For a while the trans would skip or buck between gear wen cruising . The other day I was driving and it just stoped all togather. When I turn over drive off I can drive fine but will not go out of 2ed gear. With the od on it drive fine till I hit 35-40 mph and then acts like it is in nutral. If I really give it a lot of gas it will catch for a second and go then kick back out but still will not go to 3rd. I changed the fluid and filter and was no diffrence. I took it to a shop and but a big computer in it and it has thrown no coads at all so there is nothing to read. Wondering if it could be a speed sensor or if I’m looking at a new trans?

 

@jON39 you need a different shop if they "put a big computer on it and there is nothing to read".


Our trucks provide a wealth of OBDII information on the transmission. There are somewhere around thirty parameters that can be read with a capable live data scanner. Such as 'commanded line pressure', 'line pressure', input shaft RPM, output shaft RPM, calculated gear ratio (Input-to-Output), solenoid status, Torque converter slip, gear number, and on and on. If you have Torque Pro App - I can provide you about 30 custom PIDs you can input into Torque and read yourself.


Edit: Add Screen capture

I do not have that app but I will try maby a dealer? This was a ssnapone one but I’ll try that thanks

 

Sounds like what mine did @ 160k. I had to have it rebuilt, there were internal components that crapped out. Good luck, hopefully it's something not as bad.

 

Time for a new/rebuilt transmission.

 

The same thing is happening to my 2004. Shop said the tranny needs rebuilt or replaced. So I’m replacing the tranny and everything else with a new F250.

You have a direct clutch problem. Only way to fix it is to rebuild or replace.

 

Find out where your local municipality takes its vehicles to have trans work done and take it there. You probably need a rebuild.

 

You broke the overdrive band and the trans should be rebuild. Did the same thing on mine at about 185K.
