Hey guys new the the forum and need some advice. My 06 f150 has 70,000 miles on it and recently started to shutter in OD under a slight pull until it downshifts. Would this mean torque converter slipage?

 

Maybe. It's more likely a low grade misfire, 70k is about when the OEM plugs start to get cruddy.

Have you ever had the trans fluid completely exchanged?

 

No I have not but plan on starting there. I will also change the plugs too

 

If you have a 5.4, make sure you know what you are getting into before you change the plugs.

A complete fluid exchange requires a machine - you don't have a torque converter drain plug.

 

Mine's got roughly 77k miles and it's acting up badly. It shutters, slams into the reverse gear, slips like crazy from a dead stop and then slams into gear, it cant decide which gear it wants to be in and surges between two gears, and it makes a noise like a turbo is winding up when I put it in park or neutral. Yeah, it's got some problems.

 

Just to give an update, I took it to the local shop and after they dropped the tranny they found a cracked drum. How the hell that happened, I have no idea. It's being rebuilt right now and after it's all back and running, I'll see if I still have a skipping problem.

 

Cracked Drum??? do you have any updates?

 

my 06 trans went out twice first time around 70,000 miles second was around 75,000 miles. but before that was the throttle body, abs, the window controls, and the dash. bought it with 55,000 miles on it.

 

mine surges or feels like its jerking when im lugging it while pulling a trailer.it dont do it when im not pulling a trailer,but like said above once it down shifts it dont do it?

 

They said the clutch drum inside the tranny had a crack in it and was causing it to lose pressure, thus giving me my problems. Is that a legitimate cause for how mine was acting, I have no idea since I don't know much about transmissions.

 

I just had my transmission rebuilt because of the exact same issue I was told that it was the valve body losing pressure between third and OD while this has almost completely fixed the issue it has still shuddered a couple times since I have had it back I don't really know what to do because its not doing it very often but it still has a issue and I want it taken care of while its under warranty but I am sure there gonna tell me they cant find anything wrong with it this is my first ford and I love the way it drives but If I cant resolve this issue I think it will be my last I have read a lot of people having the same issue the shudder between 3rd and OD under light load at low rpm.

Space bar break on ya? haha

 

Responding to a question that was one humongous runon sentence. Difficult to read without punctuation.

 

I have 140000 mine I don't know if the plugs have been changed or not. It doesn't feel like a spark plug issue to me I know alot of people on here suggest that but I can't see why it would only do it between third and over drive. I am thinking about giving it a try but its not throwing any codes and I hate to just throw money at it hoping and guessing what the issue is. I have seen alot of people having the same issue as me I just wish I could find someone that's has sucessfuly fixed the issue.
