Truck shakes when accelerating

Its not the tires/wheels. Ijust had them balanced.

It only shakes when hard accelerating. If im easy on it, then smooth as can be.

It gets worse with the RPM of the engine. Im thinking its in the tranny.

It still shifts smooth and i have been pulling 17 mpg on the interstate with it. So i know its acting correctly?


Could i have blown something in the trans or balloned the torque converter?

It just started the other day, i drove about 350 miles on vacation and noticed it when i went to come home.

Like i said it only shakes when you lay in to the throttle, and it gets kinda violent.

Sounds like U-Joints but could also be clutch's in the rearend. Clutch's would really be noticeable when turning left and accelerating and when you first take off. Unless U-Joints are really bad they're not as noticeable on easy takeoffs, moreso on hard.

"Like i said it only shakes when you lay in to the throttle, and it gets kinda violent. "

related to engine power, not motor speed or ground speed... sounds like a COP failure ? no code?

It seems to be based on load on the truck. Only when i get on it hard does it do it.

The truck does not have COP's. It is a coil pack ignition system. Plugs are less than 30k.

My bet is that it's ignition related.

I have an 03 F150 and I started having similar problems a while back. For a few months, I noticed my truck would kind of "jump" when I was accelerating, but it only did it every once in a while. A few days ago though, I was on the highway trying to speed up and around 50 mph it started shaking pretty bad. I let off, tried to speed up again, and it shook again. So I let someone else drive it and they think it's transmission problems. It didn't shake as bad, but they said it's slipping in 3rd gear. I'm probably going to take it in tomorrow

Sounds like torque converter shudder to me. These trucks were notorious for it.

I had to look that up and now I know what that feeling was when I was a kid. A delivery place I worked had a Dodge Dakota that would shake at highway speeds, especially between 3rd and 4th gear. I bet it was the TC.

Mine shakes in every gear. But only when im accelerating or decelerating (when locked in a gear). When going constant, its pretty much smooth.

Does it do it while taking off from a stop under steady acceleration in a straight line? I say straight line to eliminate the chance of shudder from the LS unit...

Nothing to do with the LS.

I have determined that it is the engine missing now. Its very weird. I have been around these motors/trannys for 10 years now. I know my way around for the most part.

Haven t had these issues yet without a CEL. Im thinking its gotta be a plug/plugwire/ or coil pack. Well just see. Like i said, theres now CEL. no codes.
