I have noticed on my truck at certain low speeds I get a vibration in the pedal while driving very easy.

Has anyone else noticed this?

I am still a long way before no warranty but was wondering if this is just normal engine vibration transfered from the trans-auto/engine.

Thanks

 

Sounds like mine too. . Maybe it's a Northwest thing..........Where are you in the NW?

 

Northwest Iowa, outside of Sioux City area

 

What truck do you have struggle? There is a TSB for the 03 to put a "dampened" hydroboost line in. I have an 04 that does not have the weighted line and made a weight myself. The dealers around here wouldn't honor the 03 TSB on my early 04.

 

I have the same problem,tried everything,I cannot figure it out PLEASE HELP 04 1/2

 

Since the throttle is "fly by wire", what you are feeling is the servo to the TB actually throttling down at the shift point. It feels like a vibration, but it is normal. They had to derate the engine at the time of shift so the tranny doesnt explode.

 

I have the same issue and posted about it a while back.

 

Unbloody believable..... The mighty 5.9L cummins will and should vibrate by applying go pressure to the go pedal. If you feel a vibe at 1900-2200 rpm and don't wnat to fuss tie wrap the hoses. Vibrate? we are talking 300+hp/555tq heel yeah that's power! Tell me again why yuppies drive a cummins?

Why are you castigating everybody by referring to them as "yuppies"?

May I suggest that you 'git a life'?

 

Step on the pedal harder and you will never feel it!!

 

I think it's just anxious to get somewhere
