Struggle

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?

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.

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'?
