I Have A 2007 3500 Dualy 15,000 Miles . I Brought The Truck In For A Small Oil Leak And They Said It Was The Rear Main Bearing . Ok They Fixed That Now They Say My Turbo Is Leaking So They But A New Seal In That And Fix ,when I Got The Truck Home I Said To Myself Let Me Check The Oil And Transmission Fluid .
Well The Oil Was 1 Quart Low And The Tran's Fluid Was 3 Quarts Low
So Now 3 Day's Later I Have A Lot Of Vibration When I Take Off From A Start Only Threw First Gear And Also A Humming Sound Sometimes When I Take The Gas Off And Coast . So I Think They F*ck Up The Trans Now , I Feel They Are Doing Waranty Scamm Work .
Anyway Let Know What You Think About The Vibration And The Humming Noise .
Ow And Somtimes It Feel's Like Its The Front End And Other Times It Feel Like Its In The Rear .
Thank's Alot For Your Help

Take it to another shop

Get on The Diesel Place and find out which dealer has a REALLY good D/A tech. Not all of the dealers have experts; especially the D/A setup. Have the whole thing gone over.

I had to go through this on my last truck; a GM. It went to three dealers before someone really knew what they were doing.

THANK'S,, I BROUGHT IT TO A DIFFRENT DEALER THIS MORNING SO I GUESS I WILL SEE WHAT THEY SAY .
WHEN I TOOK THE SERVICE GUY FOR A RIDE ALL HE CAN SAY IS THAT THERE IS SOMETHING WRONG . COULD BE TRANS, GEAR CASE, DIFFRENCAIL,
I JUST TOLD THEM TO FIX IT
I'M SHURE I WILL GET A CALL LATER WITH THE NEW'S
THANNKS

Mike I have another friend having problems with the tranny on his Chevy.

Check this thread out and see if there is any information that may help you.

There seems to be an issue with a hole in the transfer case if I remember right.
