tranny?

[slc dzl]

so my truck is acting wierd it is a 2006 f250,
Just had the tranny flushed at 62000 last week, oil changed last week to.
So there is a vibration/grinding feeling in the accelerator pedal between 1000-1200 rpm in every gear any ideas?

So you only feel it in the accelerator pedal and not the truck or seat? What about the floor if you put it on cruise and put your feet flat on he floor? just sounds more like a bad U joint . If its the truck in your avatar you should have a one piece rear driveshaft so it wouldn't be a carrier bearing.

I agree with chappy. Check drive train components also check and see if your down pipe is vibrating on the firewall. Mine setteled and started vibrating on the firewall around 1100 rpms. Just a thought.

I was gonna say downpipe too, had a similar sympton after going through a big puddle, turns out the downpipe got pushed up against the bell housing.

 

[chappy]

Yeah I forgot about the down pipe.

 

[slc dzl]

Can feel it on the floor, I will look at the down pipe. thanks for the help

Down pipes can make some crazzy vibrations. At ideal or acceleration seen it both ways

When mine was against the bell housing it was worst at around 1200 RPMs but went away so I thought I had some real problems.

mine was rubbing on my frame when i did my exhaust vibrated pretty bad

Same here, mine would rub on the trans crossmember too sometimes.
