The truck is a 2007 2500 mega cab 5.9 auto. I just bought this truck. It doesnt seem to do this when i first get in the truck from sitting awhile. When I take off from a dead stop the truck will not go for a few seconds then finally kicks in and goes. There is also quite a bit of driveline vibration going on that may or may not be related. I checked for codes and nothing comes up. Please help.

I have a 2004 5.9 auto with 300k on it. All factory, and had the same issue after moving from Texas to northern California, and i found it to be the crappy fuel they have in cali. if i get a tank from chevron and use a good fuel additive that the issue fixed itself.

Your transmission may be in limp mode. This can be caused by a bad solenoid/sensor combination. I experienced the same thing - and only later realized it was because it was starting out in 3rd - aka limp mode.

Stop driving it. Check out the solenoid/sensor. I had the same problem just after buying mine. The dealership may have erased the code before selling it to you.

Check out my thread on this. I still haven't figured it out...
I believe it's titled: lacking acceleration from a stop

Usually this is the TC draining back. Put it in neutral for a minute or so before taking off. Do you mean it does or doesn't do do this after sitting for a while?

It makes a huge difference when this happens and whether it is in gear or park. Clarify a bit better.

There is also quite a bit of driveline vibration going on that may or may not be related.

This could be ujoints, center support bearing on rear DS (if you have one), transmisison problems, t-case, or injectors. Not enough info to even guess start checking things in the drive train.

It does this when im in gear.

It does this when im in gear.

If it is worse when warm, plan on a trans rebuild. With the noise and this behaviour I would guess you have some internal damage. Dropping the pan checking what is in it, fluid coloration, and the filter will tell you more.

 

[spincksten]

No noise at all.

No noise at all.

Vibration then?

 

[spincksten]

Yes vibration pretty bad in steering wheel and seat.

 

[cerberusiam]

I would suspect the transmission as the source of the vibration and weird behaviour.

 

[spincksten]

Im going to drop the truck off at reputable trans shop and have them check it out. Ill post results

Well I got lucky. It ended up being the gov pressure and transducer solenoids. Also my ujoints in the rear shaft were shot. It rides and shifts like a new one now.
