When you push the pedal from a stop, it starts to go, then kind of hesitates. It sort of feels like it slips out of gear but, it is a pretty mild jerk and the truck drives great besides that.
Any ideas?
Should I wait for it to get worse?

 

Auto or stick trans?

 

welcome to the site . if you fill in your sig, we will know what kind of truck and the mods done to it,makes it easyer to help you out

 

It's actually something I might buy.
It's an auto trans and everything else is stock.(2wd)
This will be my first diesel. I've only driven a few so it's hard for me to diagnos or describe better just from taking it for a spin.
Not sure if the trans has had a rebuild and there is 180k on the truck.
Everything else is in great condition.
Hope this helps.
Thanks,
