If it was the trani I would be waiting to hear you say something like it slams into gear or the RPM's go up but the speed doesn't follow. you can try to shift it in low and manually shift it up as needed. It could be that your truck is not starting out in first but rather second. Am I on the right track, is this what your trying to describe.

replace fuel pump relay. check all fuses to ignition and pcm .make sure they are not loose. check coil wires make sure they not loose.look at battery if you have the ac delco seal battery make sure green eye still there .if its black have battery check out.

I would suspect a faulty EGR valve, but is the check engine light on? If it is, take the vehicle to an autoparts store and have them use a scan tool to retrieve the fault code(s) stored in the computer. Most parts stores offer this service free of charge. That will narrow the search for the problem. Sure hope this helped.

Try getting your transmission solenoid replaced. After I got mine replaced it ran fine after that. That's the exact same thing my Lumina was doing.
