Hello- I have a 2005 Dodge caravan... we recently started noticing that when we drive the vehicle in the 35 to 45mph range there is this strange bucking or hesitation when you have your foot steady on the gas. I had one of my buddies hook up the computer diagnostics to the car and he found no errors in the computer system for the engine or transmission or anything. It feels like if you were driving the car let off the gas and stepped on the gas again quickly. But at a high frequency... like every second or two. Lost on this one, I heard fluid, new trans, fuel filter, trottle cable.
Any help is needed first time user of site.

If the tranny is not slipping-check and test the following below.

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard.
