Truck is wobbling I finished rebuilding my 4L60e transmission a few months ago. The truck seems to be shifting fine but I have noticed that I can feel the truck wobble in low Rpms while slowly moving or stopped. What could this be?

I'd put both a 20 ounce bottle of TECHRON fuel system cleaner AND a 21 ounce can of Berryman's B-12 Injector cleaner in the fuel tank, replace the fuel filter ( if eqipped) and put NEW spark plugs and spark plug WIRES on, and than dispatch the nearest teenager with a license to drive it down to the store for a loaf of bread and have him also route past a particular gasoline station 20 miles away to fill up the tank. Be sure and instruct Teenager to "Drive Very Carefully, as you are breaking in a new transmission "...
My bet is that it idles REAL smooth after a good Italian Tune Up.

That wobble at low RPM is likely the torque converter. It could be a bad converter or it wasn't fully seated against the flexplate during installation. Check your converter bolts for proper tightness and make sure the converter is fully engaged. If the problem persists, the converter might be failing.
