    Hi All,

    06 Silverado 1500 5.3

    When I accelerate from a stop, tranny shifts fine. If I give it a little extra gas, or hit the gas hard, I'm getting a clunk and it sounds like something under the passenger cab of the vehicle. The truck shifts smooth, does not slip and runs great. Only annoying thing is this clunk that sounds like my truck body is going to fly off the frame!!!!! I do not feel anything in the steering column. Any thoughts?

    Thanks all for the replies. I contacted a mechanic today and described what's going on. Within about 30 seconds he said "yoke" to me. Advised its a common problem in the Silverados. Quoting 200 for the part and 125 for labor.

    Just got back from the dealership. The Slip Yoke needed to be lubed. It corrected the issues.

    Cool, that was an easy fix. Not too expensive either. Thanks for keeping us updated..
