Check Engine Light

Hello all, new to the forums.

I have a 2005 Kia Sedona with about 16,800 miles. Today while driving my wife heard a single click as we accelerated from a stop light. At the next light I heard it. At a third light I noted that the single click happened between 25 and 28 miles per hour. This trend repeated.

Suddenly, as I was accelerating at a light, the "Check Engine" light came on, then the engine would rev, but would not go forward. I had enough speed to coast into a parking lot. I shut off the engine, turned it back on, and could rev the engine while in gear, but it would not move forward.

I called the Kia roadside and got a tow to the dealership where we bought the van. I noted that the tow truck driver was able to back the van onto the flatbed. So, the transmission worked in reverse, but not forward.:banghead:

I would appreciate any insight as to what may have caused this or what the solution might be.

Thank you. Kia Sedona - 16800 miles, 8 months old, all required maintenance has been performed.
