I was traveling through New York pulling my 21 foot RV and and the transmission on my Chevy truck (83,000 miles) heated up, the engine light came on, the transmission message occurred, and stopped working. We were stuck on the side of the road. The mechanic said these 6 speed transmissions often fail and it cost me $11,000 to rebuild it. He said the torque converter broke into pieces and traveled through my transmission lines. Online I learned this wasa very common problems with these kind of trucks and suvs.
