That is a seemingly common misconception. The purpose of the valves is to operate the EGR valves. However, if the valves leak, the operation of the transmission can be affected. So, folks replace the valves, then the transmission shifts better. So they conclude that the valves operate the transmission. (This applies to the subject vehicle; other models are different.)
