Hi. Last week my transmission started acting sluggish. When I switched from reverse to forward it hesitated. When I hit the gas to go, it acted like I was towing something very heavy. And when I go to pass it will not down shift. I checked the trans fluid when it was hot and running and it was not low. This might be connected, but my cruise control went out at the same time the trans problems started. Could this be a vaccume problem? Or fuse problem?

Have the Body system and the PCM scanned for codes, hard codes and ones in "freeze frame/failure records".The cruise and trans share a few sensors so if one fails it can affect the other
