Just replaced the transmission in my 2007 4x4. A lot of things went back to working like the exhaust brake, etc. Of course, a lot of things went back to not working - tail lights stay on, engine light on, etc. etc. Everything seems to be related to the electronics on the truck. Question: am I supposed to now take the truck to the dealer to have them "read" it again ? or is there something we should be doing now that the new transmission is in??
