Thanks again..
I have an appointment Thursday,service manager said bring it in so they can check the drive train for codes ,mention to him it shifts sluggish,late shift..and noticed Tran tempt was around 190plus ,,this is after driving on the highway for 3,4 hrs ,I’m sure they aren’t gonna go for a long drive to try to duplicate the complaint,truck still under drive train warranty,asked if there was any bulletins on issue,he checked with someone there and came back saying there was none.just don’t want to throw $125 out the window for a dia..problem not found at this time lol ,any advice would be great .thanks again Scott
