I am new to the diesel game and I want to give my 02 D/A a little more power. I pull a 12K 5th wheel and it is a little under powered on medium grades. My truck will not down shift to 4th or come out of T/C lockup so when the speed gets down to 55mph i manually down shift to 4th. I think there is something wrong but dont know what. With a little more power it may stay at 65mph and I wont have to screw around with manually downshifting. any help would greatly appreciated.
