Hook up an OBD-II reader to your truck and pull the fault readings.

Once you get the fault readings, you should be able to locate the source of the problem.

In the meantime, you can subscribe to online service manual sites at Chiltondiy.com, autozone, alldatadiy.com, RepairSolutions(Innova) where you can get and download your vehicle specs and input fault codes.

If this is a serious priority, go to a reputable ASE certified transmission shop- at the very least, pay them to diagnose the problem and if its something you can repair yourself, at least you monetary losses are negligible.

You already wasted time and money trying to repair the problem in guesswork.

BTW, talking off the top of my head, it could be a bad transfer case control module or a wiring fault.

If any lights on dash first check why. If not try cleaning your throttle body. A dirty butterfly will give wrong TPS readings and cause late shifts around 3000RPM

You are expecting a lot from a torque converter to full 2.5 tons at 60 mph. The converter will be a standard unit and will experience considerable slip under these conditions .Run fault codes to ensure that the converter clutch is operational. Talk to an auto transmission shop about a heavy duty converter that is more suited to the job.

DTC P1516 Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance

Your vehicle has an electronic throttle body unit so it uses voltage signals to control throttle blade in the throttle body. There are a few different issues that can cause this problem.

First off there is a update for the PCM to address those codes, but you will have to take it to the dealer for that.

Second there is issues with the actuator on the throttle body binding up and causing the codes.

Third there is a yellow wire coming off the throttle body connector that breaks inside internally and cannot be seen to the naked eye. The best way to test that is to grab the wire about 5 inches from the connector and tug if it feels spongy or breaks, that

Go back to the alternator for the problem as it is connected directly to the battery via the cable. Alternators charge rate is 14.5 to 15.5 volts and if it is only 13.8 volts then that is battery voltage for a good battery and this means that the alternator is not charging which indicates a diode has failed and discharging the battery
