So disappointed in this Diesel platform; wish there was a return policy.

Every car that I have driven with a sequential gear box has been pull back to go up. Push forward to go down. The 800HP track Viper I drove was a blast.

Lenco tranny's. You pull back for each high gear.

Liberty tranny's. You pull and push for each higher gear. Like a vertical shifter.

Hurst makes a vertical gate shifter to replace the H pattern shifter for the 4 speed manual transmissions.

I'm going to try a few things:
1. Relocate the horns that block the top right and left of the radiator.
2. Look at upgrading or possibly adding a secondary oil cooler. (maybe https://www.mishimoto.com/jeep-gladiator-performance-transmission-cooler-2020.html if it fits the ecodiesel)
3. Reducing weight as much as possible.
3.1 Replace my front steel bumper with a stubby aluminum one.
3.2 Try and lighten my trailer as much as possible.
3.3 Remove my back seats on trips.
4. Take it super easy on the throttle, go slow up hills when possible.

If that does not do it and I still find I have the same issues, I'll sell the truck.

Did you upgrade the air cooler?
