Who sells this gauge pod? Not crazy for the 3 pod A pillar style.

With 1st or 2nd selected, the line pressure is higher without the throttle valve being stoked with the gas pedal. So at part throttle you will get full line pressure with part or no throttle unlike 3rd where line pressure is controlled by gas pedal position.

The trans pressure goes to like 250+ when in Manual 1st or 2nd, no matter the engine RPM. While in Drive it is dependent on the TV cable being pulled out.

The band is engaged when shifting 1-2 so the higher the line pressure, the better the band engagement around the drum.
