Low line pressure after torque converter replacement?

[Meat27]

i'm wondering if maybe the pump was damaged on install. your pullout is good, but I always measure from the bellhousing to the converter pad vs that "3 click" nonsense. the measurement should be about 1". I would maybe start with the pressure regulator in the pump, maybe a piece of trash is stopping the valve from moving.

PS: do not drive the vehicle until you get the pressure issue sorted out.

Debris affecting pressure has been the problem. Not so much in the Pressure Regulator valve. But I keep getting trash in the EPC solenoid screen, reducing the signal to the boost valve. There was no trouble with trash or pressure before the TC replacement. But debris must have been broken loose during the TC replacement. It’s a first for me.

I haven’t known if that was a possibility. Sure seems like it. Brand is Power Torque from O’reilly.
