4R100 PWM/NON-PWM
I have a 2001 Superduty 5.4 with an Automatic. Will a 7.3 trans with PWM lockup converter work properly , if plugged into my PCM? I'm not sure if a 2001 5.4 4r100 has PWM or NON-PWM lockup. Thanks

I'm hoping the gas PCM will shift it properly . If not, will I just change the pump and solenoids to the non-pwm?

Change the case, too. A 7.3L case will not bolt to a 5.4L.

Yes, thanks. I'm thinking of installing a diesel engine with my current PCM. Will the gas PCM control the transmission , properly?

A gas PCM can control a diesel transmission, as long as it is also controlling a gas engine. Without an engine to control the PCM will not control the transmission.

You could get an IDI transmission controller. Or you could get a controller from PCS.
