tranmission not shifting in any gear is it the range sensor

More likely transmission has failed internally .. Getting stuck - spinning wheels is 'very hard'on the transmission. No reason for a sensor to have failed - likely mechanical failure. Good luck with it!

As far as electronics your transmission uses a Governor pressure sensor and governor solenoid also a lock up and 3/4 shift solenoid. There's no EPC solenoid. Its unlikely a no move in forward and reverse is anything electrical in this unit. how ever you could have heated it up and stuck a valve int the regulator. We'd be happy to check it out and properly diagnose it for you and give you a few options to repair. Thank you Alan @ Everett Transmission.
