car wont shift out of park on 2002 Ford Escort

My automatic will not shift out of park. I've had it checked, it's not the sensors. It may be the transmission but I can imagine what. Can't tow cause I can't get it to move an inch.

there are no sensors. if it is the interlock, it could be the brake light switch or the the solenoid. if not, then the cable could be frozen and need to be replaced.

it can be towed. they have to manually shift the trans out of gear.

How much should it cost to replace the shift interlock solenoid? The mechanic said the part is $194.95 and 2 hours of labor is 345.43.
sounds high. shop around for pricing. try a trans shop for pricing as they are very familiar with this repair.
