What's my best bet replace the sensor or replace the whole transmission it's a shifts sensor?

I guess it would depend on how many miles are on the car.

If its low miles, then I would replace a few on the solenoids and do a shift kit and be on your way.

If you have high miles, then a full rebuild would be a better idea because likely everything else is worn out.

Low miles so if they switch em what else has to be done
