The speedometer may become inoperative due to a failed vehicle speed sensor (VSS), . A failed sensor will require replacement.

I have 2003 Town and Country. 3 days ago wife started car and the belts/transmission were making a loud whining noise and got worse when we would turn the steering wheel. While driving right after that the transmission was trying to shift gears at stoplights. I then noticed the speedometer was bouncing between 5 and 20 mph. The whining has since reduced to a lot lower level but the speedometer still bounces around and occasionally tries to shift gears at a stop. I replaced the output speed sensor according thinking that was it based off the trouble codes "P0700" and P0720". Other error codes present are "P0134", "P0135", "P0420", "P0442" and "p0455". I am more concerned with the Transmission Control Module faults than the other ones right now. Should I replace the input speed sensor or the Transmission Control Module next?
No speedometer,no cruise,not shifting into 3rd at times
