why would you replace the transmission control module for these faults? if anything needs to be done first it is a comprehensive visual check of the wiring to the transmission.. a fluid drain and pan drop to see if any metal pieces are in the bottom of the pan. if no metal pieces are found and the fluid id still red and there is no evidence of woiring damage, then you have had a catastrophic failure of the valve body/solenoid pack and possibly the transmission.

Hi, My name is ***** ***** for the delay.

I will do my best to assist you.

Expert:  Tim's Auto Repair replied 26 days ago.

from the way you explain the problem,,you need to first check the wire harness and the wiring to the transmission for damage..if the wiring is good,i would think you will need to replace the shift solenoid body at the valve body
