1999 Intrepid/Speedometer Not Working/Transmission not shifting
I have a 1999 Dodge Intrepid. On Friday, we began experiencing the following problems:
1. Speedometer not working
2. Transmission not shifting
3. Stalling when coming to a stop
4. Check Engine Light (this disappeared after I disconnected/reconnect battery). It may come back though as it has intermittenly been on and off.
I had it scanned at Firestone and got the following 3 errors, but they said I need to take it to a transmissio shop.
DTC P0731, P0700, P01790.
Reading this forum has given me ideas of what can be wrong but I still have some questions:
Could this be a Transmission Input/Output sensor? Speed sensor (or is that the same thing?). A bad TCM?
Any help would greatly be appreciated.
Thank you. Steve
