The TCM was replaced because the transmission was not shifting out of first gear. After it was changed the speedometer stopped working. Could the TCM need to be reprogramed? Also, the back end always seems to be fishtailing when the car is moving. Are their rear sway bar bushings in the back that could cause this?

Yes, needing to adapt ( program ) the TCM to the vehicle is possible. I would take your vehicle to a good shop and have the rear checked out ASAP, this does not sound safe.

I need to ask a ? my 2001 Dodge Caravan is having trouble shifting, it will almost shake when we go to slow down and stop and then is having trouble going into Drive and we would have to put it into 2nd to get it going good up to about 50-55 mph and then put it in drive and then it does great...some say the transmission needs replaced but others say no it is something minor because there is no smoke at all coming from the exhaust pipe...someone said switch plate, but when I seen your ? about a TCM and you was having trouble shifting was wondering if that could be my problem and if it cost a lot..should maybe think of trading it in..though I love my Dodge van...
