Assuming your transmission has one, it is possible the 2-3 shift solenoid or wiring associated with it is going bad. The low temps may be affecting the ability of it to fuction correctly.
A transmission professional would have to inspect and test it. It would be best to take it in on a sub-30deg day or leave it overnight at the shop when the next morning will be sub-30deg to ensure they can locate and replicate the problem.
One is IN the Transmission and the on the outside on the transaxle.
Your going to have to get your transmission rebuilt or get another put in.
Take a look at ripoffreport.com ( search cottman complaints ).
Automatic Transmissions are such complex things that I would leave that to a transmission shop to do or, if I needed a new Automatic Transmission I would purchase a used or rebuilt one and replace the bad one myself.
I had the same problem with my 96 Grand Voyager. When the transmission has a problem it will lock in first gear as not to leave you stranded in the middle of nowhere. There are electronics in the transmission and sensors that have detected a problem. I hate to say this but the transmission has to be rebuilt or changed.

Just rebuilt tranny on 1997 Town & country. Rebuild was $1,500.00. My buddy has a shop and he and I changed it, so not sure about install price. Bill
My 1997 Grand Caravan SE 3.8L w/169K just got a rebuilt transmission for $2495 at AAA. It's guaranteed for 3yrs Since the rest of the car is in very good condition, I thought it was worth it
