Your car uses a 3 speed transaxle that has a semi- mechanical up shift system. But if it does not upshift and the fluid is full and very dirty, expect trouble. Most likely the problem is internal. A kickdown band in the transmission must apply for second gear. There is a remote possibility it may be repaired without removal because a cable could be causing too much pressure for an upshift to occur.
They sell Chrysler remanufactured transmissions for a pretty decent price but make sure the rest of the car is in good shape before you put a lot of money into it. 100,000 miles is a lot for a 4 cylinder. Expect the worst, sorry. Bring it to a Chrysler dealer. They see this all the time and will know what is best for you.
