Answer
Hi Clancey,
It sounds like your electronically controller transaxle has detected some problem with the unit and in order to avoid any unnecessary damage has gone into "limp-in" mode which means it won't shift out of 2nd gear. It allows the car to be driven at moderate speed to a garage for analysis. The controller logs the problem as a two digit number stored in its memory. The dealer or a competent transmission shop should have a readout unit to find out what the code number is and from that they can make some conclusions about whether the trans can be repaired without being removed from the car (for example a hydrualic pressure problem) OR if some mechanical damage is involved (follow  that up by dropping the pans and looking for debris to be present or not) which if true would require a pretty expensive rebuild, I am sorry to say.
So that is my best advice, go to a dealer and ask for a diagnostic readout and estimate for repairs. Get the code number(s) and if you like, write back with a follow-up question to me and we compare what you are told with what the shop manual says is the problem and decide if you are getting the correct advice. You don't have to give them a blank check, just ask for a diagnostic readout and estimate. It will cost something to get that done, but the more information you have before going forward the better.
