If this is the 4-door sedan model, Chrysler has been famous for having really good parts interchangeability between models and years. The coupe model is a different story as there was no other model similar to it.
There's two things to get us started. The first is a more detailed description of the symptoms. Which electrical circuits are you working in, or which parts are you looking for? Was the damage due to mice, a crash, or something else? Next, we need to know which transmission you have. The less-common was the really tough three-speed automatic. If you have the A604 4-speed, there will be a circle around the "3" on the shift indicator.
Chrysler's 4-speed was the world's first computer-controlled automatic transmission. As such it can store diagnostic fault codes, and the computer will put it into "limp" mode to allow you to drive it slowly to a repair shop without needing a tow truck. In limp mode it stays in second gear. You can also shift to "park", "reverse", and "neutral". The only way to get it out of limp mode is to turn the ignition switch off, then restart the engine. As a general rule, if it goes into limp mode right away when you shift into "drive", it is typically electrical-related, such as wiring, connector terminals, or electric switches and solenoids. If it starts out in first gear like normal, then bangs back into second gear while you're moving, it is more likely to be mechanical-related such as worn clutch packs or leaking seals.
The second item is to read and record any diagnostic fault codes. Chrysler made doing that yourself much easier than any other manufacturer, but it only applies to codes in the Engine Computer. To read them, cycle the ignition switch from "off" to "run" three times within five seconds without cranking the engine. Leave it in "run", then count the flashes of the Check Engine light. There will be a series of flashes, a short pause, then another series of flashes for the second digit of the code. After a longer pause, the next code, if there is one, will flash the same way. If you think you miscounted, turn the ignition switch off, then back to "run" one time. That will start the sequence over. Code 55 means it's done flashing codes.
On '96 and newer models the codes are three-digit and are read in the odometer display. If code 700 shows up, that just means there are other codes that need to be read in the Transmission Computer. '92 models don't show that with Engine Computer codes. You have to access the Transmission Computer, then read the codes directly. The people at most auto parts stores will read codes for you for free, but they use relatively simple code readers. Many of them only access Engine Computers. Some of the better ones can access Air Bag and Anti-lock Brake Computers, but not all of the other computers. If that is the case, you'll need to visit an independent repair shop, or the dealer, with a full scanner to have transmission codes read. Be sure to record the code numbers and list them in your reply.

to see the definitions, or I can interpret them for you. Be aware the people at auto parts stores are in the business of selling parts, but no diagnostic fault code ever says to replace a part or that one is defective. They only indicate the circuit or system that needs further diagnosis. When a part is referenced in a fault code, it is actually the cause of that code about half of the time. First we have to rule out wiring and connector terminal problems, and mechanical problems associated with that part.
Let me know what you come up with.
