Chrysler Repair: cirrus lxi 1995, cirrus lxi, detroit metro area

Question
Where in the Detroit metro area can I find a mechanic that fully understands a cirrus, with the ability to be able to determine if the speed sensor is the problem of my car getting stuck in second gear after functioning just fine in the highway, city driving if I tap the brakes while the transmission is engaged my car buckles and get stuck in second gear. I feel as if the engine is figthing against me or the brakes are on. Usually  I need to turn off the engine and get it going again to get out of gear. Once in a while the same problem will happen while I am in the highway in traffic. Please help my car is in excellent condition body wise except for this glitch.

Answer
Hi Walter,
Your trans is going into "limp-in mode" which is a default condition designed to use a minimum of internal parts of the trans until it can be diagnosed so as to prevent unnecessary damage. I would be inclined to go to a Chrysler dealer or an independent (not franchised) trans shop and have the transmission controller queried as to what fault code(s) it has stored in its memory. These codes hint at the solution to a problem but are often not exactly specific as to what to do (sometimes several possible reasons can cause a code but at least it limits the choices).
To do the readout the shop would have to have 6-pin body readout plug and either a Chrysler Diagnostic Readout Box II or its equivalent because that plug which is under the dash is specific for transmission readout access, and the system as a whole is called an OBD-I generation of on-board diagnostics. It should be under $50 for a simple readout and they might even agree to give you credit for the readout if you then authorized the repair. Once you get the specific code numbers, what they say it means, what they propose to do next, and a cost estimate...write back to me and we'll compare what they tell you with a Chrysler shop manual I have for that time frame of vehicle.
Take it one step at a time and don't get pressured into a rebuild which can run $1500, unnecessarily.
