Chrysler Repair: Limp Mode no Speedo, chrysler cirrus, number translation

Question
Hi,
I have a automatic '98 Chrysler Cirrus that had a transmission rebuilt about a year ago.  This weekend the car started going into limp mode after coming to a stop or slowing down for a turn.  I have read some info on others you have helped and was wondering if you think the problem is with the sensor?  If so how can i find my sensor?
 The car likes to jerk when changing gears from a stop about once per trip (10 minute drive and usually at the first stop i make) and sometimes the car comes back out of limp mode after coming to another stop.  The trans itself seems to work smooth when its working right.  Is there also a on-off-on-off "on" sequence to get my codes for a '98?  i attempted it but to no resolve.  Please help before i take this demon back to the IT shop who did my work a year ago.

Hi Steve,
Oops, I just read the title of your question and noticed that there is "no Speedo". I had overlooked that! Certainly then the output speed sensor is a suspected culprit or its electrical connection. The sensor is located at the far left end of the side of the trans that faces the front of the vehicle, about midline on the body. It has a 2-wire connector with colors dark blue/brown and light green/ violet.
Once that sensor and wire connector are checked out and repaired I suspect the trans will run much better. If a readout is a cost factor, then I think it would be acceptable to check the wires to the sensor and the plug, and if those work out, then replace the sensor. The other ends of the wires are at pin 13 and pin 14, respectively, of the trans plug, if you want to verify the connections. (These numbers are based upon the '96 shop manual that I have).

Hi Steve,
The transmission controller has a separate memory and code number translation table than the engine controller. It has not been ever possible to read out transmission fault code numbers without a code reader device to plug into a socket under the dash. So the only way to get diagnostic help for a trans limp-in situation is to have a shop with the appropriate reader for the trans controller do the readout. Once you get the code numbers, and names, ask what the  repair will be, and how much is the estimated cost. Then let me know and we can compare notes with the shop manual.
I hope that the trans is still covered by a warranty on the earlier rebuild.
I can't comment on whether the issue is due to a sensor problem. It is guessing to do so. So let the shop do the readout and suggest what they will do (at their expense, or at your expense) and if you aren't satisfied or certain about the proposal write me with a report on the readout.
