Chrysler Repair: 1994concord transmisson wont go into OD, gear shift linkage, clutch problems


Question
 

Answer
Hi Rick,
The troubleshooting table for trans says that it could be a misadjusted gear shift linkage, or internal clutch problems. The latter of course means a big repair bill if true. After verifying the shifter is adjusted I would suggest that you get a fault code readout of the trans controller memory so as to see if it could be a problem that is repairable without removing the transmission.
The transmission controller logs the problem as a two digit number stored in its memory. The transmission controller does not have a self-read capability so you can't use the ignition switch to get the codes.
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 electrical or hydraulic pressure problem) OR if some mechanical damage is involved (but follow-up a "mechanical damage" diagnosis by dropping the oil pans and looking for debris to be present or not) which if true would require a pretty expensive rebuild, I am sorry to say. No debris in the pans would suggest the possibility of an hydraulic problem only.
So that is my best advice: go to a dealer/independent and ask for a diagnostic readout of the transmission controller and an estimate for repairs. Their readout instrument must have a 6-pin bus diagnostic connector and the appropriate software to do the readout properly. The socket for the plug is under the dash so you can compare their plug with your socket if it isn't a dealer.  The Chrysler unit is called a DRB II.  Get the code number(s), and if you like, write back with a 'follow-up' question to me and we can compare what you are told with what the shop manual says is the problem of that code, and then decide if you are getting the correct advice. You don't have to give them a blank check, just ask for a diagnostic readout, the code numbers and the repair estimate. It will cost something to get that done (should be under $50), but the more information you have before going forward the better. I would not go to a franchise-type (AAMCO) transmission shop, but rather an independent with a good reputation or a Chrysler dealer. The place has to have a code reader with the 16 pin data link connector that mates with the Chrysler-type readout plug under the dash to the left of the steering wheel on the right side lower edge of the junction block/body computer module. So inquire whether that is true and if their reader can readout the transcontroller codes, if you don't go to a dealer shop. If you go ahead with the repair, the cost of the diagnosis is often credited against the repair cost. But don't rush to judgement because a total rebuild costs about $1,500 so you don't want to authorize that unless it is the only possibility. Let me know what happens, because the feedback helps me too.
The shifter adjustment procedure depends upon whether you have a floor or column shifter location. If you want to do it yourself tell me which one you have and I will copy the instructions from the manual and U.S. postal mail it to you. Give me a mailing address.
