I have a 2002 chrysler concorde that was in limp mode so i replaced the input speed sensor and now it drives fine but the is another code that says shift solenoid a malfunction could that be caused from the car being in limp mode

Unfortunately, you should have gotten the diagnostic codes for the transmission before messing with the shift solenoid. Most of those dodge shift issues are caused by input and output speed sensors.

Beware speed sensors seldom fail. Chrysler products transmission have a limp mode where they only shift to second gear when something goes wrong and many times when nothing is wrong. If the speedometer fails it goes to limp. If an OBD scan gives a transmission code sometimes clearing the code will end the problem. When driving if the transmission shifts one time as it should the sensor is working.

Hello
The engine and transmission in this cars drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant teperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL THE DIAGNOSIS & TESTING IS COMPLETED.

You may need to have the transmission control module reprogrammed.

you need to have three sensors checked on the transmission,output sensor,input sensor,and speed sensor,
one is not telling the computer your speed,so the computer keeps you in limp mode

it is going in limp mode,
if your speedometer is not working will cause this,that would be a speed sensor,or the other two reasons would be the input or output sensors on the tranny

you should also replace the input speed sensor,they should always be done in pairs and i have had both of them bad on numerous vehicles,hope this helps

There is a faulty sensor or valve. Sounds like a valve. The best thing to do, is take it somewhere that can diagnose the trouble code. Autozone can I believe, and they can tell you exactly what's going on with it.

It sounds like it is in limp mode, this means that there is a transmission problem. The trans will go into limp mode to protect from further damage. You need to take it to a trans shop to have diagnostic test

try getting a new shift solenoid for it. i had the same problem on my 2002 chrysler town and country and my plymouth breeze which is also a dodge product. it is very simple to do and doesnt take all that long. the part will probably run you about 150 to 200 dollars but it should fix your problem.
