I have replaced the input speed sensor, the output speed sensor and the Transmission Solenoid Pack. I unplug the battery for a while and the check engine light turns off. I drive it and when the transmission is supposed to shift, the check engine light comes back on and it doesn't shift. I know it is in "limp mode" but I don't know how to get it out. Thinking of changing the filter and oil as well as the Transmission Range Sensor. Will this help?
You cant get rid of the issue until you find the cause and fix it. i would not recommend throwing any more parts at it, get someone with a scan tool and see what codes are there before you waste any more money

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.

The input and output speed sensors look identical on the connector side. The one over the solenoid pack is the input, the one closer to the left frame rail or left front wheel is the output sensor. I hope this helps.

This might sound odd, but it could be the gearbox output shaft bearing. If the transmission sounds noisier than it did, this could be the issue. Only way to check is to take off the transfer box. Not a major job, but takes a while. Some good fault code readers will read transmission codes, and allow you to see in real time what the sensor is doing - if the sensor suddenly loses signal, then it is very likely to be the a bearing (output shaft bearing most likely) that is at fault, causing the sensor ring to move too far from the sensor. Best guess, but could be other things, so don't go taking that transfer box off without getting a road test with a good fault code reader on it - or find someone with a portable oscilloscope and put that across the sensor - you should be able to see nice square wave pulses - if they get bigger and smaller (variable amplitude), that's your problem. If not, the fault lies elsewhere.

1997 dodge truck 4x4 shifts good when cool but not when warms up, is it the shift solenoid?and how much is it too fix it?
