When driving all the transmisson gear indicator lights will come on and the transmission will drop into lo gear and stay there for a while. when I stop and shut of the car and re-start it every thing will reset it self.some one told me change the transmisson control moduel.
The control module may be at fault, but more likely it is one of the electronic sensors that has detected an error condition or has failed completely. The transmission is programmed to go into "limp mode". This is actually 2nd gear (not 1st), and is intended to only be used to get the vehicle a short distance to get it serviced and save you a tow. The fact that it resets itself means the problem is intermittent so will not be easy to diagnose without the correct computerized tools to query the module and see why it took that action.
Are there any other symptoms when this happens? In many cases the speedometer also fails at this same time and this indicts the output speed sensor. When was the transmission fluid and filter last changed? How many miles on the vehicle? Other info might help to determine if a fluid and filter change might also solve your problem. If you have recently changed the fluid/filter and have no other symptoms, then take it to a competent transmission service place that knows how to service Chrysler transmissions (make sure they know Chryslers since they are different and REQUIRE special fluid) or a Chrysler dealer.
