Is you check engine light on? If so have codes pulled. Sound like your tranny is in what is called limp mode, which the vehicle is still drivable to get it to a shop, you just cannot go faster than about 25mph.

It could possibly be the Turbine Speed Sensor and the Output Shaft Speed Sensor. The cost for the 2 of them should be under $40 and here are there locations....

I have the same issue on my 2000 Dodge Intrepid 2.7L V6. I have replaced the speed sensor to no effect. I haven't seen anything before about a Turbine Speed Sensor. Is this also referred to as the Input Speed Sensor? Is it possible that the wiring to the Output Speed Sensor could be part of the issue? If so, how and where does one test the wiring?

Thank you for the internet diagnosis. I was with a friend and his mother in Eastern Wyoming when the speedo, odo, check engine light problems arose. The car would also not shift into fourth as it was in "limp" mode. Instead of getting codes from the only shop in town (expensive) we drove to Checkers in Cheyenne (we were lucky to find the censors mentioned above in two stores). After an hour under the car replacing the censors all was well.

Thank you for the help.
