My 2000 nissan serena goes into limp mode after running for a while. Speed sensor seems to be malfunctioning.

SOURCE: where does the coolant go in my nissan serena.

The container you are talking about is called the overflow reservoir and yes, that is where you add the coolant. Make sure that your car has been off for a couple hours and is nice and cool before you try to add any, when it's hot it can build pressure and spray coolant or steam out when you unscrew the cap.

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.

There are two speed sensors one is called a revolution sensor that is located on the case of the transmission. You can take the driver side wheel off and see the sensor on the top of the case of the transmission. A 10mm bolt is holding it in. Easy fix

you replaced the output speed sensor, try replacing the input speed sensor, sometimes called the turbine speed sensor, thats where the computer gets the info to shift.
