2002 Dodge Grand Carvan sport..... I have replaced: TCM, Speed Sensors, and still in limp mode. Speedometer jumping like crazy. When I get to 2000 PRM seems like it goes into neutral if I let up gas and apply then will speed up.

Regarding the Check Engine Light: Do you have a Digital Odometer? If So with the Engine Light ON = you have a Code. Insert the Key in the Ignition. Turn the Key three (3) times from OFF to ON (not Start) which is the position just before Start. On the third (3rd) time leave the Key in the ON (not Start) position. Look at the digital odometer space. Write down and Codes that are present. For Example "P 0430". The last code will be "donE" = it is done giving you codes. Respond a Comment back to this Post and let me know what Code(s) are showing. I am assuming you have a 4-speed transmission?
There are 2-speed Sensors on the front of the transmission. Input and Output Speed Sensors.
They are level with each other, right above the top line of the Solenoid (wiring harness goes into this box-like assembly) The one that is closest to the Solenoid is the Input Sensor. The one (at the same level) towards the left side of the van is the Output sensor. The Output Sensor is most likely malfunctioning. Unplug this and ceck the electrical connnection. Remoe and corrosion or oxidation (white stuff) from both sides of the metal connections. Replug in and check operations. Because of it's location, these Sensors are prone to corrosion and oxidation. If that does not work: Unplug again and remove the Output Sensor. I believe a 1-in wrench or 1-inch Deep Socket will work, after you unplug the sensor. Before replacing the sensors - you may clean the metal particles off the interior tips of the Sensors and reinstall and check operations. IF this does not fix the problem: Unplug, Remove and Replace this Output Sensor.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!

Change the output speed sensor as well and clear the vehicle codes either via a scanner or disconnecting the battery.Also make sure the transmission is at the proper fluid level.

you don`t say if you ever had codes pulled from the tcm or if you installed a new tcm and not a used one.if a used one you may have a bad one.also you may have to have the tcm programed to your vehicle.if in limp in mode there possibly a problem internal to the transmission.you need to have it checked out a tranny shop that you trust or is recomended by several people.

The output shaft sensor is where the TCM gets its info. And what the speedometer runs off of. It is best to have a diagnostic ran on this first. But shooting from the hip, I would go for the output sensor.

How do i get my 2000 dogde carvan out of low gear

I'm guessing that the problem you have is the van only has 2nd gear. This is limp mode. You need to have the Transmission control module scanned for codes. You likely have a bad speed sensor. Does the speedometer work?

Speedometer quit on a 2000 intrepid. And it quit shifting gears at the same time

A common issue are the input and output speed sensors.When bad they cause the vehicle to go into limp mode keeping it in second gear and speedometer sometimes no longer works.

no codes found because your checking the PCM,
your problem is you need codes from the TCM,the computer for the transmission,since you replaced the speed sensor the other two things that affect a speedometer and transmission are the input and output sensors,they both screw in the transmission.
