The VSS sensor is located on the transaxle .
If the VSS is defective replace the instrument cluster

SOURCE: Dodge Durango 1998 5.2L Output Speed Sensor code P0720 Location

Its in different locations depending on if its 2wd or 4wd. For 2wd its in front of the drice shaft or for 4wd its in the tranfer case, just look for a white shape like box with wires plugged into it and you need a socket to remove it, iam not sure how much it is to replace as the cost varies at different shops.

SOURCE: FINDING THE LOCTION OF INPUT SPEED SENSOR ON KIA

The speed sensor is located on the right side facing the driver side. It is on the transmission under the air filter and air line that leads to the intake manifold. It is on the left side of the transmission. It is not on top of the transmission but on the left side of the transmission close to the firewall. It is best to raise the car and locate it from underneath.

SOURCE: check engine light code P0720...failed output

The output shaft speed sensor lets the computer know how fast you are going down the road to help it pick gear change points..
Yes, you can buy one and replace it.
First check the wires and plug going to it.
Your manual will probably describe its location better than me, but it will be toward the rear of the gearbox and usually has a small gear on the end that meshes with a mating gear on the output shaft as you put it in.

Po715 automatic transmission most of the time it don't want to go to the other gears stays in first gear

This is cause by three things. 1. Low fluid causing difficult shifting. 2. Bad electronics in the 1,2, shift circuit. Or the transmission is in limp mode. The transmission can go into limp mode for several reasons. Try removing the gas cap, sometimes the evap system will cause issues. Also get the car to normal operating temperature and check the trans fluid, add as necessary, do not overfill.

Can I replace the transmission solonoid on a 98 Town and Country Van without resetting the computer?

It depends. Are there codes in the computer now? Has it bee reset since you replaced the input speed sensor? If the codes are still in there, the transmission may still be in limp-in mode.

Your transmission is computer controlled. Trying to diagnose or repair it without the ability to interface with the computer that controls it about the same as surfing the internet with no monitor. If you push the right buttons and click your mouse just right, you might get to the page you are looking for (not likely, but possible). However, when you do get there, you still won't know it....

My dodge caravan 3.3L shows 5 malfunction codes what do they mean po455 po846 po500 po700 po732

P0455 = Evap leak monitor large leak detected.
This code usually means the gas cap may have been loose or needs the rubber gasket.

P0500 = No vehicle speed sensor signal.
Vehicle speed sensor is located on the transmission near one of the axle shafts (it may need replacing).

P0700 = EATX controller DTC present.
This simply means you have transmission related codes.

P0732 = Gear ratio error in 2nd gear.
This code is of some concern, it means the transmission is slipping in 2nd gear. However the trans may be in limp mode due to the speed sensor code (limp mode means the trans starts out in second gear in order to at least get to a mechanic). The first thing I would do is have these codes cleared as there may be absolutely nothing wrong with the transmission (especially if you pull the trans dip stick and the fluid does not have a burnt smell. The vehicle should drive normally after that. If the check engine light comes back, have the codes scanned ASAP (before any other unrelated code sets). Chances are it may be the output speed sensor if this happens (easy fix). Hope this helps

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.

Input speed sensor

The input shaft speed sensor is located on the side of the transmission by where the engine "inputs" power to the transmission (via torque converter), thus rotating the input shaft.
The output speed sensor is located by where the axles attach to the transmission, and measures the speed that the transmission "outputs" to the axles (which make the wheels turn) and that data is also used for your speedometer reading.

My 91 dodge stealth is in limp mode how do i fix this transmission problem

Your car is in "limp"mode because the computer doesn't know what speed your doing,So it doesn't shift,
There are three possible reasons for this,
#1= input sensor faulty on transmission,
#2=output sensor faulty on transmission,
#3=speed sensor faulty on transmission,
you need to have the transmission codes read to know which one,Autozone checks codes for free.

Intrepid won't shift out of first gear, codes 0700, 0740, 0605

Your car most likely has gone into what is commonly called "limp in mode" The codes are transmission codes and you'll need to have it checked out and repaired. Something very common to Intrepids are the vehicle speed sensors going bad. If one or both go bad it will go into limp in mode and not shift properly. There is an input and an output speed sensor on these transmissions. Normally we would just change both because they are relatively inexpensive and easy to change. Hope that helps, gl.
