replace the input speed sensor to transmission and the wiring pigtail all are available at your chrysler dealer take your vehicle registration in to the parts counter so they have your vin # to get the right part and it is the front of trans by fluid linres to radiator.

SOURCE: transmission input speed sensor location

It is located on the front of the transmission. you will see 2 of them one on the left under small transmission lines it is the input then to the right behind the radiator overflow there is the other one. Easiest way to change them is with a 1" deep well socket

Only code p0734 2001 caravan

Hi there:
This code means that the transmission is slipping in high gear and the TCM (TRansmission Control Mocule) logic thinks it has incorrect ratio since it monitors input and output speed. Keep in mind that TCM uses input from the input speed sensor and output speed sensor to determine gear ratios. The TCM then compares the known gear ratio to the calculated gear ratio for the current range.


Check HERE test procedure.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.


Thank you for using FixYa, have a nice day.

97 Dodge Caravan Sport Once it warms up it stays in second gear until i put it on nutural- shut vehicle off- and then restart it and it will shift fine. What could it be?

The transmission is going into failsafe mode, meaning the computer is seeing an electrical problem and turning off all solenoids locking it into on gear. Best bet is to get a scan tool and read the codes in the transmission module, common problems are the input and output speed sensors. If you are having problems with the speedometer, you probably need an output speed sensor. I've also had problems with pressure switch codes that have lead to replacing the valve body. If you have a speed sensor code i recommend replacing both the input and output speed sensors, they screw into the front side of the transmission.

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.

2000 dodge grand caravan sport, the check engine light is on, but no codes found after checking with reader, speedometer is jumping all over the place, from 0 to 120 mph, when the speedometer jumps around,...

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.
