SOURCE: transmission 2003 saturn vue 4cyh cvt trans

If you are below 100 psi then you have a major leak inside the transmission. These will read upwards of 700 psi and require a special gauge to check line pressure. As far as fixing this there are limited parts available for this transmission and a replacement unit is big bucks. Take the car to your saturn dealer and see what they will do. These have a 5 year 75,000 miles warranty for the transmission, and most of them are covering up to and past 100,000 miles for customer satisfaction. If you dont know much or anything about this transmission do not attempt to repair it. Let the trained professional tech at saturn take care of this.

I have a Nissan Serena 2003 model with CVT gearbox. It wount engage 1,2 when moving in low speed, or uphill.when behaving this way, its fails to reverse,or reverse in difficulty.


Have the codes read at Autozone. Check out the wiring to the speed sensor on the output shaft of the gearbox. Be prepared to change the speed sensor itself. Is the speedo functioning? Often when the speed sensor is faulty the speedo dial fails

Hey Todd I have a 2005 5.7 dodge magnum and it won't change gears as i speed up while driving also speedometer stopped working


EASY ONE.... Your VSS (Vehicle SPEED SENSOR) stopped working and it is this Sensor that gives the PCM/ECM the information to change gears. Once you change your VSS, and get it working, the Transmission will start working again...

I am Assuming that the Transmission stopped working at the same time the Speedometer did? Is that right?

If it is, then this is a easy fix. 1 bolt and one Wire Connector and DONE....

Holden suburban column auto...car won't go into reverse and takes a while to change to 2nd gear...is it major


It might be.
You should first change the gearbox oil and replace the gearbox oil filter, then retry.
If you are still having an issue, then check the vehicle's speed sensor and TCM.

Vehicle Speed Sensor


Cvt transmission is continuously variable transmission. VSS is vehicle speed sensor. A faulty sensor can make the transmission run erratic.

It won't change gears and speedometer is jerky


I had the same problem with my 2002 Grand Caravan. It turned out to be a broken wire attached to the speed sensor on the transmission housing. Try that first!
