Transmission problem
1990 Plymouth Laser 4 cyl Front Wheel Drive Automatic

i was told my input and output speed sensors (pulse generators) were bad on my 1990 plymouth laser transmission 4g37I4. Where are these located? Is there a diagram anywhere I can use to find them? Is this the vss or just speed sensor everywehere I go they say they are two seperate things.

my car wont shift out of 1 or 2nd gear I can go about 25 miles an hour.

Hello and thanks for the donation!

Your vehicle speed sensors are located on top of the transaxle and they are different than a regular speed sensor.

You will probably have to order it from the dealer unless you can find some at a local salvage yard. I believe it is a dealer only item.
