F4A41 F4A42 F4A51 Input Output Speed Sensor Set 1996 and up

I bought three sets and had to return all of them. The output speed sensor does not fit any of my three 2002 Elantras, without lightly sanding down the plastic lip. The 'O' rings supplied on them are slightly too fat and get mashed during install. One of the output speed sensors was totally dead. The input speed sensors work, but are not very good. They caused the engine to over rev before shifting. I observed the output of the input speed sensor using the torque app, with the Hyundai add on, and they show the sensors are not consistent in their output.

I put these 2 sensors in and my Transmission works fine. This, after a shop told me my trans was shot and I needed a new one for $1,700.00

The output speed sensor does not fit any of my 2001 Elantra, has a slightly bigger plastic lip. The 'O' rings supplied on them are slightly too big and get mashed during install.

I observed the output of the input speed sensor using the OBD torque app and they show the sensors are not consistent in their output.

Good

worked great

exellent

the output sensor is not for that car and thats the one i need it most

The product doesn't fit the f4a42 A/T directly. You have to modify the o-ring landing and the o-ring retaining plastic portion(dremel or sandpaper) its only maybe .3 millimeters too big. Other than that, it seems to be working.
