Please can you kindly provide me with the exact location of the transmission module and the wiring for a diagram containing ground signal.

Any information that can be helpful to solve this problem. Hi Ken, please I noticed I would just need the diagram and signals of this solenoid valve connector.

Hi Andrin,

Here is the location for the transmission control module and the wiring diagrams for it, but I can tell you I have seen a weak input shaft sensor cause this problem as well. Here is the location for the sensor as well. Clear the codes once the sensor or TCM is replaced. Check out the images (below). Please let us know what happens.

Thank you, Ken, I have read the updates and the diagrams. May I have measurements for testing the out speed sensor and input sensors? Also, if possible, to have the pinout of for the solenoid valve connector Pinout signals?

This is what they say:

For most Hyundai models, the resistance of both sensors should be within the range of 500 to 1,000 ohms.

This sounds too high to me btw. Which solenoid valve are you talking about?

Transmission Output speed sensor and the input speed sensor, which is behind the valve body inside the gearbox.

Also if I can get the pin out for the fuse box connector, and the power and ground for the TCM/ECM. For the ohms resistance, I will also double check. Thank you.
