Answer
Hello again,
Do not remove the transmission oil pan.Transmission has 2 speed sensors and they come as a kit, so you have to replace them both (I know you have only Pulse generator B code which is output sensor). One (the input sensor a.k.a. Pulse generator-A) is located on the back side of the transmission, acceassable from top. You will see it underneath the brake master cylinder.Only one bolt holding it and 2 wires coming out and going to the connector which is located underneath the battery tray.Other one (Output speed sensor a.k.a. Pulse Generator-B) located on the rear cover of the transmission. You can only reach that from the bottom. Just remove the front and side plastic covers, it will be on the rear transmission cover just above the oil pan. they both look exactly the same. Only wire lenghts are different and they both connected to the same connector. So while installing, make sure you installed them to the correct locations. Sensor with longer wire is input speed sensor and goes from the top.
