Hi Ken, I am sure you are referring to the speed sensor which is connected to the trans body.

Do i have to open the cover and empty the transmission fluid to get to it, or its just fitted on the outside of the gear box?

Hi Ken, i got the transmission cover removed. I can see two turbine sensors at both ends opposite to each other. How can i test the sensors to know which is malfunctioning? Can i also interchange them?

Hi Ken. I got both sensors out and i did a resistance test with a voltage meter. On one i got 3.50 oms and the second i got 3.33 oms. I also did live data on output speed i realize the sensor with the 3.33 omes does not transmit as that of 3.50, while i hook the sensors with my ignition key open i had another mechanic using a screwdriver to touch the metal part on the sensors.
