I have an h2, the person I bought it from said the sensor is set to economy and and you can change the settings with a certain remote in which he gave me. Is that the same thing as the electronic sensor ylu are referring to?

 

TPS i believe is what you are talking about Throttle Position Sensor with it set to economy
i was more along the lines of
A transmission solenoid that is what I was referencing to an electro-mechanical device that controls the flow of transmission fluid through the hydraulic circuits within the transmission. There are several sensors that work for the TCU transmission control unit. please correct me if i am wrong. Hopefully by adding the fluid you have fixed your problem.
