Sensor diagnosis
Hello all, I was welding in my new floor pans and lets just say there was an accident and my car became a FIREbird but anyway it was put out but the 2 sensors on my transmission got burnt through it and nothing else I checked everything, I was wondering if someone could tell me what these 2 sensors are so I can replace them, sorry for the bad angle its a tight spot to get a camera in. if someone could tell me that would be great thankyou.

Im sorry but what does TCC and TV cable mean, im just trying to make sure I get the correct things for when I order the parts, I think I understand the TV cable but the one that looks like a sensor plug im not sure.

Re: Sensor diagnosis
Both of those:
-Throttle-Valve Cable
-Torque-Converter Clutch Circuit
Are very important in regard to the Life of the THM700-R4 Transmission.
The T.V. Cable must be connected and adjusted correctly, otherwise the the Transmission will not have the appropriate Line-Pressure...
And the Transmission will slip, Burn-Up, and Fail.
The Torque-Converter Lock-Up Circuit must be operational to keep the Transmission from Over-Heating while Expressway Driving.
