Ok, I pulled out my 200r tonight and am replacing it with a th350 tomorrow. On the 200r there is a sensor on the driver side of the transmission well actually on both trannies. The only difference is that the 200r has a four prong sensor and the th350 has a 2 prong. I was wondering what this sensor was for and if I am gonna need too hook up the connector to the senor on the th350? Any info is appreciated.
