P0715 Input/Turbine Speed Sensor Circuit Malfunction
Hello. I am having problem with my car, which is e320 1998. I've looked at every thread about this problem, and still have a few questions. Here is my situation.
My transmission started acting funny, started switching funny, then it would stuck in 2nd gear and wouldn't switch to anything else. I would stop the car, turn it on again - everything works fine, then after sometime - same thing, 2nd only. It acted like this for couple days, then CEL came on and car would stay in 2nd and R gears permanently, which is Limp Home mode. So i ordered a new TCU, put it in and car worked for 2 minutes fine, gears would switch fine, but only for 2 minutes, then i stopped the car, turn it on again - it works fine, for 2 minutes, then it stopped working again permanenetly until now. I also took off minus wire off the battery, to clear the CEL light. So i noticed that CEL comes on when i press gas and it goes up to 4000 rmp, only then it comes on.
So my questions are, why did new TCU worked for only 2 minutes?
And what would be the problem with my car, a conductor plate?
Please help me.
