Hi to all.
I am new here and i am from israel so sorry about the spelling mistake.
My problem is strange - After i drive with the car at least 40 minute/10-20 KM and come to a red traffic light and i need to slow down, at low speed my car start to vibration, the same like if you stop the car with manualy transmission at first gear integrated.
If i am not put the transmission handle to N the engine is turn off.
I can restart the engine at P or N and everything is O.K .
The second i shift to R or D/2/1 the engine is turn off.
If i wait half an hour everything is o.k until the next half hour afterward.
My garage mechanic person said that i need a new transmission and he do not know what is the problem.
i look at few forums in israel and few guys got the same problem without a solution.
Some guys said to me to disconnect the Torque sensor that come from the radiator side.

Can you help me?

regards,

ALON

It sounds like the torque converter isn't disengaging. I don't think the trans needs replaced but rather a sensor or the converter.
