Hello,

The car overheated today and all coolant went out right on top of transmission case a few minutes later after cooled down the gear stuck in fifth gear and the only code I read is engine input speed sensor range malfunction. Changed the input speed sensor but transmission still on the same gear any help is highly appreciated.

thanks in advance

BTW: the car is 2007 Samsung SM7 which is not on your list. But it shares the same engine, transmission.

Hello,

This car has the CVT transmission which had problems with. I would service the unit with the specific fluid called for the CVT unit. Here is a guide to walk you through the steps. Now if it is too late the fluid change wont help but it is worth a try. If the transmission is slipping this code will remain.

Please run down this guide and report back.

FYI, the transmission was fine and all sensors and harnesses, wires and connectors as well.
The reason of this issue was the cam position sensor bank 2 (this car has 2 sensors ).
Once I replaced it transmission back to normal and drive with no issue.

No other code were detected, but it says code was emitted by injection.
I scanned the engine unit found that one of cam shaft sensors not reading engine speed. I just replaced it as normal engine issue didn't expect it to be the reason to get transmission in limp in mode.
