Can a bad input-turbine speed sensor make your can not shift into all the gears on 2000 vw jetta with 1.8l turbogas?

Yes, a bad input-turbine speed sensor can cause your car not to shift into all the gears on a 2000 VW Jetta with a 1.8L turbogas engine. The input-turbine speed sensor is responsible for sending signals to the transmission control module (TCM) about the speed of the input shaft of the transmission. This information is used by the TCM to determine when to shift gears. If the input-turbine speed sensor is not working properly, the TCM will not be able to receive the correct information, which can cause the transmission to shift erratically or not shift into all the gears.

Here are some symptoms that can indicate a bad input-turbine speed sensor:

- The transmission does not shift into all the gears

- The transmission shifts erratically

- The engine revs too high before shifting gears

- The car hesitates or bucks when shifting gears

- The check engine light is on

If you are experiencing any of these symptoms, it is important to have your vehicle inspected by a qualified mechanic to determine if the input-turbine speed sensor is the cause. If the sensor is found to be faulty, it will need to be replaced in order to restore proper shifting operation to the transmission.
