Facing AMT issues in my 2019 Tata Tiago: The cause & repair costs

The mechanics started to take apart the piece under the gear lever and the part behind the air conditioner.

After dreading about AMT Issues in TATA cars, it has occurred to us.

We own a 2019 January purchased TATA Tiago XZA.

We have not encountered any major issues in the last 4.9 years of ownership, except for one-time oil Sensor replacement.

On November 27 Monday, we had some personal errands to run. We had a run for about 30 km and we reached the hospital for a checkup. After 2 hours from the hospital, we started the car, once the car passed the gate, the AMT fault warning light came in and we parked the car towards the roadside. We waited for 10 minutes with the engine off and started the car again. The warning light still popped up and the Neutral sign (N) was blinking. On moving the gear lever to A(drive), the car was not engaging to drive. The same was was for Reverse and for manual mode as well.

We contacted our local TATA ASC (Focuz Kozhencherry) and asked for our sales advisor. We advised it may be due to a sensor issue and arranged a pick-up. We insisted on a flatbed truck. Meanwhile, I sent my family back to the house and waited near the car. After about 1.5 Hours, the crane service truck reached and we transported the car to the service center.

A job card was opened and since it was almost past 5 pm they said they would start the next day. The mechanics started to take apart the piece under the gear lever and the part behind the air conditioner. They were checking for any loose wires that must have resulted in the error.

The next day around noon the service advisor called us and informed us that on checking the error codes, there were two errors one with TCU and the other with the gear lever. They took apart the gearbox and informed us they would confirm the next day.

Today they informed us that the fault is with the TCU part and needs to be replaced. The total cost of the TCU part is Rs 28096 excluding the labour charges. It has to be ordered and the part should arrive from Pune.

The car has been in the Service center for a week now.
