Trans brake is activated on manual programs (3 to 8 by default) after pressing the brake and holding the up gear on the selector or paddles.

1. Select M mode.
2. Select a program from P3-P8.
3. Depress the foot brake.
4. Pull the gear selector towards you and hold it.
5. Release the foot brake and continue to hold the gear selector.
6.full gas.
7. Release the gear selector.
8. Enjoy

Thank you! What does it mean "select M mode" Is it something BMW related only?
Do I have to be in manual mode? (pull the gear selecto toward?)?

Manual mode. Gear selector to the left.

Do I have to be in manual mode?

yes. T-brake working only in manual mode, but program P3 (fox example) will shift gears automatically at high revs.

Thank you! working perfectly. Extremally useful when you start in the mood.

How "bad" is this mode for the transmission when it comes to long term reliability?

You have to watch the oil temperature. It's easy to overheat the oil.
On T-brakes, the driveshafts fail the most, I have not noticed other problems.

Is it possible to make "pre-tensions" on driveshafts when use T-brake?
(for reduce impact.)

It is possible to connect the "stop brake" valves through the relay and actuate from unused AUX in TCU
