91, Stall speed, transmission input
The ratio of transmission input speed to engine speed is monitored

Diagnosis conditions
- ATF level OK
- ATF temperature [>] 60° C
- Selector lever position 'D', 2nd, 3rd, 4th or 5th gear
- Gear engagement completed
- Output shaft speed [<] 641 rpm

Possible fault cause
- ATF level too low or too high
- Short circuit to ground/B+/mutual short circuit or open circuit in the circuit to the control module
- Faulty shielding of signal lines
- Sensor for transmission input speed (turbine sensor) is faulty
- Torque converter clutch is slipping
- Torque converter is faulty
- Tiptronic control module is faulty

Affected pins
Pin 16, pin 44 and pin 23

Diagnosis/troubleshooting

WARNING:
- Danger of scalding by hot ATF.
- Hot ATF can cause burns if it comes into contact with the skin or clothing.
- Drain ATF only when cold.
- Wear suitable protective clothing.

DANGER:
Risk of damage to the transmission input speed sensor (turbine sensor) if the hydraulic control unit is laid on its back when removed.
- When the hydraulic control unit is removed, place it only with its bottom side on a suitable surface.
