Stage 1 Program
The Stage 1 map adds gear display and removes the transmission’s torque limit, while enhancing fuel efficiency in Eco mode. It is suitable for all types of drivers.
TTS Transmission Stage 1:
1. Activated gear display in D mode.
2. Removed internal torque limitations of the transmission.
3. Optimized shift logic in D mode, making it smoother, more comfortable, and fuel-efficient.
Stage 2/Stage 2 Plus Program
The Stage 2/Stage 2 Plus map focuses more on sportiness without compromising comfort. The transmission’s adjusted shift points and clutch pressure enable faster shifts and reduce response times. It's suitable for all types of drivers, especially those looking for more driving pleasure in Sport/Sport+ modes.
TTS Transmission Stage 2:
1. Activated gear display in D mode.
2. Removed internal torque limitations of the transmission.
3. Optimized shift logic in D mode, making it smoother and more comfortable.
4. When DTC or DSC OFF is selected, the transmission uses fast shift mode.
5. Shift points and timing have been adjusted for faster overall shifts.
6. The map sets the transmission to Sport-Automatic (SA 2TB) mode, giving standard transmissions the same performance without added wear and tear.
TTS Transmission Stage 2 Plus:
7. Based on Stage 2, with even faster shifting during daily driving.
Stage 3/Stage 3 Plus Program
Stage 3/Stage 3 Plus retains most of the features from Stage 1 and 2 while providing even faster, more responsive shifting in all modes. It's ideal for drivers who seek driving pleasure across all modes and want to take BMW’s sporty characteristics to new heights.
TTS Transmission Stage 3:
1. Activated gear display in D mode.
2. Removed internal torque limitations of the transmission.
3. Optimized shift logic in D mode, making it smoother and more comfortable.
4. When DTC or DSC OFF is selected, the transmission uses fast shift mode.
5. Shift points and timing have been adjusted for faster overall shifts.
6. The map sets the transmission to Sport-Automatic (SA 2TB) mode, giving standard transmissions the same performance without added wear and tear.
7. Much faster and more responsive shifts in all modes.
8. True M shifting mode (in Sport or Sport+ M mode, the transmission will not upshift automatically).
TTS Transmission Stage 3 Plus:
9. Based on Stage 3, with faster shifts during daily driving.
10. Advanced True M shifting mode (no automatic upshifts in Comfort DSC On/DTC/DSC OFF, Sport DSC On, or Sport+ DTC modes).
Stage 4 Program
Stage 4 builds on all Stage 3 features, enhancing comfort for long-term driving in full-time sport mode. It is ideal for BMW drivers who love experiencing driving pleasure in sport mode for extended periods.
TTS Transmission Stage 4:
1. Activated gear display in D mode.
2. Removed internal torque limitations of the transmission.
3. Optimized shift logic in D mode, making it smoother and more comfortable.
4. When DTC or DSC OFF is selected, the transmission uses fast shift mode.
5. Shift points and timing have been adjusted for faster overall shifts.
6. The map sets the transmission to Sport-Automatic (SA 2TB) mode, giving standard transmissions the same performance without added wear and tear.
7. Much faster and more responsive shifts in all modes.
8. True M shifting mode (in Sport or Sport+ M mode, the transmission will not upshift automatically).
9. The fastest shifts in daily driving.
10. Cruise control Sport mode allows the use of 8th gear. The default Sport cruise mode does not use 8th gear, and the shift points are lowered.
11. Disabled kick-down forced downshift switch.
Stage 5/Stage 5 Plus/Race Mode for High Power Models Program
Stage 5/Stage 5 Plus builds on most of the Stage 4 features, adding racing and track-oriented transmission characteristics. It is ideal for BMW drivers seeking the ultimate racing experience. Unleash the Beast!
TTS Transmission Stage 5:
1. Activated gear display in D mode.
2. Removed internal torque limitations of the transmission.
3. Optimized shift logic in D mode, making it smoother and more comfortable.
4. When DTC or DSC OFF is selected, the transmission uses fast shift mode.
5. Shift points and timing have been adjusted for faster overall shifts.
6. The map sets the transmission to Sport-Automatic (SA 2TB) mode, giving standard transmissions the same performance without added wear and tear.
7. Much faster and more responsive shifts in all modes.
8. True M shifting mode (in Sport or Sport+ M mode, the transmission will not upshift automatically).
9. The fastest shifts in daily driving.
10. Cruise control Sport mode allows the use of 8th gear. The default Sport cruise mode does not use 8th gear, and the shift points are lowered.
11. Increased clutch pressure to prevent slippage, extend clutch life, and handle higher torque (strongly recommended for high-power, high-torque vehicles).
TTS Transmission Stage 5 Plus:
12. Based on Stage 5, the kick-down forced downshift switch is disabled.
