• Engine running
• Coolant temperature at start <50 °C
• Vehicle speed < 53 km/h

Transmission shift delay, general points Transmission shift delay brings the firewall catalytic converter more quickly up to operating temperature after engine start.

The ME-SFI control unit (N3/10) controls the transmission shift delay according to the following sensor and signal:

• Coolant temperature sensor (B11/4)
• ESP control unit (N47-5), vehicle speed over the chassis CAN (CAN E)

Transmission shift delay function sequence 

Transmission shift delay is active for a maximum of 160 s and exclusively takes place electronically.

Over the drive train CAN (CAN C), the ME-SFI control unit tells the ETC control unit (N15/3) to adjust the shift characteristics.

Partial load gear shifts (1-2-1, 2-3-2) thus take place at higher engine speeds or at higher vehicle speeds.
