ME-SFI transmission shift delay, function - GF07.61-P-4023V
ENGINES 273.961 in MODEL 216, 221 with TRANSMISSION 722.9 up to Model Year 08 /Modification Year 07
Shown on Engine 272.963 in Model 171
The transmission shift delay warms up the catalytic converter more rapidly to its operating temperature after engine start.
The transmission shift delay is fully electronic. No additional components are required.
The engine control unit requests from the transmission control unit via the CAN data bus to alter the shift characteristic curves. The speed signal is provided via the CAN data bus.
The partial load shifts from 1st and 2nd gear into 3rd gear take place at higher engine speeds. Starting takes place in 1st gear only when drive program C is selected.
The transmission shift delay is active for max. 60 s under the following conditions:
- Coolant temperature at start less than 35°C
- Speed less than 40 km/h
