Shift Schedules
WARNING: This page is about a different car, the 2010 Dodge Avenger and 2010 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
The PCM has programming that allows it to select a variety of shift schedules. Shift schedule selection is dependent on the following:
- Shift lever position
- Throttle position
- Engine load
- Fluid temperature
- Software level
As driving conditions change, the PCM appropriately adjusts the shift schedule. Refer to the following chart to determine the appropriate operation expected, depending on driving conditions.
| Schedule | Condition | Expected Operation |
|---|---|---|
| Extreme Cold | Oil temperature at start-up below -27° C (16° F) | Park, Reverse, Neutral and 2nd gear only (prevents shifting which may fail a clutch with frequent shifts) |
| - | ||
| Cold | Oil temperature at start-up above -24° C (-12° F) and below 2° C (36° F) | - Delayed 2-3 upshift (approximately 35-50 kmh (22-31 mph) |
| - | ||
| - Delayed 3-4 upshift 72.5-85 kmh (45-53 mph) | ||
| - Early 4-3 coastdown shift (approximately 30 mph) | ||
| - Early 3-2 coastdown shift (approximately 27 kmh (17 mph)) | ||
| - High speed 4-2, 3-2, 2-1 kickdown shifts are prevented | ||
| - No EMCC | ||
| Warm | Oil temperature at start-up above 2° C (36° F) and below 27° C (80° F) | - Normal operation (upshift, kickdowns, and coastdowns) |
| - | ||
| - No EMCC | ||
| Hot | Oil temperature at start-up above 27° C (80° F) | - Normal operation (upshift, kickdowns, and coastdowns) |
| - | ||
| - Full EMCC, no PEMCC except to engage FEMCC (except at closed throttle at speeds above 112.5-133.5 kmh (70-83 mph)) | ||
| Overheat | Oil temperature above 115° C (240° F) or engine coolant temperature above 118° C (244° F) | - Delayed 2-3 upshift 40-51.5 kmh (25-32 mph) |
| - Delayed 3-4 upshift 66-77 kmh (41-48 mph) | ||
| - 3rd gear FEMCC from 48-77 kmh (30-48 mph) | ||
| - 3rd gear PEMCC from 43.5-50 kmh (27-31 mph) | ||
| Super Overheat | Oil temperature above 127° C (260° F) | - All "Overheat" shift schedule features apply |
| - 2nd gear PEMCC above 35 kmh (22 mph) | ||
| - Above 35 kmh (22 mph) the torque converter will not unlock unless the throttle is closed or if a wide open throttle 2nd PEMCC to 1 kickdown is made |
