Shift Schedules
As mentioned earlier, 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 -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 -12° F and below 36° F | - Delayed 2-3 upshift (approximately 22-31 mph) |
| . | ||
| - Delayed 3-4 upshift (45-53 mph) | ||
| - Early 4-3 costdown shift (approximately 30 mph) | ||
| - Early 3-2 coastdown shift (approximately 17 mph) | ||
| - High speed 4-2, 3-2, 2-1 kickdown shifts are prevented | ||
| - No EMCC | ||
| Warm | Oil temperature at start-up above 36° F and below 80 degree F | - Normal operation (upshift, kickdowns, and coastdowns) |
| . | ||
| - No EMCC | ||
| Hot | Oil temperature at start-up above 80° F | - Normal operation (upshift, kickdowns, and coastdowns) |
| . | ||
| - Full EMCC, no PEMCC except to engage FEMCC (except at closed throttle at speeds above 70-83 mph) | ||
| Overheat | Oil temperature above 240° F or engine coolant temperature above 244° F | - Delayed 2-3 upshift (25-32 mph) |
| - Delayed 3-4 upshift (41-48 mph) | ||
| - 3rd gear FEMCC from 30-48 mph | ||
| - 3rd gear PEMCC from 27-31 mph | ||
| Super Overheat | Oil temperature above 260° F | - All "Overheat" shift schedule features apply |
| - 2nd gear PEMCC above 22 mph | ||
| - Above 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 |
