Shift Schedules

WARNING: This page is about a different car, the 2004 Dodge Intrepid, 2004 Chrysler Intrepid, 2004 Chrysler Concorde, and 2004 Chrysler 300M. 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.

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 Aboye 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
