Dodge 2008 Charger Automobile User Manual


 
Torque Converter Clutch
A feature designed to improve fuel economy has been
added to the automatic transmission of this vehicle. A
clutch within the torque converter engages automatically
at calibrated speeds. This may result in a slightly differ-
ent feeling or response during normal operation in high
gear. When the vehicle speed drops, or during accelera-
tion, the clutch automatically and smoothly disengages.
NOTE:
The torque converter clutch will not engage until the
transmission fluid and engine coolant is warm (usu-
ally after 1–3 miles [1.6–4.8 km] of driving). Because
engine speed is higher when the torque converter
clutch is not engaged, it may seem as if the transmis-
sion is not shifting into “Overdrive” when cold. This is
considered a normal condition. Pulling the selector
lever into the “3” position will show that the transmis-
sion is able to shift into and out of “Overdrive.”
If the vehicle has not been driven for several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
transmission fluid partially draining from the torque
converter into the transmission. This is considered a
normal condition and it will not cause damage to the
transmission. The torque converter will refill within 5
seconds of shifting from “P” (Park) into any other gear
position.
Transmission Limp Home Mode
The transmission is monitored for abnormal conditions.
If a condition is detected that could cause damage, the
transmission automatically shifts into second gear. The
transmission remains in second gear despite the forward
gear selected. “P” (Park), “R” (Reverse), and “N” (Neu-
tral) will continue to operate. This Reset feature allows
the vehicle to be driven to a dealer for service without
damaging the transmission.
