Common problems with Dodge transmissions include hard and erratic shifting, overheating, moving into neutral from a forward gear, delay in acceleration, and failure of the Check Engine light. Other problems include fluctuations in revolutions per minute at higher speeds, transmission slippage and downward shifting.
A defective solenoid can lead to the failure of a transmission to shift correctly or it might fail totally in some selected gears. A faulty transmission cooler, use of incorrect transmission fluid or an overfilled transmission fluid can cause high temperatures during transmission. A broken filter or a worn-out O-ring can cause the transmission to jump into neutral from a forward gear.
Outdated automatic transmission software on the car computer or a worn-out spark plug can result in delayed acceleration when a Dodge engine is starting. A faulty oxygen sensor, a loosely fitted gas cap or a worn-out catalytic converter can cause the Check Engine light to turn on while driving without warning the driver.
A low fluid level, a burnt transmission fluid, a broken transmission band or a transmission fluid leakage can cause transmission slippage in and out of overdrive. Additionally, a locked-up torque converter can cause fluctuations in revolutions per minute while driving at higher speeds. An electrical fault, a broken speed sensor or a failure of the transmission range sensor can cause unexpected downward shifting in a Dodge engine.
