Overheating and the transmission switching directly to neutral from a forward gear are two common problems with Dodge transmissions.The former only affects automatic Dodge transmissions.
Dodge transmissions are prone to flat-filter cracking, resulting in the transmission jumping to neutral from a forward gear. Incorrect seating may also cause the problem. These incidents result in the transmission to sucking air in at random intervals and losing oil pressure. Low oil pressure then causes the transmission to function as if in neutral.
When the driver forces the vehicle to perform heavy tasks, such as towing over the limit suggested by the manufacturer, the transmission overheats. Installing an aftermarket cooler helps in such cases. The transmission should never reach 200 degrees Fahrenheit.
