The 2021 Ram trucks equipped with the Aisin transmission are known for their exceptional performance and reliability. However, like any mechanical system, the Aisin transmission may experience certain issues that can impact the driving experience. Let’s explore some common problems that owners of 2021 Ram trucks with Aisin transmissions might encounter.
1: Premature forward clutch failure
One of the common problems with the 2021 Ram Aisin transmission is premature forward clutch failure. This can manifest as slipping gears, difficulty in shifting, or loss of power while driving. If you notice any of these symptoms, it is crucial to have your transmission inspected by a qualified technician who can diagnose the issue and recommend the necessary repairs.
2: Engine RPM increase or partial engine stall when coming to a stop
Another issue that some owners may encounter is an increase in engine RPM or partial engine stall when coming to a stop. This can be frustrating and potentially dangerous, especially in traffic situations. It is essential to address this problem promptly to prevent any further damage to the transmission or engine components.
3: Engine stalling in Reverse and/or Drive
Some owners have reported instances of engine stalling when shifting into Reverse or Drive. This can be a significant inconvenience and may require immediate attention. A professional inspection is recommended to determine the root cause of the problem and perform the necessary repairs or adjustments.
4: Sudden shift to neutral after takeoff
One of the common problems reported with the 2021 Ram Aisin transmission is a sudden shift to neutral after takeoff. This can be a jarring experience for drivers and may leave them stranded in traffic. If you experience this issue, it is essential to have your transmission inspected by a qualified technician to determine the cause and necessary repairs.
5: The High-Pressure Oil Pump
Another potential problem with the Aisin transmission is related to the high-pressure oil pump. Some owners have reported issues with the pump failing, leading to a loss of hydraulic pressure. This can result in erratic shifting, slipping gears, or a complete loss of power. Prompt diagnosis and repair are crucial to prevent further damage to the transmission.
6: The Internal Wiring Harness
The internal wiring harness is another component that may present problems in the 2021 Ram Aisin transmission. Issues with the wiring harness can cause electrical malfunctions, leading to various transmission issues such as shifting problems or failure to engage gears correctly.
