Every truck owner knows the importance of a robust, reliable transmission. One of the most frequent complaints among RAM truck owners regards erratic shifting in Aisin transmissions. This shifting challenge can lead to sub-optimal fuel consumption and put unnecessary stress on the engine. In severe instances, it may cause the truck to fall out of gear while driving, posing a safety risk. Another common issue is a significant delay in transmission engagement, leading to a lag between the time a driver shifts the gear and when the transmission reacts. This issue is particularly noticeable when shifting from park to drive or reverse. This sluggish response can be frustrating for the driver and, over time, could potentially lead to more serious transmission problems. Overheating is another notable problem with RAM Aisin transmissions. This issue tends to crop up during heavy towing or when the vehicle is under intense stress.
