Every truck owner knows the importance of a robust, reliable transmission. It’s the heart of the vehicle, enabling smooth power transition and optimal driving performance.
One renowned transmission system in the world of heavy-duty trucks is the Aisin transmission, which you’ll find in several RAM models. However, like any other automotive component, it has faced a fair share of issues that we’ll delve into in this article.
We’ll explore the common problems with RAM Aisin transmission, providing an understanding of each issue in detail.
Common RAM Aisin transmission Issues
- Erratic Shifts and Unpredictable Gear Behavior
One of the most frequent complaints among RAM truck owners regards erratic shifting in Aisin transmissions.
Some users report that the vehicle struggles to shift gears, particularly between 3rd and 4th.
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.

- Delayed Engagement
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.
- Transmission Overheating
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.
Overheating can cause significant transmission damage if not addressed immediately. It could lead to warped components or, worse, a complete transmission failure.
- Frequent Transmission Fluid Leaks
Fluid leaks are a recurring complaint in RAM trucks with Aisin transmissions. The transmission fluid plays a crucial role in lubricating the system and helping it run smoothly. Leaks can lead to low fluid levels, potentially causing shifting problems and eventual transmission wear and tear.
- Transmission Slipping
One of the concerning issues reported by some RAM Aisin transmission users is transmission slipping. This situation arises when the transmission unexpectedly “slips” into a lower or higher gear without any driver input.
It tends to occur while shifting gears or during acceleration, leading to an unanticipated change in speed and RPM. This is not just frustrating for the driver but can also lead to hazardous driving conditions.

- Difficulty in Shifting into Overdrive
For RAM trucks that regularly tow heavy loads, overdrive is a crucial function. It allows the vehicle to maintain a lower RPM while driving at highway speeds, improving fuel efficiency.
Some Aisin transmission owners have reported difficulty getting the transmission to shift into overdrive. This issue often leads to a significant drop in fuel economy and can also put additional stress on the engine.
- Transmission Refusing to Go into Gear
A severe problem, though less common, is the transmission outright refusing to go into gear. Whether it’s failing to shift from park to drive or a specific gear being unselectable, this issue could lead to being stranded or severe mechanical damage.
When this happens, it’s often indicative of an internal failure and should be addressed immediately to avoid further damage to the transmission.
- Noise and Vibration Issues
Some RAM Aisin transmission owners report experiencing abnormal noise or vibrations when the vehicle is in motion. This problem typically occurs during acceleration or when shifting gears.
Noise and vibrations can point towards mechanical issues that need prompt attention.

Frequently Asked Questions (FAQ)
Now that we’ve explored the common RAM Aisin transmission problems let’s address some of the frequently asked questions related to this topic.
While Aisin transmissions are generally reliable, they’re not immune to issues. Common problems include erratic shifts, delayed engagement, overheating, transmission fluid leaks, and noise and vibration issues.
The debate between Aisin and Allison is subjective, and the preference depends on individual needs and experiences. Both are reliable and perform well in heavy-duty situations. However, some users have reported fewer issues with Allison transmissions compared to Aisin.
The 2023 RAM models equipped with Aisin transmissions have seen complaints similar to their predecessors, such as erratic shifting, delayed engagement, and transmission overheating. There have also been some reports of transmission fluid leaks.
The Dodge Ram 3500, which often uses the Aisin transmission, shares similar issues with other RAM models. Erratic shifts, delayed engagement, and overheating are the commonly reported problems. Additionally, some owners have noted excessive noise and vibrations during gear shifts.
Final Words
Despite these problems, it’s crucial to remember that the Aisin transmission in RAM trucks is generally well-regarded for its performance in heavy-duty applications. Like any mechanical system, it’s not perfect and will face issues over time.
Regular maintenance, staying alert to the signs of trouble, and prompt repairs can go a long way in mitigating these problems and extending the transmission’s lifespan. If you are a RAM truck owner with an Aisin transmission, it’s beneficial to be aware of these potential issues so you can act swiftly if they arise.
