Aisin AS69RC transmission problems

In this brief guide, we are going to provide you with the common Aisin AS69RC transmission problems and what are the solutions to these problems.

Aisin AS69RC Transmissions are made by Aisin AW and they are the largest producer of automatic transmissions in the world. Aisin AW supplies to 55 automotive companies, from Ford and Nissan to MINI and Volvo. However, there are many problems with Aisin AS69RC transmissions and we’ll tell you how you can solve them.

What are the common problems with Aisin AS69RC transmissions?

Most of the common problems with Aisin AS69RC transmission are:

  • Lack of throttle response
  • Leaking Transmission Fluid
  • Burning Smell
  • Torque Converter Issues
  • Gears Slipping

Why is lack of throttle response a problem with Aisin AS69RC transmissions?

You would want a seamless and smooth shift even at low throttle input, so if your Aisin AS69RC transmission is shifting slow or responding slow even at high throttle then there is definitely a problem.

What signs are shown by this Aisin AS69RC transmission problem?

You would immediately notice and sense if the automatic transmission is shifting slowly from one gear to another as this is one of most important issues with automatic transmissions

What is the solution to this Aisin AS69RC transmission problem?

Firstly try replacing the transmission pressure sensor, if that doesn’t work then check for an oil leak in the servo assembly of the particular gear. These are primarily two fixes for this problem.

Why is leaking transmission fluid a problem with Aisin AS69RC transmissions?

Aisin AS69RC Transmissions are leakage proof systems and if anything is leaking out of them then it is definitely a sign of a problem which may cause serious trouble for you in the future. 

What signs are shown by this Aisin AS69RC transmission problem?

You would get an error such as P0842 or errors in the similar range which are associated with transmission fluid pressure. If these sensors get a low pressure this will indicate there is not enough fluid and a leakage somewhere in the transmission.  

What is the solution to this Aisin AS69RC transmission problem?

Finding where the leak is and closing it, is the most obvious solution to fix this sign before it causes mechanical damage to your car. Usually the gaskets or the seals in the transmission are worn out or broken to cause a fluid leak.

Why is the burning smell a problem with Aisin AS69RC transmissions?

If you get a burning odor, your transmission fluid is probably overheating due to clutch debris, breakdown of metallic components and sludge. Therefore this sign is a cause for concern.

What signs are shown by this Aisin AS69RC transmission problem?

The smell itself should be a good sign that there is something wrong with your automatic transmission. However you will get a more detailed sign if you use a software diagnostic tool.

What is the solution to this Aisin AS69RC transmission problem?

Check the transmission oil and its level. If it is too low then fill the required amount of oil in the transmission. If it is too dirty, then drain the entire oil from the transmission and fill it again. Also check for any debris and discarded materials. 

Why is torque converter Issues a problem with Aisin AS69RC transmissions?

If your torque converter or if you are not getting the desired response when you release the brake and press the throttle pedal then you are most definitely experiencing torque converter problems.

What signs are shown by this Aisin AS69RC transmission problem?

There will be specific error codes shown from the diagnostic tool if the torque converter stator has been broken or completely failed. 

What is the solution to this Aisin AS69RC transmission problem?

If the clutch of the torque converter is worn out then you need to replace it or else the stator might be broken which also might need replacing. In the worst case the entire assembly needs to be replaced if the state of the torque converter is beyond repair.

Why is gears slipping a problem with Aisin AS69RC transmissions?

Aisin AS69RC Transmission gear systems are not designed to slip and if you are experiencing slippage then it is definitely a sign of a problem with the mechanical components of the transmission.

What signs are shown by this Aisin AS69RC transmission problem?

Usually you would get an error in the range to P0780s or further if you are experiencing this sign of a transmission malfunction. Also if the shift solenoid is broken or malfunctioning then you would get an error code P0745 or above.

What is the solution to this Aisin AS69RC transmission problem?

Replacing the solenoids would work and you would not get the sign but if there is a problem with the mechanical component then it is better if you would visit a mechanic or service station. 

How to diagnose these common problems with Aisin AS69RC transmission precisely?

If you need to precisely diagnose these common problems then you need to use a diagnostic tool which is software based and can be connected to the vehicle electronic system as Aisin AS69RC is fully electronically controlled heavy duty transmission. 

How to prevent getting these problems in the first place?

To prevent these problems you need to change the Aisin transmission oil as per the manual or when it is too dirty. This is the easiest and most effective way to take care of your vehicle transmission and also drive your vehicle in a recommended way.

FAQs: Aisin AS69RC transmission problems

What’s better: Aisin or 68RFE?

The 68RFE is not as robust as the Aisin in any way, shape, or form. These are two completely different transmissions. The difference is that Aisin has a much deeper First gear ratio (3.75:1) and Second gear ratio (2.0:1) to maximize the 6.7L’s torque delivery for more low-end pulling power.

How much horsepower can the Aisin transmission handle?

The Aisin 6-speed automatic is one of the transmissions and it can handle up to 400 hp and 1,000 lb-ft of clean-diesel torque. With the Aisin transmission, it can tow 31,000 pounds.
