XC70 transmission problems

In this brief guide, we are going to provide you with the common XC70 transmission problems and what you can do to rectify these problems before they worsen.

Nowadays, XC70 Transmission does not require any manual input to shift gears while driving as most of their cars have automatic transmission. Various sensors and mechatronic systems work in coordination to shift gears automatically. 

However, there are many problems with automatic transmissions and we’ll tell you how you can solve them.

XC70 Transmissions are automatic transmissions and have a global reputation for quality, reliability and durability but there are some common problems with XC70 transmission.

What are the common problems with XC70 transmission?

Most of the common problems with XC70 transmission problems are:

  • Shift Solenoid failure
  • Incorrect gear ratio
  • Torque converter malfunction
  • Mechatronic malfunction
  • Transmission slippage

Why is Shift Solenoid failure a problem with  XC70 transmission?

Shift solenoid malfunction means there is a problem with the gear shifting. A XC70 transmission changes gear by directing pressurized transmission fluid to move clutches and bands around. The computer controls all of this with little spring-loaded devices called solenoids.

What are the signs of this problem with the XC70 transmission?

P0750 is the code that will be shown if there is a shift solenoid malfunction with the XC70 transmissions. This is a generic code which you will get using OBD-II for your transmission.

How to solve this XC70 transmission problem?

Some common solutions are changing the transmission fluid and filter or replacing faulty solenoids. Also you can repair or replace a faulty transmission pump.

Why is Incorrect gear ratio a problem with XC70 transmission?

If the XC70 transmission is with an incorrect gear ratio then it can cause anything from shift solenoid problems to transmission fluid problems.

What are the signs of this problem with the  XC70 transmission?

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.

How to solve this  XC70 transmission problem?

Wires connecting sensors to the transmission control module and other electrical connections should be inspected and any damaged or corroded wires in and near the transmission control module should be repaired or replaced to fix this issue.

Why is Torque converter malfunction a problem with  XC70  transmission?

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 engagement or disengagement problems.

What are the signs of this problem with the  XC70 transmission?

Firstly you would be unable to stop the car when releasing the throttle pedal for disengagement problem and secondly for engagement from even if you press too much throttle the car will not move forward.

How to solve this XC70 transmission problem?

If the clutch of the torque converter is worn out then you need to replace it or else the solenoid 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 Mechatronic malfunction a problem with XC70  transmission?

Automatic transmissions are very advanced but dependent on a lot of mechatronic components. If these mechatronic components fail then automatic transmission is unable to function properly and results in poor drive.

What are the signs of this problem with the  XC70 transmission?

Error codes appear when the mechatronic sensors fail and in the majority of cases when the cable connecting the sensor to the transmission control unit has come loose.

How to solve this  XC70 transmission problem?

Make sure that the cable is properly connected to the sensor or the sensor itself is working. These are the ways of fixing this malfunction on a XC70.

Why is Transmission slippage a problem with  XC70 transmission?

The XC70 transmission system is not designed to slip and if you are experiencing slippage then it could cause slow response or further damage to the transmission system. So, it is definitely a sign of a problem with the mechanical components of the transmission.

What are the signs of this problem with the  XC70 transmission?

You will be able to hear the gear slip while driving and this would be a good sign if there is slipping. Also, an error code will be displayed if you use a diagnostic tool.

How to solve this  XC70 transmission problem?

The solenoids of the two gears might be worn out and need to be replaced. Also, there is a chance that these solenoids might also be broken. Rarely, complete mechanical failure occurs with these transmissions.

How to diagnose these common problems with XC70  transmission?

To properly diagnose these problems, you need a scan tool to read these codes from the Transmission Control Unit. Firstly, If a XC70 transmission is malfunctioning, it immediately informs the driver with an error message on the screen.

How to prevent getting these problems in the first place?

Regularly changing your gearbox oil and other lubricants may save you a lot of trouble and money in the future. Although many experts suggest different number miles for servicing, your car manual will give you a proper recommendation when you should change. The best way to prevent these problems is to avoid buying these cars in the first place as these cars are known to have  transmission problems. 

FAQs: XC70 transmission problems

What goes wrong with Volvo XC70?

Owners of 2001 XC70s experience transmission failure at around 149,000 miles, while owners of 2003 model years experience the same problem at an ever-lower average of 108,000 miles. Both the second and top-worst-rated problems are with the XC70’s transmission, existing mostly in 2001 and 2003 model years. 

Is the Volvo XC70 expensive to maintain?

Overall the Volvo XC70 has yearly car maintenance costs totaling $804. Given that the Volvo XC70 has an average of $804 and that the average vehicle costs $651 annually, the XC70 is substantially cheaper to maintain.
