Known Problems

There are several common complaints regarding Volvo V70 transmission shifting issues. Long shift times between gear shifts, hard shifting, hard downshifting and a loss of transmission operation to name a few.

If the issue is minor, a transmission software update may address this. If available, the software should be updated before any repairs are made. After a software update or repair, the shift adaptation needs to be reset. A good quality Volvo repair shop will know how to perform this task.

There are several technical service bulletins (TSB's) available from Volvo that address these shifting issues and they should be consulted by the repair shop during the automatic transmission diagnostic process.

Regular servicing of the transmission fluid can help with preventing transmission failure, but not in all cases. Follow the suggested fluid replacement interval recommended by Volvo. You will find this in your owners manual, or find it here>>

A well-documented and well-known issue with the Volvo V70 built between 2005-2010 is harsh shifting from the 6-speed automatic transmission, and slight slippage between gears. This has been noted as hesitation to accelerate, especially from a stop.

Mainly, software issues have been to blame for these mishaps, but mechanical malfunctions related to shift solenoids and the valve body have also been major causes. Finally, the automatic transmissions in these models are sold as ‘sealed for life’, yet the transmission fluid does not seem to last the complete service life of the vehicle.

Correction of these issues often requires a simple software update, meaning the vehicle only needs to be plugged in, and the transmission controller receives new programming meant to fix these drivability concerns. In cases where this does not correct concerns, the transmission must be removed, inspected, and repaired, possibly requiring a complete rebuild.

To mitigate these issues from escalating to a full transmission rebuild, many technicians recommend replacing the transmission fluid at regular intervals, yet the manufacturer has never offered this guidance. 

 

The front control arm bushings wear out, resulting in alignment issues and squeaking and/or knocking noises from the front end. Worn bushings will require replacement.

The anti-lock brake system (ABS) warning light and/or other dash warning lights may illuminate due to a failed ABS Control Module. Replacement of the failed module is generally required to correct this concern.

The MAF sensor is prone to failure and will turn on the Check Engine Light when it fails.

The anti-lock brake system (ABS) Control Unit has a high failure rate. When this fault occurs, the ABS light will illuminate and codes may be stored indicating a problem with the ABS Pump Motor, or Wheel Speed Sensors, but the problem is the ABS Control Module.

Other symptoms may include an illuminated Check Engine and transmission shift light, and the speedometer may stop working as well.

Note: The brake system will operate normally however during a panic stop the Anti Lock Brakes will not work and the wheels may lock-up, causing a lack of vehicle control under these situations.

The turbocharger return pipe seal may develop an oil leak. The leak can begin very small, but will eventually progress into a large leak. Our technicians recommend having this repaired at first signs of leakage.

Front and/or rear sway bar end links may wear out prematurely, causing a knocking noise from the front or rear of the vehicle when driving on bumpy roads. Our technicians recommend inspecting the links at each service, they should be replaced if any looseness is found.

The upper engine mount may wear prematurely. Symptoms may include a harsh feeling when the transmission is shifting and roughness when the engine is idling. Worn engine mounts should be replaced as necessary.

Engine oil leaks from the PCV housing are common.
