Automatic Transmission May Not Downshift Correctly
Drive Train, July 5, 2012
RepairPal Expert Overview
Our Quick Take:
The transmission may not downshift correctly (such as shifting from fifth to fourth when coasting) due to a computer software error. This could result in lower than expected engine RPMs and possible engine stall, increasing the risk of a crash.
What Should You Do?
Volvo will notify owners of affected vehicles beginning July 19, 2012. If you are experiencing stalling or transmission shifting issues, or you don't receive notification and you feel you should have, please contact your dealer. It’s helpful to have your vehicle identification number (VIN) handy when you call.
A computer software error may prevent the transmission from downshifting, such as shifting from fifth to fourth gear when coasting. This can result in decreased engine RPMs and possible engine stall, increasing the risk of a crash. Dealers will upgrade the software to the transmission control module to correct this concern. The Volvo recall number is 255.
