1999 Volvo S80 ProblemsFront Upper Strut Mounts May Fail and Cause Noise Over Bumps
Front upper strut mounts may wear prematurely, resulting in loud noise from the front of the vehicle when going over bumps.
Many complaints have been reported regarding Volvo S80 transmission shifting issues. Long shift times between gear shifts, hard shifting, hard downshifting and a loss of transmission operation all together to name a few.
If the issue is minor, a transmission software update may address this issue so 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: http://bit.ly/Volvo_Owners_Manuals
There have been reports of a failed ABS Control Module causing the ABS and Check Engine warning lights to illuminate. Repair or replacement of the failed module will be required to correct this issue.
