2004 Volvo C70 ProblemsConvertible Tops May Have Problems With Micro-Switches/Potentiometers
The convertible top may have problems with the micro-switches and potentiometers that help control the raising and lowering of the top.
Front upper strut mounts may wear prematurely, resulting in loud noise from the front of the vehicle when going over bumps.
Several complaints have been reported regarding Volvo C70 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 fix this issue so if available, the software should be updated before any repairs are made.
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
