Bumper to Bumper Radio, the car guys on KTAR, 92.3 FM in Phoenix, AZ, broadcast every Saturday from 11:00 am to noon. On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ talks about transmission related car problems you may experience and how to correctly diagnose them. Also on this show:

• Why self-maintenance of your vehicle has become less common over the years.
• Transmission problems vs computer control problems.
• What causes your transmission to “slip” or “stutter” at certain speeds.
• When you should visit a transmission specialist rather than a general repair shop.
• 2013 Ford Focus: Around 10 mph, my truck starts to stutter. I was told this was an issue with the computer clutch. Any advice?
• 2009 Volvo C30: I’m considering buying this car. What can you tell me about Volvo’s reputation when it comes to transmissions?
• 2006 Infiniti M35: I’ve had my motor and transmission mounts checked, but am still sensing a problem. What else could be causing this vibration issue?
• When would you recommend having a transmission flushed?
• 2012 Volkswagen Jetta: My vehicle is involved in the diesel issues surrounding VW. Would you recommend selling it back or waiting for a solution to come up?
• 1990 Ford F250: My truck has issues shifting between 2nd and 3rd gear. Have you seen this before with a truck similar to mine?

Cars talked about on this show are the 2013 Ford Focus, 2009 Volvo C30, 2006 Infiniti M35, 2012 Volkswagen Jetta, and the 1990 Ford F250.
