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 and Matt Allen of Virginia Auto Service in Phoenix, AZ talk 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.
