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 what you can do to avoid major repairs during the lifetime of your vehicle. Also on this show:

• Radiators, timing belts, and other parts you should replace to avoid a more expensive repair bill in the future.
• What mileage intervals you should keep in mind to expect major maintenance.
• How long you should expect your battery to last.
• 2007 Chevrolet Avalanche: My truck is jolting after accelerating from a stop. Do I need a transmission flush?
• 2009 Chevrolet 3500: After exiting the freeway, my van begins to shift hard. A shop has told me that I need a new transmission after a scan. Is that a reliable diagnosis?
• 2015 Kia Sol: After changing my oil, I’ve started to notice a leak. Is this just an issue with the filter?
• 2004 GMC Envoy: I moved to Phoenix recently and I’ve noticed my truck running hot. Is this normal? Or is there an issue with my cooling system?
• 2015 Kia Sol: In the morning, my car shifts hard from 1st to 2nd gear until it gets warmed up. Is this something to be concerned about?

Cars talked about on this show are the 2007 Chevrolet Avalanche, 2009 Chevrolet 3500, 2015 Kia Sol, and the 2004 GMC Envoy.
