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 the symptoms and problems you can't afford ignore with your vehicle. Special guest includes Joel Bartko of Arizona Import Specialists. Also on this show:

• Never ignore the temperature rising, the smell or squealing sounds you may notice in your car that could cause an overheating problem.
• If you notice a coolant leak, get your car checked out soon in order to hopefully avoid an overheating problem.
• If your car is overheating, turn off the engine right away. Do not try to drive it to the repair shop, have your car towed in order to avoid further damage.
• 2008 Toyota Corolla 80,000 miles: I was told I needed all four transmission mounts replaced and it was going to cost $1000. Does this price sound right?
• 2006 Dodge Caravan: When I turn my steering wheel it makes a humming sound right behind the wheel and I'm not sure what that is.
• Nissan Sentra 115,000 miles: The car runs great but I was told I should change out my spark plugs. If nothings wrong with the car, should I change them out anyway?
• 2005 Toyota Avalon 85,000 miles: Is an independant shop capable of doing a transmission repair or should I go to a speciatly shop?
• Should I used Toyota transmission fluid on my Toyota or can I use something else?
• 2004 Subaru Impreza 93,000 miles: When I make a left turn there's a clunking sound and then when I'm going straight on the freeway, I'm hearing a rubbing noise from the wheel.
• 1996 GMC Jimmy 125,000 miles: An error code for cylinder number 5 misfiring came up. We've had multiple repairs done on the truck and the code keeps coming up. What should we do?
• What is your opinion on the auto shops that advertise the $15 special?
• 2000 BMW 323: I'm hearing some metal to metal noises on the rear part of my car is this a problem with the rear differential bushing? 
• 1956 Chevy Bel Air: The front and rear seal is leaking on the transmission and I'm wondering if there's a local shop that would be willing to work on a classic car?
