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 effects the cold winter weather has on our cars. Special guest includes Joel Bartko of Arizona Import Specialists. Also on this show:

• What is TPMS?
• How does the cold air affect the tire pressure in my car?
• Is my radiator affected by cold weather?
• What are the things I should be checking with weather change?
• 1992 Geo Metro 1000 CC 3 cylinder 150,000 miles: The springs in the seats are worn down so the seat sits really low. The airbag is in the steering wheel so it's pointed directly in my face. Is this safe? Should I disable the air bag?
• 1994 Chevy 1500 307,000 miles: I had the transmission rebuilt at 140,000 miles. When I go about 65mph on the freeway, the tachometer is reading high. Is this a transmission problem?  
• 2008 Chevrolet Tahoe: My tire pressure sensor went out. Should I replace all four?
• 1972 F100 Pickup: I need to replace a transmission mount on my pickup and I'm wondering if I can do this on my own or if it's too difficult?
• 2006 Hyundai Sonata: Does my 4 cylinder car have a timing belt and when should I be looking to replacing this?
• 1993 Honda Accord 195,000 miles: When I sit in neutral, the rpm's start fluctuating.
