On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ and Matt Allen of Virginia Auto Service in Phoenix, AZ talk about everything to do with your transmission. Special on-site broadcast from Tri-City Transmission Open House event with special guests Keith Clark and Ken, mechanics from Tri-City Transmission. Also on this show:

• The worst case scenario is getting a new transmission when you don't need one.
• 1997 Pontiac Grand Prix: I changed the pan gasket and then my check engine code came up on the diagnostic for a TCC solenoid. There aren't any shift problems but I don't know what's going on.
• 2002 Buick Rendezvous: The all wheel drive light came on and my dealership is quoting me $600 to fix check valve in the rear end. Does the check valve cause this problem?
• Should I buy and have all of the tires changed at once on my all wheel drive or can I just put one on at a time?
• Is okay to have my transmission rebuilt?
• 2003 Ford Taurus: There's a coolant leak and there's no white smoke in the tailpipe so it might be heating it up in the cylinder somewhere.
• 2005 Lincoln Town Car: In stop and go traffic, my car is shifting really hard. Is this a transmission problem?
• Are all transmission fluids the same?
• 2006 Scion XB 100,000 miles: In the mornings, my car shifts very hard and I can feel a hard thump when I'm trying to get it up to speed.
• 2006 PT Cruiser 80,000 miles: When you accelerate the car, the transmission is making a whining noise and then quiets down around 40mph.

Cars talked about on this show are the 1997 Pontiac Grand Prix, 2002 Buick Rendezvous, 2003 Ford Taurus, 2005 Lincoln Town Car, 2006 Scion XB, 2006 PT Cruiser.
