2007 Chevrolet Tahoe P0573 Brake Switch High Voltage Code - Transmission Slipping Issue

Model: Tahoe Fault Code: P0573 Posted: 2023-04-12 17:31

I'm experiencing a P0573 brake switch high voltage fault code on my 2007 Chevrolet Tahoe. The vehicle exhibits a loss of transmission power, which feels like the transmission is slipping. I noticed a service traction control warning light that has since disappeared, and currently only the P0573 code remains. Transmission fluid level is normal and not burnt. No other diagnostic codes or warning lights are present. I'm seeking advice from experienced owners or mechanics—any insights into potential causes or fixes would be greatly appreciated. Thank you for your help.
