2004 Chevrolet Corvette Z06 Problems

Service transmission every 30,000 miles
Our technicians highly recommend that the transmission is serviced every 30,000 miles to avoid problems and maintain optimal operating order. If the fluid is dark in color, the transmission should be flushed.
Check Engine Light Due to Restricted Secondary Air Injection Check Valves

One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.

Contamination of extended life coolant
Extended life coolant may become contaminated and require cooling system service before the recommended 100,000 miles.
