1998 Buick Skylark P0758 and P0442: Troubleshooting Transmission and Evap System Issues
I recently purchased a 1998 Buick Skylark with 178,000 miles from a used car dealership. It was previously a rental vehicle and is otherwise in good running condition. However, within less than 24 hours of ownership, the Check Engine light activated. After taking it to Auto Zone, I received a P075
I don't have specific pricing quotes for these repairs, but it's important to note that your vehicle was purchased without warranty. The P0758 code indicates an electrical issue in the shift solenoid B circuit—this can cause the transmission to fail during downshifts, requiring manual shifting. The dealer reportedly fixed a 'short' in the circuit, but symptoms returned after a day. Since the check engine light didn't come back on, it's possible they simply removed the warning bulb from the dashboard. Additionally, the P0442 code points to an evaporation system leak. As a single parent with three children, I'm looking for realistic estimates on repair costs and where to find reliable service. Can anyone share experience or approximate prices for fixing both the transmission solenoid issue and the EVAP system? I live in Casper, WY.
