GM Engine and Transmission Diagnostic and Repair Advice

Engine and transmission problems aren't too common on most GM products, especially if you follow the scheduled maintenance guide recommendations. Flushing your vehicle's automatic transmission periodically (as required), changing your vehicle's engine oil and filter frequently, and keeping a close eye on air and fuel filters all adds up to consistent, reliable performance.

However, if you have an engine or transmission problem, we're here to help. If you have a question about engine or transmission replacement or parts, please don't hesitate to call us.

We've compiled some information to help you diagnose and/or fix problems with your vehicle's powertrain, and you can find an alphabetical list of the guides we've created below. If you have a specific question about the parts you need, or if you see an issue with our guides, please contact us or call 877-498-7278.
