Frequently Asked Questions

Is it safe to drive with this transmission code?

Use caution. Transmission codes can indicate serious issues that worsen with continued driving. Avoid highway speeds until diagnosed.

How much does a transmission repair cost?

Solenoid replacement: $200-500. Valve body: $500-1,000. Full rebuild: $1,800-3,500. Get a proper diagnosis first.
