When to Call a Professional

Call a transmission specialist if fluid is burnt or contaminated, if multiple transmission codes are present, if the transmission slips or fails to engage gears, or if solenoid testing reveals internal electrical faults. Professional diagnosis is also recommended if you're uncomfortable working with automotive electrical systems or if the problem persists after basic troubleshooting.
