What are the causes of Mazda 5 transmission failure?
1 Answers
Mazda 5 transmission failure reasons are as follows: 1. Engine idle speed is too high, causing delayed upshifting. 2. Improper adjustment of throttle cable or throttle position sensor, resulting in excessive main oil circuit pressure. 3. Faulty main oil circuit pressure regulator valve, causing excessive main oil circuit pressure. 4. Damper accumulator piston stuck, unable to provide damping effect. 5. Missing one-way valve steel ball, causing shift components to engage too quickly. 6. Slipping shift components, oil pressure solenoid valve not working. 7. Faulty electronic control unit (TCU). Symptoms of Mazda 5 transmission failure include: severe vibration when shifting from Park or Neutral to Reverse or Drive during startup; noticeable jerking during automatic transmission upshifts while driving.
