Disadvantages of the Mazda G4A-EL gearbox

  • Since the gearbox is installed with powerful motors, all its problems are associated with wear.
  • The torque converter clutch is the first to give out, clogging the lubricant and solenoids of the automatic transmission.
  • The wear on the bushings will make itself known through progressive transmission vibrations.
  • Overdrive and Reverse clutch drums are also often replaced.
  • Consumables here include the brake band and torque converter oil seal.
