• 6RA40特性

  ·同軸行星輪系變速器

  ·液力變矩器帶打滑控制的鎖止離合器

  ·配有內置TCU的液壓控制單元

  ·自我診斷功能

  ·換擋響應時間短

  ·整體設計有效提高燃油經濟性

• 6RA40 FEATURES

  ·6-automatic forward gears

  ·1 selectable reverse gear

  ·Coaxial planetary transmission

  ·Hydrodynamic converter with controlled converter lock-up clutch(GWK)

  ·Hydraulic control unit with integral electronic transmission control(EGS/TCU)

  ·Electronic-hydraulic shift point position and gear shift control

  ·Mechanical gearshift option with 7 optional selector lever positons

  ·Short response time shifting

  ·Self-dianosis

  ·Fuel economy

• 控制器主要控制功能

  ·自動變速

  ·T變速器自我保護：低檔互鎖、超速檔互鎖、倒檔互鎖

  ·錯誤換擋（例如：發動機轉速4000rpm，從N-D,N-R）市，ECU可根據變速器的請求降低扭矩

  ·缺省/緊急模式
  當ECU失效時（斷電），下列檔位將被使用
  1-3檔失效時，接合第三檔
  4-6檔失效時，接合第五檔；
  重新啟動時接合第三檔

  ·Can通訊功能

• MAJOR TRANSMISSION CONTROL

  ·Transmission Function

  ·Transmission self-protection function:Downshift interlock,over speed interlock and reverse Gear interlock

  ·Misuse shifts(e.g.changing form N-D,N-R,at engine speed 4000 rpm) are conteracted by the engine controller which reduces the engine torque on transmission

  ·Default/emergency mode
  If the ECU fails(no power), the following forward gears will be engaged.
  Failure in 1st-3re gear Emergency gear:3rd
  Failure 4th-6th gear Emergency gear:5th
  3rd gear is engaged following a restart.
