Print

Refer to Engine Removal & Installation in the Engine Mechanical Section.

CVT: Re0f09b



Specific to:

Nissan Altima 2009-2010

  1. Remove the engine and transaxle as an assembly.
    NOTE
    Using paint, put matching marks on the drive plate and torque converter when removing the torque converter to drive plate nuts.

  2.  
  3. Disconnect the electrical connectors from the following:

    CVT unit harness connector.
     
    Secondary speed sensor
     

  4.  
  5. Remove the harness from the transaxle.
  6.  
  7. Remove the transaxle to engine and engine to transaxle bolts.
  8.  
  9. Remove the CVT fluid charging pipe.
  10.  
  11. Separate the transaxle from the engine.
  12.  
  13. If necessary, remove the following from the CVT:

    Fluid cooler tube
     
    Air breather hose
     
    Brackets
     

  14.  

To install:

  1. Installation is in the reverse order of removal.
    CAUTION



    When replacing an engine or transaxle you must make sure any dowels are installed correctly during re-assembly.
     
    Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive train components.
     
    Do not reuse O-rings.
     
    When turning crankshaft, turn it clockwise as viewed from the front of the engine.
     
    When tightening the nuts for the torque converter while securing the crankshaft pulley bolt, be sure to confirm the tightening torque of the crankshaft pulley bolt.
     
    After converter is installed to drive plate, rotate crankshaft several turns to check that CVT rotates freely without binding.
     
    When installing the CVT to the engine, align the matching mark on the drive plate with the matching mark on the torque converter.
     

  2.  
  3. When installing CVT assembly to the engine assembly, attach the bolts in accordance with the following standard:

  5. Torque bolts 1, 2 and 3 to 55 ft. lbs. (75 Nm). Tighten bolts 4 to 32 ft. lbs. (43 Nm).
  6.  
  7. When installing the drive plate to torque converter nuts, tighten them temporarily. then tighten the nuts to the specified torque.
  8.  
  9. After completing installation, check for fluid leakage, fluid level, and the positions of CVT.
  10.  
  11. When replacing the CVT assembly, erase EEP ROM in TCM.
