  10. Give bolts/nut of fastening of a back support of transmission to a cross-section beam. Slightly raise transmission with a transfer case, then give bolts of fastening of a beam to a car frame. Remove a cross-section beam.
  1. For a transmission detachment from a cross-section beam give a big central bolt (shooter).
  1. Slightly raise transmission and a transfer case (if it is equipped), then give three bolts (arrow) of fastening of the left side of a cross-section beam to a frame.

… give two bolts (arrow) of fastening of the right side of a cross-section beam to a frame and remove a beam.

  1. On all-wheel drive models remove a transfer case (Head the Transfer case).

If you do not plan to make transmission replacement, and remove it only for ensuring access to other components, such as the rotation converter, real need for removal of a transfer case is absent. However, it is necessary to notice that transmission removal assembled with a transfer case is much more difficult procedure, than their removal separately.


If you decided to leave a transfer case attached to transmission, take care of existence of safety chains for block fastening on a jack head. Transmission falling / a transfer case from a jack is fraught with the most serious consequences, up to an exit of components out of operation and receiving personal mutilations.

  1. Remove from transmission a cover of access to the rotation converter. On some models for its fastening three bolts, on others - three are used.
  2. Remove a starter (Head System of electric equipment of the engine).
  3. Mark position of the converter of rotation in relation to a driving disk for a guarantee of their correct installation at assembly (use white paint or a marker).
  1. Mark position of the converter of rotation in relation to a driving disk for the purpose of their correct installation at assembly - this factor makes essential impact on observance of balancing of the engine!
  1. Give bolts of fastening of the converter to a driving disk. For ensuring access to each of them turn a cranked shaft (only clockwise at the sight of in front).
  1. For ensuring access to each of bolts of fastening of the converter of rotation to a driving disk in the course of their otdavaniye turn a cranked shaft clockwise (at a view of the engine in front).
  1. Hang out the engine by means of a telezhechny jack or the winch (Head Ryadny the six-cylinder engine).
  2. Give the bottom bolts of fastening of transmission to the engine.
  3. Slightly omit transmission (and, on 4WD models, a transfer case if it was not disconnected) and give the top bolts of fastening of transmission to the engine.
  4. Disunite the electric socket and remove the sensor of provision of a cranked shaft (The head of System of decrease in toxicity of the fulfilled gases and engine management).

If to leave the sensor on the engine block, at removal (installation) of transmission it is easy for damaging.
