  8. On models 4WD disconnect draft of switching of the transfer case from the lever of switching of the modes on a box (The head the Transfer case).
  9. Prop up transmission a jack - preferably use of a jack of special type. Safety chains of such jack will help to record reliably on it transmission.
  10. Give bolts/nut of fastening of a back support of transmission to a cross beam. Slightly raise transmission with the transfer case, then give bolts of fastening of a beam to a car frame. Remove a cross beam.
  1. For a transmission detachment from a cross beam give a big central bolt (shooter).
  1. Slightly raise transmission and the transfer case (if it is equipped), then give three bolts (arrow) of fastening of the left side of a cross beam to a frame.

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

  1. On all-wheel drive models remove the transfer case (The head the Transfer case).

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


If you decided to leave the transfer case attached to transmission, take care of existence of safety chains for fastening of the block on a jack head. Falling of transmission / the 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. Uncover with transmission of access to the rotation converter. On some models for its fastening three bolts, on others - three are used.
  2. Remove a starter (The head Sistema 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 has significant effect 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 bent shaft (only clockwise at the front view).
  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 bent shaft clockwise (at a view of the engine in front).
  1. Hang out the engine by means of a cart jack or the winch (The head the Line six-cylinder engine).
  2. Give the lower bolts of fastening of transmission to the engine.
  3. Slightly lower transmission (and, on models 4WD, the 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 bent shaft (The head Sistemy of decrease in toxicity of the fulfilled gases and engine management).

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

  1. Pick up the phone of the probe of measurement of level of transmission liquid (see the illustrations Scheme of Transfer of Rotation of Transmission (AW-4), the Scheme of transfer of rotation of transmission (42RE) or the Scheme of transfer of rotation of transmission (42RH/46RH)). Remove and throw out a sealing ring of a tube of the probe.
  2. Shift transmission back, removing it from the directing pins on the engine. Previously make sure that the converter of rotation is disconnected from a driving disk. Fix the converter in transmission in order to avoid its loss at removal of the last.
  3. Lower transmission and take it from under the car.

Installation

 PERFORMANCE ORDER

  1. Before installation make sure that the nave of the converter of rotation is reliably joined with the pump.
  2. Having fixed transmission (and on models 4WD and the transfer case if it is still attached to transmission) on a jack, lift it in adjusting situation. Try to hold transmission horizontally that it was not slipped out by the rotation converter. Connect lines of a cooler of transmission liquid.
  3. Turn the rotation converter, trying to obtain combination of adjusting tags on it and on a driving disk (item 6).
  4. Carefully advance transmission (with the transfer case if it is connected - on models 4WD) forward until there is a joining of guides of pins with the rotation converter.
  5. Insert bolts of fastening of a case of transmission to the engine. Be verified with data of illustrative material (see the illustrations Scheme of Transfer of Rotation of Transmission (AW-4), the Scheme of transfer of rotation of transmission (42RE) or the Scheme of transfer of rotation of transmission (42RH/46RH)). Tighten bolts with the required effort.
  6. Establish bolts of fastening of the converter of rotation to a driving disk. Tighten bolts with the required effort (see Specifications to this Chapter). Establish a cover of access to the converter, having strongly tightened its bolts.

If for fastening of the converter you use new bolts, compare their length (measured from the lower cut of a head until the end of a carving part) to the values given in Specifications. Application of bolts of excessive length is fraught with damage of surfaces of the converter.

  1. Establish bolts of fastening of a back support of transmission to a cross beam and bolts of fastening of a beam to a frame. Strongly tighten bolts.
  2. Remove the jacks holding transmission (with the transfer case if it is connected - on models 4WD).
