  26.  
  27. Place a support under the engine with a wooden block between the support and the engine.
  28.  


CAUTION
The wooden block and support should be no more than about 25mm away from the engine so that when the engine is lowered, damage will not occur to any underhood components.

  1. Remove the transmission mount-to-crossmember bolts.
  2.  
  3. Raise the transmission SLIGHTLY, just enough to take the weight of the transmission off of the crossmember. Remove the crossmember-to-frame mounting bolts and remove the crossmember from the vehicle.
  4.  
  5. Slowly lower the transmission until the engine rests on the support placed during Step 14.
  6.  
  7. Disconnect the two fluid cooler lines at the transmission. Plug the lines and the holes in the transmission to prevent the entry of dirt.
  8.  

Before performing Step 19, place a drain pan under the torque convertor area of the transmission. Fluid leakage will occur as the transmission is uncoupled.

  1. Remove the transmission-to-engine mounting bolts. Carefully pull the transmission to the rear and after the transmission uncouples from the engine, lower the transmission out of the vehicle.
  2.  
  3. Remove the torque convertor from the flywheel.
  4.  

Prior to installation of the transmission, Toyota recommends to check the torque convertor and flywheel run-out dimensions. If either of these run-out limits are beyond the maximum allowable limits, excessive wear of the front transmission seal will occur.
