TRANSAXLE ASSEMBLY
    

 1. Install a new pump to case O ring on the pump

         assembly and secure with petroleum jelly (See
         Figure 189).
     2. Install the stator shaft caged needle bearing into
         the pump housing and lubricate with transmission
         fluid (Figure 189).
     3. Attach the parking pawl assembly to the case and
         tighten the three bolts to 30 N m (22 Ft. lbs).
     4. Install the park lever actuator rod. The end with
         the two tangs fit into the lever.
     5. Install the input shaft, output shaft and differential.
         Grasp the input shaft and output shaft and mesh
         the gears. Have an assistant mesh the differential
         ring gear to the output shaft. Lower all three
         components at the same time. Apply petroleum
         jelly on the output shaft bearing to aid in the
         installation (See Figure 190).
         NOTICE: Input shaft, output shaft and 
         differential must be installed at the same time
         or damage may occur to the output shaft roller
         bearing inner race. Bearing failure will result.
    

 6. Install a new linkage seal and lubricate with

         petroleum jelly (See Figure 191).
     7. Install the input and output shaft case bearings into
         the case. Using a suitable pair of snap ring pliers,
         expand the snap ring and slide the bearing into the
         bearing bores. Snap ring grooves on the bearing
         should be UP on the output shaft bearing and
         DOWN on the input shaft bearing (See Figure
         192).
     8. Install a new O ring onto one end of the reverse
         idler gear shaft. Lube and install the reverse idler
         gear bearing and install a new O ring onto the
         opposite end of the shaft (See Figure 193).

     9. Install the reverse idler gear with the chamfer
         side of the gear towards the rear of the case
         (See Figure 193).   
   10. Lube the O rings and install the shaft through the
         rear of the case. Use a twisting motion and make
         sure the O rings stay in position (See Figure 193).  
   11. Install the reverse idler shaft cap using a twisting
         motion and torque the two bolts to 15 Foot lbs.
         (See Figure 193).
         IMPORTANT: If the transaxle was built in 
         early 1991 production year, the reverse idler
         gear shaft will not be equipped with O rings. If
         the transaxle is being overhauled, the shaft and
         idler gear should be updated.

   

12. Install case to rear cover dowel pins if necessary.

   13. Clean case and housing surfaces and apply sealant
         Loctite   515 or equivalent. Apply to both sides of 
         the gasket or case halves using a small roller (See 
         Figure 194).
   14. Lower the case over the shafts and work down 
         onto the differential bearing. It may be necessary 
         to turn the reverse idler gear to index the gears 
         allowing the case to drop down into place (See 
         Figure 194).
   15. Install the case to converter housing bolts. Torque
         the bolts to the following specifications and in the
         numerical sequence shown in Figure 195.
         A) Short Bolts.....25 N m (18 ft. lbs.)
         B) Long Bolts.....28 N m (21 ft. lbs.)
         IMPORTANT: The two bolts on the torque 
         converter side of the housing should not be
         installed at this time.

   16. To check the differential end play, remove the 
         selective snap ring from the differential bearing 
         bore as shown in Figure 196.
   17. With a feeler gauge, measure the clearance from
         the bearing to the top of the snap ring groove (See
         Figure 197).
   18. The snap ring to be used should measure the same
          in thickness as to the amount of clearance that was
          measured in step 17. The ball bearings on the
          differential should have 0 clearance with no
          preload when the snap ring is installed. Below is
          the list of the different selective snap rings with
          their sizes and part numbers.

   19. Apply sealant Loctite  515 or equivalent to area of
         axle seal and install new axle seals (See Figure
         198).
   20. Install a new forward/reverse servo piston sealing
         ring as shown in Figure 199.
         A) Place servo piston on the seal installer base
              (SA9137T-2)
         B) Install the seal expander cone (SA9137T-1) to 
              the servo piston.
         C) Lube sealing ring and position on expander
              cone.
         D) Use the seal pusher (SA9143T) to install the 
              sealing ring.
