Troubleshooting
Line Pressure TestS7RS0B5104016
Purpose of this test is to check operat ing conditions of each part by measuring fluid pressure in fluid pressure line.
Line pressure test requires the following conditions.
• Automatic fluid is at normal operating temperature (70 – 80 °C / 158 – 176 °F).
• Fluid is replenished to proper level (between FULL and LOW on dipstick).
• Air conditioner switch is turned OFF.
1) Apply parking brake securely and place chocks against wheels.
2) Remove fluid pressure check hole plug bolt.
3) Attach oil pressure gauge to fluid pr essure check hole in transaxle case.
Special tool
(A): 09925-37811-001
CAUTION!
After attaching oil pressure gauge, check that no fluid leakage exists.

4) Depress foot brake fully, run engine at idle and stall then check fluid pressure in “D” or “R” range.
CAUTION!
• Do not continue running engine at stall speed longer than 5 seconds.
• After performing line pressure test, be sure to leave engine running at idle for longer than one minute before performing another line pressure test.

One-way clutch No.1 assembly1) Install one-way clutch No.1 assembly (2) to rear planetary sun gear subassembly (1).
2) Securing rear planetary sun gear subassembly, ensure that one-way clutch No.1 assembly rotates
only in one direction.
If the one-way clutch rotates in both directions or it
does not rotate in either direction, replace it with new
one.
Adjustment
Differential side bearing preload 1) After applying A/T fluid to differential assembly, fit it to transaxle case.
2) Install torque converter housing to transaxle case, then tighten bolts (1) to specified torque.
Tightening torque
Torque converter housing bolt (a): 29 N·m (2.9
kgf-m, 21 lb-ft) 3) Measure bearing preload (a) by using a special tool.
Special tool
(A): 09928–06050
Differential side bearing preload (a) measured as
starting torque
In the case of new bearing: 0.78 – 1.37 N ⋅m (7.9 –
13.9 kg-cm, 0.58 – 1.01 lb-ft)
In the case of reused bearing: 0.39 – 0.69 N ⋅m
(3.9 – 6.9 kg-cm, 0.29 – 0.51 lb-ft)
4) If bearing preload is out of specification, select shim with suitable thickness from among the list below
and replace it. Then adjust differential side bearing
preload within specification.
Available shim thickness
NOTE
Record measured differential side bearing,
because it is necessary to adjust
countershaft bearing preload.
