5A-34 Automatic Transmission/Transaxle:
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 pressure check hole in transmission 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.
Automatic transmission line pressure
5) If check result is OK,disconnect special tool, then tighten fluid pressure check hole bolt to specified torque.
Tightening torque
Fluid pressure check hole bolt: 8 N·m (0.8 kgf-m, 6.0 lb-ft)
