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.

Troubleshooting
“P” Range TestS6RW0D5104016
1) Stop vehicle on a slope of 5 degrees or more, shift select lever to “P” range and at the same time apply parking
brake.
2) After stopping engine, depress brake pedal and release parking brake.
3) Then, release brake pedal gradually and check that vehicle remains stationary.
4) Depress brake pedal and shift select lever to “N” range.
5) Then, release brake pedal gradually and check that vehicle moves.
WARNING!
Before test, make sure no one is around vehicle or down on a slope and keep watchful for safety
during test.
