1. Park the automobile on a flat and even floor.
2. Shift the gear successively to each position, inject ATF into the torque converter and oil circuit
and then place the gear lever on N.
3. Clean all filth around the dip stick and take it out to confirm the ATF oil level.
Note: if ATF smells burned and appears black, there must be something wrong with the gearbox,
in which case, the idle speed test shall not be carried out.
4. Check if ATF oil level is at the HOT mark. If the level is lower than the mark, please fill in
more ATF until the level reaches the HOT mark.

Oil pressure test
Note:
The wheels will turn during oil pressure test. Touch or collide with the turning wheels will result
the
re test will display many

in unnecessary personal injury. Please watch out during test.
The oil pressure gauge is fixed onto various parts of the gearbox so that the pressure value of
hydraulic circuit at each gear position can be measured. The oil pressu
