ATF checked

Very beginning stage of cold starting in the morning, the starting attitude is strange, stumbling and hesitating phenomena in second and third gear also the neutral control shows stumbling a little.

This phenomena continues very beginning stage from the initial condition and after a while the strange attitude disappears according to the heat up of ATF, the volume increases by thermal volume expansion.

As I supposed the quire reaction of Aishin 4 speed trans-axle with neutral control system design disappeared just after applying additional ATF to 1,2L more. Newly added D2 Castle TOYOTA genuine ATF fairly obtained the originally natural gear shifting in a sophisticated manners.

The lack of ATF amount caused unpredictable trouble, the criminal of this affair was simply myself that mistook the way to measure and to ascertain the level gauge marking in motor rotating and warm condition. The layman like myself continues studying much in every basic experience.

As for NCP10 TOYOTA Vitz, ATF volume was just a bit less but within the tolerance with no problem would happen in future and on BC7 SUBARU Legacy LSi US model the level gauge showed much enough, may be too much?

The reason why the gear shifting by JATCO automatic 4 speed trans-axle isn't always so smooth as desired especially on the phase of shifting from second gear to third one.
The reconfirm on the ATF amount in BC7 Legacy must be performed again by reducing volume by extracting from a drain plug on the oil pan.
