MPT in SUBARU AT

As I mentioned before, the toggle switch is prepared on dash surface on just upper position of Exhaust Temp Alarm lamp, so it is possible to exchange AWD to 2WD(FF) while driving. Blocking phenomena could be eliminated by switching, I founded it out. By doing this from the cabin the locked clutch plate could be unlocked probably because of the oil pressure drifting? Let's imagine that any scorching might happen in the worst case, the color of ATF have to be changed from clear pink to dirty blown, so periodical checking would notice me the defect at the clutch surfaces?
I decided to wait and see the phenomena for the time being. The test drive today as long as 120km on highway caused no color change in ATF. Further investigation would be done by checking ATF color change.
Automatic trans-axle, automatic driving system and well established wheel alignment and constructive geometry, driving on the highway  are the good requirement to invite Sandman on earth, the best care must be taken not to sleep while driving, because the situation of sleeping with eye opening surely happens!
