Update:

I've had a chance to check the tran.level at "cold",and "hot" levels over the last couple days.
In this model ,the accepted way is what ins the manual.[sm=exactly.gif]
I checked the level several times,after running hot,engine off,and the level is repeatable.

I assume the tran. level cold can be at any level in the sump, and be erroneous as i measured.

Thanks to all who answered
