Is there still engine torque absorption from the transmission while in neutral?
So what does that test actually proof?
Does this show the "load" the convertor creates on the engine?
Where as this "load" with a high stall convertor should be very low, right?
And i guess that is what might drag the engine down, causing a low vacuum?
As when trowing it in Drive the load increases more and the vacuum drops more...well together with the idle.
