The rear corners are supported by jack stands to facilitate free movement of the wheels, the front tires are resting on wooden blocks. If it makes you feel better set the front corners on jack stands as well you will see at idle those tires don't move.

As a practical matter with engine idling while moving through the gears, there is little to no stress at all on the front axle. its idling at a stand still.

Lastly we're changing the transmission fluid not the differential fluid in this exercise. Even if I went through the gears with brakes on at idle its not going to hurt anything.

Whoever said this dangerous advice ought to check yourself before you call out a seasoned 40 yr plus experience backyard mechanic calling my procedure dangerous... you are an idiot and should stay out of big boy conversations about car repair and maintenance... you idiot! For the car I have and for just about any automatic transmission this procedure will work just fine for changing the trans fluid.

All of my work is carefully thought out and researched and well practiced before I would dare to give others advice.

I said it is dangerous because it is.

It could harm the person(s) involved and damage the vehicle. Allowing wheels to spin while on jack stands is not an uncommon practice even though the risk of the vehicle shifting/falling is worth noting. What you recommend takes the risk factor to a whole new level.

Also, you state the transmission needs to be level when in fact every piece of "official" literature I have seen says the vehicle/chassis should be level.

Why name calling? It doesn't contribute to the discussion in a positive way at all. Can you instead back up your claims with solid evidence to support the procedures you recommend?

Thanks in advance!

EDIT: pre XDrive models probably won't sustain differential damage by only allowing 1 axle to spin freely. I do not know as I have XDrive and haven't looked into the ins & outs of the previous design lots of others have. So, I could be mistaken.... Which happens from time to time.
