BUT...maybe those still under new car warranties could convince someone somewhere to put this in when their factory trans goes south.

Didn't I hear engine braking in each down shift? Wasn't aware stock 4L70 did that.
I've seen aftermarket one built to do it.

I like that vid. I thought it was funny how he gave you that extra sense of durability by slamming down each part after giving its nomenclature hahaha!
