Shift speed doesn't matter. The gears aren't what slips. The torque converter acts like a clutch. If you've ever been in a vehicle with a shift kit, you'll understand. No slip = very hard shift.

ZF 8 spd

All sequential upshifts and downshifts with this design involve just releasing one shift element and engaging another. In engineering literature, this is referred to as a “clutch to clutch” shift. Many skip shifts are also possible in the same way, e.g. a shift from Eighth to Fourth involves releasing brake A and engaging brake B while leaving clutches D and E engaged. This transmission therefore shifts very quickly. If the torque converter is replaced by a launch clutch, this transmission would be equivalent to a dual clutch transmission.

Yeah...so?

So this.

Shifts are clutch to clutch, the torque converter isn't involved.

Exactly. I just tried to explain it, probably to long winded. Clutches in an auto are what is used to get between the gears. Programing and line pressure is what determines what type of shift and overlap. In other words firmness and time.
