The latency for doing what? Shifting from reverse to drive? The ZF transmissions in BMWs are very fast shifting even though they are torque converters and there are paddle shifters on the wheel.
ZF 4HP22 in my older (4.0 litre) Range Rover, 4HP24 in my newer one with the 4.6 engine. Actually they're both the same age to within weeks, I just got the 4.6 eight years after the 4.0, but anyway - it takes about a quarter of a second to change up or down if you manually prod the gearstick coming up to some bends. It's definitely faster than the R380 manual gearboxes fitted to Discos, Defenders and manual P38s, which needs a fair bit of time in neutral to settle out before you select the next gear.
This is '80s technology, mind you, with a fairly simple computer grafted on to bring it up to the white heat of the mid-'90s.

The BMW ZF is much faster. They are even using it in their M cars.
