The lurch you experienced was, I'm sure, due to the Borg-Warner and related
slush-boxes that were the only available autos in the old days.

And often badly adjusted.

The basic B-W of the 60s had a bowden cable between the throttle and box
which controlled when it changed gear. It also controlled the kick down
function. Get some wear in the throttle mechanism, and you lost kickdown.
Rather than fix/adjust the throttle linkage, most simply adjusted the
gearbox cable. Until it kicked down again. Messing up the relationship.
Ending up with incorrect gear change speeds, rough changes, and a bad
thump engaging drive, etc. And then blamed the gearbox. ;-)
