If you had a two speed, then it was a GM Powerglide, which IIRC came out
with the EH & beyond (red motor) until the advent of the dreaded Trimatic.
The Hydramatic was a three speed which GM claimed as a four speed, as they
regarded third gear convertor locked / unlocked as two gears.

Wrong.
May I sarcastically say: the EK was either stopped or it fkn
went slow (two speeds). Although I suppose stop isn't a speed. :-)
It took 23secs for the quarter and struggled to 100km/h in
25secs. It was a dog.
And just to add to the confusion, if you ever drove one, the
auto would only change *twice*. ;-)

The Roto Hydramatic:
In Australia the transmission was just called the Hydramatic.
The Roto Hydramatic was cheaper and smoother than the earlier
Hydramatic, but slower, softer shifts sacrificed performance
for refinement. American owners discovered that it was less
durable than the earlier Hydramatic, and was prone to various
mechanical problems. The factory caused confusion in
describing the 3 speed Hydra-Matic as a 4-S model or a 4 stage
transmission, which implied it was a 4 speed. However,
"second" gear is actually first gear minus the torque
multiplication, which quickly ceases to multiply seconds after
the car starts rolling. This change in ratio on the first
speed was achieved by activating a valve and filling and
unfilling the torus chamber. Very confusing, but you only hear
the transmission shift twice, as a three speed will do.

The EH had a hydramatic behind the red motor. HD was the first with
the powerglide.

In that case, the 4L60 is a 5-speed. :-)
