Sort of but no... These transmissions are "sort of pregnant"
They do have 4 fluid paths with 4 ratios out the tail shaft but one of them is only a fluid dump and that is for a split second, it is not a "gear" shift. You can not feel 4 speeds and the gear selector only shows 3 speeds.
If someone gives $80K for it, my wife's original paint 62 will be for sale.... Boy will my wife be mad.

No, what they really had was an early version of the switch pitch fluid coupling. Olds called this a "4S" transmission (not a four "speed" transmission), and as Eric points out, the CSM lists four different "gear ratios", but the reality is that first and second are really with and without the fluid coupling multiplier. It's interesting that in 1961, Olds only showed three speeds, but in 1962 the exact same trans with the exact same gear sets suddenly was a "4S" thorough the miracle of the marketing dept.
The RH5 is a weird automatic. It does not have a conventional torque converter. The input shaft looks like the one on a manual, and the flywheel (it's not a flexplate) has a spring-loaded center hub like the middle of a clutch disk. There IS a fluid coupling in about the middle of the trans, and as I noted, it can either lock or unlock the stator blades, thus providing the two different multiplication ratios from first to second. Interestingly, third (which is really the second gear set and the "S" position on the shifter) bypasses the fluid coupling and is directly driven from the engine. If you drive slowly in this gear, you feel it lugging just like a manual trans. Fourth (the third gear set and the "D" position) is 1:1 but does use the fluid coupling.
Joe, I believe the 61 only had 3 fluid paths and a different valve body. Although they were nearly identical and almost all of it will interchange, there was a slight difference. I would have to look it up but I think there was something about this in one of the Service Guilds. I think the governor was also different between 61 and 62/63 but not 100% sure if that.
