Just been looking up the Jatco boxes for all cars
and found that this model L4N71B is not electronically controlled compared to the RL4R01A 4 speed automatic.

electronic control was uncommon until the late 80s. Not sure what they mean by "full hydraulic" since even the stock 3N71B used mechanical (kickdown lever) and vacuum control (the modulator) as well as hydraulics.
L4N71B Swap I would expect it to get better highway fuel economy than a stock 4-speed 1200, since it has overdrive.

JATCO 4N71B series:
* LN471B: Light duty * EN471B: Medium duty The electronically controlled one is the RN4-something. The 4-speed has an extra gear seat between the bell and housing But it has a very short tail housing so overall length appears to be the same. But the rear mount location is farther back.
