Gearboxes are not easily replaced with manual ones, the whole engine/gearbox unit needs to be changed.
Late Rover 1275 auto block can be converted to work on a manual box, but not easily.
Recent excerpt from my block conversion thread-
"UPDATE re late Rover Mini automatic block-
Doogie brought one round today.
These don't have the oil filter mounting pad angled drilling which goes up into the main oil gallery on all A series & early A+ manual blocks (and all the A series auto blocks have too).
I cannot do these A+ auto ones with my equipment.
It isn't impossible to do, but really needs a mill with tilting head and careful jigging, or preferably a CNC mill. There is not much room for error here.....
So hardly worth doing, it's far easier to go find a manual block or an early auto one."
