Suzuki Alto / Nissan Pixo Gearbox Removal Repair and Replacement

How to remove and replace a gearbox on a Seventh generation Suzuki Alto or Nissan Pixo.
This particular car is a 2014 car with 27,000 miles. It is the seventh generation HA25 and practically identical to the badge engineered Nissan Pixo. Fitted with the 998cc KA10B 3 cylinder petrol engine and the 5 speed manual gearbox.
In some markets this car might also be called the Mazda Carol or Suzuki Celerio. The gearbox might be called the YC5 or AMF310.

The bearing kit for this box on ebay:

If you can find a reputable gearbox specialist near where you live and have the bearings changed or have the gearbox overhauled but it will cost more. The bearings that went into this gearbox were KOYO bearings. Debate could rage as to whether i should have changed the other bearings and synchros within this box but they all looked and sounded fine.

My attempt at showing the gearbox input shafts being changed, ie a slower version of what appears in this video:
