	EM57 gearboxes have been found to feature open bearings (probably earlier variants) as well as rubber sealed bearings. There has been reports of open bearings failing especially with prolonged running in reverse direction.
			EM57 gearboxes have been found to feature open bearings (probably earlier variants) as well as rubber sealed bearings. There has been reports of open bearings failing prematurely especially with prolonged running in reverse direction which causes the splash lubrication not to function properly. Therefore it in advisable to pay attention to regular oil changes and use good quality oil with the gearbox.

			Nissan's specs for oil volumes are 1.35 and 1.4L depending on the variant of the gearbox.

	The Nissan Leaf uses a single gear reduction ~~box~~.		The Nissan Leaf gearbox uses a single gear reduction and differential for transmitting power from the motor to the drive shafts. The gearbox also houses an electronic parking break mechanism which locks the input shaft from spinning via a solenoid operated lever. There is no oil pump and lubrication is provided by a splash lubrication system.

			The input splines are the same on both the EM61 and EM57 motors, but the bolt pattern is different. This means that you cannot use an EM61 motor with a EM57 gear box and vice versa. For more details on bolt patterns see [[Nissan leaf motor couplers and adapter plates]].
