1. A lubricant transfer arrangement for a lubricant supply for a transmission, the lubricant transfer arrangement comprising:
an outer transmission component;
an inner transmission component rotatable relative to the outer transmission component;
a plain bearing supporting the outer transmission component on the inner transmission component;
a lubricant pocket formed between the outer transmission component or the inner transmission component and the plain bearing;
a lubricant channel designed to lead through the outer transmission component, the plain bearing and the inner transmission component to supply a transmission element to be lubricated provided at a downstream end of the lubricant channel, said lubricant channel running past the lubricant pocket; and
a leakage groove formed between the outer transmission component or the inner transmission component and the plain bearing to fluidically connect the lubricant channel to the lubricant pocket.
