Abstract
A constant mesh gearbox has five parallel rotational axes. The input and output axes are not aligned. Some torque paths are via a sleeve rotatable on a shaft on one of said axes. Up to eight forward speeds are disclosed, with two very low ratios suitable for non-highway travel. The transmission is suitable for two and four wheel drive.

1-14. (canceled)
A constant mesh gearbox having a plurality of individually selectable forward speed ratios, and comprising a casing defining an array of parallel rotational axes, said axes including an input axis, an output axis and a plurality of intermediate axes, and gear pairs for driving between members rotatable on the input axis, the output axis and said intermediate axes, wherein a first shaft is rotatable on one of said intermediate axes, a second shaft is rotatable on another of said intermediate axes, said first and second shafts are directly connected by a first gear wheel pair, a sleeve is rotatable on said second shaft, and said sleeve and said first shaft are directly connected by a second gear wheel pair, and
- wherein said sleeve supports a first gear wheel for rotation thereon, said first gear wheel being selectively connectable for rotation with said sleeve, and being in driving engagement with an input shaft on said input axis.
