A power-shift countershaft type transmission comprising:
- a transmission housing having a first end wall and a second end wall which is releasably secured to said housing in spaced relationship to said first end wall,
- said first and second end walls each having aligned bearing bores therein for rotatably supporting power transmission means,
- a dividing wall formed within said housing in a position between said first and second end wall to form a main rotating components compartment and a sump compartment,
- power transmission means rotatably supported by said first and second end wall bearing bores providing forward, reverse, and change-speed transmission of power,
- control means operatively connected to said transmission for selectively controlling the transmission of power from said power transmission means, and
- fluid transfer means coupled between said main rotating components compartment and said sump compartment, for transferring fluid therebetween to operate said power transmission means in a substantially splash-free environment.
