A variable automatic transmission for a motor vehicle comprising:
- a housing;
- a frusto-conical driven gear having a plurality of spaced apart teeth on one surface thereof and a hollow opening therein extending the length thereof and rotatably disposed within said housing;
- a first main power shaft having a plurality of sliding face gears slidably supported thereon wherein a first of said plurality of sliding face gears is adapted to engage an input gear from an engine and a second of said plurality of sliding face gears is a driving gear with a plurality of complimentary spaced apart teeth for engaging the plurality of spaced apart teeth of said frustro-conical gear;
- and
- wherein said plurality of complimentary teeth on said frustro-conical gear include a plurality of teeth having a first addendum and a plurality of complimentary teeth having a larger addendum and wherein said teeth on said driving gear form a plurality of shallow teeth receiving openings for receiving and engaging said complimentary teeth having a first addendum, and a plurality of relatively deep openings for receiving said complimentary teeth having a larger addendum and separating said shallow teeth receiving openings.
