ABSTRACT:
A power transmission has a torque converter, a planetary gear arrangement and a variable ratio drive belt. The planetary gear arrangement is controlled to establish a low forward ratio and a reverse ratio. The variable ratio belt drive is controlled to provide a variable ratio high speed range. A torque converter is utilized during the low forward ratio and the reverse ratio and is selectively bypassed during the high speed range.
