A power transmission has two selectively engageable input clutches, four
selectively manipulatable synchronizer clutches, and a planetary gearset.
The input clutches and the synchronizer clutches are manipulated to
establish at least seven forward power paths and a reverse power path
between an input shaft and an output shaft. Interchanges between adjacent
speed ratios are controlled by preselecting the synchronizer condition and
then interchanging the selectively engageable input clutches.
