Claim 13:
14. The transmission of claim 1, wherein the plurality of selective couplers includes:
a first selective coupler which, when engaged, fixedly couples the input member and the first gearset component of the first planetary gearset to the first gearset component of the third planetary gearset and the first gearset component of the fourth planetary gearset;
a second selective coupler which, when engaged, fixedly couples the input member and the first gearset component of the first planetary gearset to the second gearset component of the third planetary gearset and the third gearset component of the fourth planetary gearset;
a third selective coupler which, when engaged, fixedly couples the third gearset component of the first planetary gearset and the first gearset component of the second planetary gearset to the at least one stationary member;
a fourth selective coupler which, when engaged, fixedly couples the second gearset component of the first planetary gearset, the second gearset component of the second planetary gearset, and the third gearset component of the third planetary gearset to the at least one stationary member;
a fifth selective coupler which, when engaged, fixedly couples the second gearset component of the third planetary gearset and the third gearset component of the fourth planetary gearset to the at least one stationary member;
a sixth selective coupler which, when engaged, fixedly couples the third gearset component of the second planetary gearset to the at least one stationary member;
a seventh selective coupler which, when engaged, fixedly couples the second gearset component of the fifth planetary gearset to the at least one stationary member; and
an eighth selective coupler which, when engaged, fixedly couples the second gearset component of the fourth planetary gearset and the first gearset component of the fifth planetary gearset to the third gearset component of the fifth planetary gearset and the output member.
