The internal combustion engine drives two clutch packs.

The inner clutch pack drives gears 2, 4, and 6.

Drive to the front wheels is transmitted through two infinitely-variable clutch packs which are allowed to 'slip' to give the required road wheel speeds.

Power to the each axle is modulated by identical planetary gear sets and electromagnetic clutch packs which can vary incoming power side to side.

Inside the transfer case a multi-row chain drives a multi-plate wet clutch pack.

This pump pressurizes Normal ATF (0-288 psi) into the transfer case to engage the clutch pack.

There were no bands or mechanical holding devices; ratios were supplied by five different clutch packs.

It is strengthened with a reworked final drive unit, barreled axle shafts, and upgraded clutch packs.

Mike Spencer, a spokesman for Honda, said that the five-speed models typically were damaged by premature wear of the third-gear clutch pack.

The clutch pack activates a planetary gearset which causes one wheel to be overdriven.
