Like the C4, C5s were produced as both case-fill and pan-fill with either 157- or 164-tooth flexplates. However, fitment is tricky to impossible in compacts and intermediates, which leaves you with case-fill only. The planetary gear train is the Simpson Design with two gear sets in series yvith a common sun gear. It keeps stray particles from adversly affecting governor operation.
