However, most fail just outside of that. The design of this particular transmission was a joint effort between Ford and General Motors. However, we don’t see the wave plate issue with Fords version of this transmission.Ī wave plate is a mostly flat disc that is used in the stack up in a clutch drum. It’s a cushion (spring) for the transition when the clutch drum is applied/engaged. We were more than happy to go along with his train of thought. Our customer found information about the inherent failure of the wave plate in a particular clutch drum in his transmission. A problem we are well aware of.
