Replace during clutch pack service if the spring is cracked, flattened, heat-damaged, distorted, or if clutch engagement problems are traced to worn clutch assembly components.
Installation Notes

Parts Desk Insight
This is a small but important clutch-pack part. The transmission tag and exploded diagram matter more than the general Borg-Warner name, because similar clutch assemblies can use different spring stacks.
