Abstract

A pawl return spring includes a surface contacting portion adapted to contact a transmission housing. The surface contacting portion includes a first connection region and a second connection region opposite the first connection region. The pawl return spring includes an active coil region connected to the first connection region and disposed about a central longitudinal axis to provide torsional effort to the system. The pawl return spring also includes an inactive coil region connected to the second connection region and disposed about the central longitudinal axis that does not provide torsional effort to the system.
