Abstract
A seal for use between the housing of an automatic transmission and the housing (can) of a transmission drive motor is disposed at each end of the drive motor housing. The seal includes a preferably metal annulus having inner and outer elastomeric ribbed seals secured thereto. The annulus, which defines a non-hardened 'S' shape in cross section, maintains the shape and strength of the seal and the ribbed inner seal provides a fluid tight seal with the motor housing while the ribbed outer seal provides a fluid tight seal with the transmission housing.
