A transmission having a sealing baffle is disclosed. The transmission further includes a transmission case, a torque converter housing and a torque transfer member. The transmission case has a drive sprocket and a driven sprocket mounted for rotation therein. The torque converter housing has a fluid pump for pumping lubrication fluid. The torque converter housing is configured to mount to the transmission case. The torque transfer member is coupled to the drive sprocket and to the driven sprocket for transferring a driving torque from the drive sprocket to the driven sprocket. The first baffle is mounted to the torque converter housing. The first baffle has a base, a first flange extending from a first side of the base, a second flange extending from a second side of the base and a sealing lip formed in the second flange. The sealing lip contacts the transmission case to form a seal to prevent the fluid from flooding the torque transfer member. The seal created by compression of the sealing lip against the transmission case and the subsequent thermal expansion of the baffle and sealing lip is maintained over the entire operating temperature range of the transmission.
