A Transaxle combines the transmission, differential, and ancillary systems around the axle into one integrated assembly. You will usually find transaxle configurations in cars where the engine is placed at the same end of the car as the drive wheels.

Oil seals are used to protect shafts and bearings from ingress of dirt and foreign matter and egress of oil or grease. An oil seal generally consists of an outer circular metal part and an inner flexible member that does the actual sealing and is bonded to the metal part by chemical adhesive agents.
