  • Patent number: 4526275
    Abstract: A seal kit for preventing the loss of transmission fluid when servicing and/or storing an automatic transmission includes first and second plugs and a retaining strap. The first plug seals the aperture which normally receives the transmission's dipstick. The second plug seals the aperture which is formed when the rearward portion of the transmission is disconnected from the vehicle's drive shaft. This plug has a handle portion and a hollow cylindrical shank having a smooth outer surface which is engaged by the lip seal surrounding this aperture. Finally, a retaining strap having apertures in opposite ends thereof which align with apertures in a flange at the transmission's forward end is secured by means of bolts for example across the forward end of the transmission to secure the torque converter contained therein when the transmission is disconnected from the vehicle's bell housing.
