Th 400 Transmission Rear Extension Housing Tail

the Aeroflow performance rear extension housing is designed to replace the stock tail end on an automatic transmission used for high Aeroflow performance and street applications. An extension housing is used to connect the transmission to the drivetrain and connects to a tail shaft which provides power to the wheels. Manufactured from heavy-duty 356-t6 cast aluminium. We recommend to match this with our transmission case (af72-2230) sold separately.
