29537437 Cover, Rear Allison spare parts

The Allison 29537437 Cover, Rear is specifically designed for Allison automatic transmissions in heavy commercial vehicles, engineering vehicles, and special vehicles. It is primarily compatible with Allison 5000/6000 series automatic transmissions and is widely used in various scenarios that rely on transmission stability and protection, such as long-haul trucks, public buses, and construction machinery. It perfectly meets the core needs of repair shops, parts dealers, fleet maintenance, and engineering equipment maintenance, and is a high-quality solution for rear cover damage, seal failure, dust intrusion, and hydraulic oil leakage.
This product strictly adheres to Allison’s stringent production standards, inheriting the brand’s technological advantages in the field of heavy-duty automatic transmissions. It is precision cast from high-strength ductile iron, which significantly improves tensile strength, deformation resistance, and sealing performance compared to ordinary cast iron covers. It can easily withstand vibrations and impacts during vehicle operation, as well as hydraulic pressure inside the transmission, providing a robust protective barrier for precision components such as planetary gears and clutches at the rear of the transmission.
