AZ2220010080A Transmission Middle Housing is a supporting component of the transmission front housing series, compatible with SINOTRUK HW25712 series heavy-duty truck automatic transmissions.

Adopting high-quality aluminum alloy integral die-casting molding, it balances lightweight performance and structural rigidity with excellent heat dissipation. It resists deformation and cracking under high-load driving conditions.

The joint faces and mounting holes of the housing are processed by precision CNC machining with strict dimensional tolerances, enabling precise alignment and tight fitting with the front and rear housings.

Designed with a reasonable integral sealing structure, it effectively retains internal lubricating oil and prevents oil leakage and dust accumulation.

It firmly supports precision transmission parts such as internal gears and shaft assemblies, buffers operating vibration and reduces working noise. Complying with original factory assembly standards, it features high compatibility and easy assembly and disassembly, being a premium replacement part for heavy-duty truck transmission maintenance.
