29544190 body assembly-valve Allison spare parts

The Allison 29544190 body assembly-valve is a core hydraulic control component of Allison automatic transmissions. It is mainly responsible for transmission oil circuit distribution, pressure regulation, and shift logic execution. It is widely compatible with Allison 3000/4000, 4000RDS, HD/B500, T400 and other heavy-duty transmissions. It is a key replacement assembly for solving shift jerking, vehicle not moving, pressure leakage and slippage, and abnormal noise.
This product is made of high-strength aluminum alloy and precision CNC machined. The internal oil passages are smooth and unobstructed. The valve core fit clearance strictly follows the original factory standard. The whole product has undergone static pressure sealing and durability testing. Under high temperature, high pressure and frequent gear shifting conditions, the pressure is stable, there is no jamming or internal leakage, ensuring smooth clutch engagement and efficient power transmission.
