29558103 body assembly ,solenoid valve and pin Allison spare parts

The Allison 29558103 body assembly ,solenoid valve and pin is a core electro-hydraulic component of Allison automatic transmissions. It integrates the solenoid valve body, valve core, and signal pin module, and is mainly responsible for transmission oil pressure control, gear shifting, and clutch action execution. It is widely compatible with Allison 3000/4000, 4000RDS, HD/B500 series transmissions, and is a key replacement part for solving shift shock, delay, gear lock-up, and circuit failures.
The product adopts a precision die-cast valve body and wear-resistant valve core structure, and the pin terminals are gold-plated, which ensures stable conductivity, corrosion resistance and oxidation resistance. The whole product has undergone rigorous pressure and circuit testing. Under high temperature and high frequency operating conditions, it responds quickly, does not leak oil or jam, and ensures that the transmission electronic control system and hydraulic system work together precisely.
