This is the factory repair manual for the New Holland TJ275, TJ325, TJ375, and TJ450 articulated 4WD tractors. It covers both engines used in the line - the CDC 6TAA-8304/9004 in the TJ275/325 and the Cummins QSX 15 in the TJ375/450 - plus both transmissions: the 24-speed constant-mesh manual and the 16-speed full powershift. You get the schematic foldouts that matter on these tractors, split by serial number: manual transmission before/after RVS002701 and hydraulics before/after RVS001801. Sections run from engine and transmission through PTO, brakes, Megaflow hydraulics, articulation frames, steering, axles, cab climate control (including ATC), and full electrical schematics with harness and connector detail. Torque spec tables for standard, metric, and hydraulic fittings are up front.
