Part of the John Deere Repair Manuals.
This is CTM84, the Funk component technical manual for the DF150 and DF250 powershift torque-converter transmissions with digital electronic control. It covers the whole box from drive plate to output yoke: torque converter with fixed and free stator, charge pump and suction tube group, front cover input and idler gears, control valve with its cap screw tightening sequence and pressure/temperature check ports, clutch stage assemblies, disc brake group, and the digital Transmission Control Unit. You get the full ratings tables (DF150 at 142 kW/190 SAE hp, DF250 at 224 kW/300 SAE hp), fastener torque charts, symptom/problem/solution troubleshooting, clutch calibration, and TCU diagnostic coverage. If you are rebuilding or diagnosing one of these Funk boxes, this is the factory paper you want on the bench. This PDF actually bundles five factory publications: CTM84 (digital-control DF150/DF250, the main procedures above), a CTM148 analog-control supplement for the DF150, and CTM157 with full transmission wiring harness diagrams for the TCU system.
