Isuzu C&E Series 2011MY MJX Transmission Workshop Manual

This Isuzu C&E Series 2011MY MJX Transmission Workshop Manual (document number HGMJX-WE-1091) is the complete service and repair guide for the MJX16 manual transmission as fitted to 2011 model year Isuzu C and E Series trucks. Whether you are rebuilding the 16-speed overdrive transmission, servicing the 15.5 inch twin plate pull type clutch, or diagnosing a fault in the side power take-off system, this manual gives you the procedures, specifications, and torque values needed to get the job done correctly.

Written for professional technicians and experienced owner-operators, the manual follows the factory approach to disassembly, inspection, repair, and reassembly. Every major assembly is broken down into its component parts with clear instructions on handling, measurement, and reassembly order. From the input shaft and main shaft to the range change case and splitter mechanism, this is the document you want open on the bench when working on an MJX16 gearbox.

The manual opens with the transmission’s function and operation, including the lubricant system diagram and the transmission control system layout. From there it moves into the main data and specifications — gear ratios across all 16 speeds, dry weight, lubricating oil capacity, and gear mesh type. Troubleshooting charts cover abnormal noise, hard shifting, walking or jumping out of gear, and oil leakage, each with possible causes and corrections. Service standards list the wear limits for synchronizer inserts, clutch hub clearances, shift arm thickness, detent spring free length, and control rod lengths.

The disassembly and reassembly section walks through the entire transmission in a logical sequence: drain and fill procedures, periphery parts, transmission assembly, input shaft, main shaft, counter shaft, output shaft, shift rod, covers, upper quadrant box, and power assister. Each sub-assembly has its own component diagram, step-by-step disassembly, reassembly with setting marks and grease application points, and inspection and repair criteria. Fixing torque charts are provided throughout so you are never guessing at bolt and nut values.

The clutch section covers the 15.5 inch twin plate pull type clutch used behind the MJX16, including clutch cover and intermediate plate inspection, clutch disc wear checks, release bearing and shift block service, clutch pedal and master cylinder removal and installation, and a complete clutch booster overhaul with greasing chart. The side PTO section covers the air-controlled side power take-off, including the shift cylinder, shift rod, output gear, clutch sleeve, and output flange, with preload adjustment procedures and shim selection tables.

What This Manual Enables You to Do

With this Isuzu MJX16 transmission workshop manual, you can perform a complete transmission overhaul — removing the unit, disassembling every sub-assembly, measuring wear against factory service limits, replacing bearings, synchronizers, gears, seals, and shift components, and reassembling to correct clearances and torque values. You can diagnose and repair shifting problems, noise complaints, oil leaks, and range or splitter faults. You can service the clutch, including disc replacement, release bearing replacement, master cylinder overhaul, and clutch booster rebuild. You can also repair or overhaul the side power take-off, including bearing preload adjustment and shift cylinder service.

Having the correct procedures and specifications matters because the MJX16 is a complex 16-speed transmission with range change and splitter mechanisms. Getting the synchronizer assembly order wrong, missing an interlock ball, or failing to adjust bearing preload correctly can lead to premature failure, difficult shifting, or total transmission loss. This manual gives you the setting marks, installation directions, grease types, torque sequences, and service limits that keep the job right the first time.
