Daihatsu GRAN MOVE Technical Manual – Factory Transmission Specs

Every time I see a GRAN MOVE come in with a transmission complaint, the first thing I ask the owner is whether the fluid was ever checked to spec. Nine times out of ten the answer is no. But even when the fluid is right, the real problems live inside the hydraulic control system and the electronic logic. Without the Daihatsu GRAN MOVE Technical Manual, you’re relying on guesswork, and guesswork costs billable hours. This is the German-original factory document, 86 pages of nothing but transmission-specific data.

When you’re tearing into the valve body or checking the torque converter freewheel, you need torque values that come from Daihatsu’s engineering team, not some third-party reprint. That’s what this PDF gives you—scanned direct from the OEM binder. I’ve built a whole career on factory manuals like this, and I’ll tell you straight: the aftermarket translations skip steps that get you into a rebuild you didn’t need.

Torque Converter and Power Flow: Factory Procedures

The manual opens with the torque converter specifications and transmission type identification (AT-4). It then diagrams the power flow through the planetary gear sets during each gear range. This is not a generic explanation—it’s the exact hydraulic circuit path Daihatsu designed. If you need to check converter stator operation or measure stall speed, the procedure is in section AT-49. I’ve had technicians waste half a day chasing a slipping clutch when the real problem was a stuck torque converter one-way clutch. The manual’s Kraftfluss section (AT-8) shows you exactly what locks and releases.

Electronic Control System: Wiring and Component Locations

This manual covers the ECAT ECU, solenoid valves, shift solenoids, and the throttle position sensor interface. The system diagram starts on page AT-23, followed by the wiring diagram (Schaltplan) on AT-24. You’ll find the exact locations of electronic components (Lage der elektronischen Bauteile) on AT-25. If the transmission is stuck in limp mode, the Notfahrtfunktion (fail-safe function) explanation on AT-35 tells you which solenoid has dropped out. I’ve used that page to diagnose a bad shift solenoid A without even pulling the pan.

7 Systems Covered – From Overdrive Control to Idle Neutral Logic

The electronic control section alone covers overdrive cut-off (AT-27), lock-up clutch control (AT-27), manual shift operation (AT-28), reverse inhibitor (AT-29), high-speed clutch disconnect (AT-30), throttle linkage control during shifting (AT-30), and idle neutral control (AT-31). Each subsection gives you the logic sequence and the diagnostic outputs. When a customer says the car won’t go into Overdrive, you go straight to Überdriveabschaltung and check the signal from the ECU. No guessing.

Troubleshooting by Fault Codes: Two Tables on Pages AT-46 & AT-47

The Fehlersuche (troubleshooting) section has a step-by-step procedure starting on AT-42, followed by two fault code tables on AT-46 and AT-47. These are the official DTC-to-component cross-references. You’ll also find the diagnostic method for intermittent faults on AT-43. I’ve owned shops where the junior tech would pull a code and replace the solenoid without reading the conditions table – that’s how you get comebacks. The manual tells you what sensors to check before condemning the valve body.

Inspection and Adjustment: Oil Level, Pressure Tests, and Manual Shift Check

Before you disassemble anything, the manual forces you through a sequence of inspections (Prüfung, starting AT-48). That includes torque converter test (AT-49), manual shift test (AT-54), transmission fluid check (AT-55), and a full pressure test based on fault codes (AT-66). The maintenance data on page AT-164 lists all fluid capacities and service intervals. If you skip the oil pressure test because you think the fluid looks clean, you’ll miss a clogged filter – I’ve done it myself once, never again.

Repair Procedures: Valve Body, Oil Pump, and Clutch Pack Overhauls

The Instandsetzungsarbeiten section (from AT-99) walks you through disassembly of the torque converter, removal of the oil pump (AT-109), replacement of the direct clutch C1 (AT-115), overhaul of the overdrive assembly (AT-119), and adjustment of the planetary gear oil clearance (AT-124). It also covers the valve body (AT-138) and the shift cable adjustment (AT-149). Each component section comes with a diagram and the assembly sequence. No assumptions.

What Torque Values Are Listed?

The last section of the manual (AT-167) is a complete torque table – all in Nm, but you can convert to ft-lb with a calculator. Valve body bolts, oil pump housing bolts, converter-to-driveplate bolts, pan bolts, everything. I keep a printed copy of that page taped to my toolbox.

Is this manual specific to the GRAN MOVE automatic transmission only?

Yes. It covers the automatic transmission (A/T) used in the Daihatsu GRAN MOVE. It does not cover the engine, brakes, or body – only the transmission systems: hydraulic control, electronic control, torque converter, and gear train. If you need the engine specs, look for the separate engine manual.

Can I use this for a different Daihatsu model?

No. The design and hydraulic circuits vary between models. The manual is model-specific. For other Daihatsu vehicles, check the related manuals listed below.
