How to use
Orbit: drag. Zoom: scroll or pinch. Pan: right-drag or two-finger drag.
Drive: release the park brake, choose F or R, and raise the throttle. Watch the solenoid LEDs on the valve and the live I/O on the Controller tab.
Inside: set the casing to Solid, See-through, Half section or Removed. Choose a component to isolate it, drag Explode to spread it along its shaft with every part labelled, and hover or tap any part to name it. Step-by-step teardown lays each assembly on the floor in service-manual order. Engaged clutch packs glow amber.
Service: the Controller tab has auto-calibration (needs N, park brake on, and the machine stopped) and the stall test (park brake off; it holds the machine on the service brakes).
Renders: the button at the top opens the path-traced Blender Cycles images.
Faults: inject a fault, then drive to see limp-home and inhibit behaviour.
About this model
This is a representative reconstruction, not a digital twin or a Dana/Spicer drawing. It carries no manufacturer marks and is not validated by Dana.
How it was made
Modelled procedurally in Blender 5.0. The castings are voxel-remeshed, filleted, and hollowed with a 12–13 mm wall, so the cutaway shows a true wall section. The workshop lighting was path-traced in Cycles and baked into the floor and hall. The model is lit by a Cycles-rendered HDR panorama of the same hall, and ambient occlusion is baked into the main castings. Geometry is meshopt-compressed, and everything is embedded in this one file, which works offline.
Published facts it follows
TE32: 270–320 kW input, 2,550 rpm maximum input speed, 4F/4R symmetrical gearing, long-drop output drop of 624.8 mm with ratios 3.90 / 2.22 / 1.32 / 0.72 (TE32424; the short drop TE32418 has 317.8 mm and 5.07 / 2.42 / 1.38 / 0.78), SAE #1 bell on the flanged version, stall torque ratio range 1.78–3.09. Options: electronically controlled modulation, park brake and emergency steer pump (long-drop only).
Proportional (valve-proportional) electronic control. APC-family controllers handle automatic shifting, modulated engagement, inching, shift inhibits, diagnostics and auto-calibration, which runs with the park brake applied.
Service: check oil at 82–93 °C; run automatic calibration every 2000 h.
Sized with the sibling TE30 as a guide: 381/406 mm converter, 2,900 Nm turbine stall torque, about 840 kg.
Inferred or illustrative
The gear train follows the TSM-0064 developed section, power-flow pages and parts groups: the forward and 3rd clutch shafts, the reverse / 2nd clutch shaft and 1st speed shaft, and the 4th clutch shaft and idler shaft each share one axis as two shafts on their own bearings, with a centre web in the case and needle roller bearings where the front shafts run inside the rear ones. The output shaft runs on shimmed taper roller bearings. Return springs follow the reassembly steps. The disc packs match the assembly instructions (3rd and 4th have inner-splined steel discs, outer-splined friction discs and a one-sided friction disc at each end). Only three tooth counts are published (64T 3rd speed gear, 69T 1st speed gear, 55T output gear); the others, and the exact shaft positions, are solved to reproduce the published ratios inside the case.
The gear train is fully kinematic: every gear pair meshes at its true centre distance, every member turns at the speed its meshes and engaged clutches impose, and a slipping clutch shows its drum and hub at different speeds. The simulation uses the modelled ratios (3.91 / 2.21 / 1.31 / 0.72), within 0.6 % of the published long-drop (TE32424) ratios 3.90 / 2.22 / 1.32 / 0.72.
The engine curve (about 300 kW), the converter map, the 17 bar clutch pressure, fill times, shift points, the 5 km/h reversal limit, fault reactions and the heat model are illustrative.
"APC300-style" means a generic APC-family controller. I found no public APC300 datasheet, so its housing, labels and display are generic.
