What does Automatic Gearbox Stage 2 involve?

It is advanced TCU calibration coordinated with a documented engine and gearbox build.

What information must I provide?

The TCU file, service data, parts, engine tune and logs are essential.

Is this service suitable for every vehicle?

Feasibility depends on clutches, cooling, TCU type and actual torque.

How is the result validated?

Validation monitors adaptations, pressure, temperature and slip under progressive load.

TCU Stage 2 is intended for engine and gearbox combinations requiring more than a mild adjustment. It coordinates pressure, clutch, shift and torque strategies around the transmission’s actual capability.

What this service delivers

Coordinated torque control

TCU limits are matched to the engine rather than simply removed.

Advanced strategies

Pressure and shift behaviour are developed as one system.

Thermal validation

Temperature and clutch-slip indicators remain closely monitored.

3
Validation and delivery
Validate under controlled load while monitoring adaptations, temperature and slip.

Requirements

A healthy or suitably upgraded transmission.
Recent servicing and complete engine calibration data.
Reliable TCU logs under controlled load.
