Unified Hydraulics and Mechanics Simulation
Model hydraulic circuits and mechanical components together in one environment. This eliminates co-simulation overhead for faster, more accurate predictions of clutch engagement and shift behavior.
GT-SUITE is the ideal tool for evaluating transmission component and system design and controls.
Solution Overview
Accurate Powertrain Predictions
GT-SUITE allows complete transmission system simulation, including shift strategy generation, powerflow specification, thermal warmup and lubrication studies, and shift quality and noise, vibration and harshness (NVH) evaluations.
Through integration with other GT-SUITE libraries, such as engine and vehicle, completely predictive powertrain models can be generated. Additional modeling detail can be added through the general multibody dynamics GT-SUITE library, which enables evaluation of more detailed component-level behavior, including finite element models.

Advanced Features
Integrated Transmission Design and Analysis Tools
Accelerate transmission development with comprehensive simulation tools for design, optimization, and validation.
Transmission Components Design & Analysis
Performance evaluation of complete topologies and/or individual components including driveline torsional dampers, dry and wet clutches, gear sets, shift mechanism, dog clutches, synchronizers and park locks.
Scalable Fidelity: From 1D System to Full FE Models
Extend models from efficient 1D simulation to 2D/3D and finite element representations without rebuilding the architecture, adding structural detail precisely where it's needed.
Predictive Electro-Magnetic Solenoid Modeling
Simulate the electrical and magnetic behavior of solenoids to predict actuation force and response with high accuracy. This enables fully predictive hydraulic control system design without relying on simplified lookup tables.
Component-Level Thermal Analysis
Capture thermal behavior of individual components, including clutches, gears, and bearings, to evaluate heat generation, thermal limits, and warm-up performance within the full system model.
CAD-Integrated Model Building and Visualization
Use GEM3D and SpaceClaim to discretize hydraulic flow paths directly from CAD geometry, then visualize gear and synchronizer behavior with dedicated output tools. This reduces setup time and improves result interpretation.
