Introduction

• Transmission Background

• Reason For Transmissions

• How a Transmission Operates– Clutch– Torque Converter

Introduction

• Transmission Control Module– Why is it needed?– Who is it for?– How it works– Extra Features

Introduction

• Justification– Better Performance– Fully Customizable– Reduce Wear and Tear– Inoperable Without the Module

Conceptual Design

Work Plan

Research• Transmissions

– Inputs/Outputs For 4L60-E and 4L80-E

– Wave forms for I/O

• Software– Graphical User Interface in for

multiple OS and mobile devices.– Serial Communication on multiple

platforms [driver creation]– Interrupts for user parameters– Loading program into Flash with

proper initialization– TPU + MIOS for PWM generation– MIOS for the new microcontroller– Interrupt Initialization

• Hardware– Microprocessor for

environment [heat, vibration]– Outputs solenoids and

sensors– Serial Bus – Packaging

Design

• Hardware– Microcontroller Layout– Schematic Design– Signal Conditioning to ensure proper ranges and remove

damaging voltages or currents.

• Software– Develop cross platform software controls for user parameters– Develop the communication protocol from GUI to microcontroller– Develop the task code for microcontroller that considers all

inputs and provides correct PWM outputs

System Integration

Bring Components together: Controller + GUI

•Develop simulated prototype @ bench top

•Test on Dyno

•Deploy to a vehicle with an 4L60-E transmission

Testing

• Hardware– Signal Conditioning Circuits– Inputs to Microcontroller– Outputs to Transmission

• Software– GUI Interface– Microcontroller Code

• Stages– Bench Top– Simulation– Real World Environment

Documentation

• User Manual

• Final Design Schematics

• PCB Layout Design
