Transmission Control Module (TCM)

Solutions

Today’s light vehicle transmissions and gear boxes have become very complex, and are a key contributor to vehicle performance, increased fuel economy, and reduced emissions. Unlike in the past, where a standard gear box moved to 3 or 4 speed automatic transmissions, today’s transmissions may include up to 10 individual gear ratios, requiring complex solenoid control. Additionally, old methodologies have given way to new technologies such as Continuously Variable Transmission (CVT), Dual-Clutch Transmissions (DCT), and Infinitely Variable Transmissions (IVT). Each new technology requires more and more semiconductor content.
