ATS Diesel 1999-2003 Ford 4wd w/ PTO 4R100 Stage 3 Transmission Package

This transmission package upgrades the factory Ford 4R100, addressing weaknesses in the converter, clutch packs, valve body, and line pressure. It's designed for increased engine power and heavy towing by redesigning these components, increasing line pressure and clutch pack surface area. The Stage 3 includes a billet 300M input shaft for applications exceeding 400hp or heavy towing. It also integrates an ATS Co-Pilot Transmission Lock-up Controller for speed-based converter lock-up, improving acceleration, reducing transmission temperatures, and enhancing fuel economy. The Co-Pilot synchronizes with an exhaust brake. This package is suitable for daily drivers, heavy towing, aggressive tuning, and modified turbos/injectors. No driveline adjustments are needed.
