ATS Transmission Package for Ford (1989-91) F-250/F-350/F-450 E4OD 2WD Power Stroke, Stage 4

This ATS Stage 4 E4OD transmission package is a complete, matched drivetrain upgrade for 1989-1991 Ford Power Stroke 2WD. Everything in the package is built by ATS to work together, so you are not mixing a built transmission with a stock converter or controller. It is built for trucks with added power that see daily driving, towing, and the occasional hard pull.

ATS Diesel Performance has built diesel transmissions and performance parts since 1993. ATS designs, engineers, and manufactures most of its products in-house at its Arvada, Colorado facility, and tests them at altitude on the same long grades its customers tow on.
