1999-2003 Ford F250 & F350 7.3L 4R100 ATS Diesel Transmission Package Stage 1 | 3099143224

Able to Handle Much Higher Power than Stock

Your 4WD F250 or F350 Super Duty can handle extra power for days, especially truck's equipped with the 7.3L Powerstroke. Your weakest point however, is your truck's automatic transmission, and stacking on big-time power adders can easily push your factory 4R100 past the point of no return. When you want power without a shredded transmission, you can turn to ATS Diesel and their fully-built Stage 1 4R100 Package. This complete transmission assembly is based on your factory 4R100 and bolts right into place of your factory transmission without any modifications. Unlike your factory transmission, the ATS Stage 1 4R100 can hold up to 450 WHP and high amounts of torque to handle all of your truck's modifications.

Completely Redesigned Internal Parts

ATS hand-assembles each of their Stage 1 4R100s at their Denver headquarters out of high-quality components that allow it to hold much higher power levels than your truck's stock automatic transmission. Every 4R100 has redesigned and upgraded internal components that can handle more power and improve reliability. ATS uses billet steel gear sets, high-quality valve bodies, completely redesigned clutch packs and clutch surfaces that all work together to improve reliability, power-handling, and torque distribution. Keeping the transmission properly lubricated and cool is a much larger oil pump that pulls transmission fluid from an ATS high-capacity, cast-aluminum pan with cooling fins. The higher capacity pump maintains a perfect level of hydraulic pressure even at high levels of power and torque.

Includes 5-Clutch Torque Converter

This ATS Stage 1 transmission comes complete with one of ATS's famous Five Star Viskus torque converters to replace your truck's fairly weak stock converter for even more reliable operation. Each ATS Super Duty torque converter features a high-quality billet housing that doubles up the amount of bolts to the flexplate for improved strength and stability. These ATS torque converters have a five-clutch design that allows them to hold more torque and helps to prevent excess wear that can send metal fragments into your Super Duty's transmission. The converter features a specially designed startor, impeller, and turbine that all work together to reduce heat buildup while holding more power to keep your truck running strong when you stack on a ton of Super Duty performance parts.

Backed by a Legendary ATS Warranty

This transmission package comes 100% complete and ready to bolt onto your truck without any modifications. Both the transmission and ATS torque converter are direct replacements for your stock components and don't require any permanent modifications to your truck for installation. ATS backs each of their transmissions with an unprecedented 5-year/500,000 mile limited warranty to give you even more confidence.

Core charge: a core charge will be applied to every transmission order. ATS sends a container and crating instructions for your factory transmission for shipment to ATS. Once ATS receives your transmission, your core charge will be refunded.
