Fits 1999-2003 Ford Power Stroke – Upgrade to the Legendary Allison Transmission Without the Fabrication Nightmare.
For years, 7.3L Power Stroke owners looking to swap out the restrictive factory 4R100 transmission faced a frustrating compromise: settling for an outdated analog Allison swap that required hacked-up driveshafts, relocated crossmembers, and unchangeable, clunky industrial tuning.
ATS has completely rewritten the script. Our engineers designed this conversion kit to place your factory Ford transfer case in its exact stock location. By engineering custom, application-specific components from scratch rather than stacking universal aftermarket adapters, we’ve created a seamless, bolt-on conversion that retains your stock front and rear drivelines and factory crossmember—saving you thousands of dollars in secondary modification and fabrication costs.
The biggest breakthrough in the ATS system is the electronics. While competitor kits force you to use an ancient, un-tunable industrial TCM (often permanently locked to 5.13 differential gears), ATS utilizes a cutting-edge Translator Module. Instead of relying on non-existent real-time digital data from the factory Ford ECM, the ATS Translator captures raw analog inputs directly from the truck and calculates its own precise data stream to communicate seamlessly with a modern GM T87 TCM.
This standalone capability allows us to utilize the advanced Gen5 (2019+) Allison valve body instead of low-line pressure trim valves. Your kit arrives with an unlocked T87 TCM pre-calibrated for your truck's specific setup. Because it is completely unlocked, you have full access via HP Tuners software to adjust shift points, line pressure, and torque converter lockup to perfectly match your driving style, tire size, and power levels.
✓ No Driveline Modifications: Keeps your factory transfer case and crossmember in the exact stock 4R100 position. No cutting or lengthening of front/rear driveshafts required.
✓ Heavy-Duty Billet Output Shaft: Custom ATS billet output shaft splines directly to your factory Ford transfer case, eliminating weak multi-piece adapter shafts.
✓ Full-Size Torque Converter: Features a custom adapter plate that bolts to the 7.3L block and adapts to an SAE4 bellhousing. This allows the use of a full-size torque converter with the exact Stall Torque Ratio (STR) the 7.3L Power Stroke demands.
✓ Billet Converter Cover: Seamlessly connects to your factory Ford flexplate for a clean, simple, and ultra-strong installation.
✓ ATS Gateway Software: Includes proprietary software allowing you to connect directly to the translator module via laptop. Because the system processes raw analog data independently, this software lets you effortlessly view real-time transmission data and calibrate the Throttle Position Sensor (TPS) inputs, factory Tow/Haul button, and Tap Up/Tap Down manual shifting buttons.

ATS Transmission packages carry a standard THREE YEAR Warranty. There are several exceptions, so refer to the Warranty’s specific terms and conditions . All labor, shipping, or any other charges associated with the product and the product’s failure are not covered under Warranty. Labor and/or shipping charges will not be refunded under any circumstance. After the one-year anniversary date of the original purchase, there is a limited parts replacement Warranty only. Transmissions that are purchased separately outside of a transmission package / stage and are installed without an ATS torque converter carry a 1 year parts only warranty and there is no labor or shipping allowance for transmission only purchases.
In the event of a product failure, the consumer must return the defective product to ATS for inspection before a replacement is sent to the consumer. After ATS inspects the product and completes the failure analysis, the inspection officer at ATS will provide written documentation stating the condition of the product and determine, to the best of his or her ability, what caused the malfunction or complaint. Based on the findings of the inspection report, ATS will determine whether there is a valid Warranty claim. Should a consumer require immediate service, and chooses not to wait for their product to be returned to ATS for inspection, service, and potential repair or replacement, the consumer can purchase a replacement product from ATS. The consumer must pay the full current MSRP, the applicable core charge, and shipping to and from ATS’ shop. When the defective product arrives, ATS will refund the core charge and inspect the product. During inspection, ATS will assess the product for warrantable damage. If the original product has indeed failed under the terms of the original Warranty, ATS will refund the full purchase price for the replacement product only. If the product has failed due to any issue not covered under the original Warranty, ATS will assess charges to the consumer based on any parts necessary to return the product to nominal ATS standards. ATS will deduct the total cost of required parts from the replacement product’s purchase price, and the consumer will be refunded the difference (if any) between the purchase price paid for the replacement product and the cost of parts.
If the consumer can wait for their product to be returned to ATS for inspection, service, and potential repair or replacement, the consumer pays shipping to and from ATS’ shop. When the defective product arrives in Colorado, ATS will inspect the product. ATS will then assess the product for warrantable damage. If the product has failed under the terms of the original Warranty contract, ATS will repair or replace the product – at ATS’s discretion. If the product has failed due to any issue not covered under the original Warranty, ATS will assess charges to the consumer based on any parts necessary to return the product to nominal ATS standards. ATS will bill the consumer for the total cost of parts required for repair of the product, and shipping to and from Colorado, prior to the repaired/replaced product being sent to the consumer.
This section incorporates Section 2, entitled “In the Event of a Failure.” ATS manual transmissions carry a 1-year/12,000 mile Warranty. ATS will not pay for any fluids replaced in the event of a transmission failure. There is no labor or freight warranty coverage on standard transmissions. Manual transmission shafts and gears are not covered by this Warranty on any transmission due to the capability of certain situations to cause stress-loads beyond the structural ability of the shaft or gear.
