Upgrade Your Factory Valve Body & Restore High-Performance Tolerances
This kit converts any 47RE valve body to a 48RE pressure curve

The original factory cast-aluminum channel plates in Dodge 48RE valve bodies are highly susceptible to warping and distortion over time. Subjected to decades of extreme heat cycles, high hydraulic pressures, and millions of hard shifts, these factory plates lose their flat profile. Once a factory plate distorts, internal cross-leaks develop, bleeding off critical line pressure and causing shift flares or premature clutch failures.
At ATS, we engineered the ultimate high-performance fix: the ATS 48RE Billet Channel Plate Upgrade Kit. By upgrading the flexible factory casting with our rigid, precision-machined billet solution, you permanently restore internal hydraulic integrity and optimize your transmission's shift characteristics.
We don’t just match OEM specifications—we obliterate them. Our billet channel plates are fully machined and finished right here in our machine shop in Arvada, Colorado.
We construct every plate from ATP5 (5083 Aluminum Alloy), a premium, stress-relieved, cast aluminum alloy engineered for:
When we re-engineered the 48RE channel plate, we corrected the flow restrictions left on the table by the original factory design. We completely optimized the internal fluid routing to minimize the volume of area the ATF has to fill.
By streamlining the fluid pathways, we drastically reduced the time it takes for fluid to pressurize the channel from the moment the valve closes to the exact second the clutch packs or bands engage. While this fluid timing difference is measured in hundredths of a second, the real-world performance impact is massive.
The Result? Your transmission locks into 2nd, 3rd, or 4th gear before your engine speed drops out of its optimal power band. You get crisp, clean shifts that put your truck's true power straight to the ground while maximizing component longevity.
Stop relying on weak, distorted factory metal. The ATS 48RE Billet Channel Plate Upgrade Kit delivers a flawless, permanent seal between the channel plate and the main valve body sections, ensuring your transmission runs at peak hydraulic efficiency every single second your truck is running.
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.
