Allison Transmission makes fully automatic transmissions for medium- and heavy-duty commercial vehicles, including refuse trucks, construction trucks and buses. Vehicle manufacturers buy its systems and install them in vehicles, either as the exclusive offering or because the buyer requests Allison. Before its recent off-highway acquisition, road-going vehicles supplied most revenue, with North America the largest market; long-haul highway tractors were only a limited part of the business.
Once vehicles enter service, maintenance and repairs generate further sales of Allison-branded parts, transmission fluids and remanufactured systems through independent distributors and dealers. This installed base supports a relatively steady aftermarket business, while new-system sales depend on vehicle purchases and manufacturers continuing to offer Allison products. Revenue is concentrated among a few vehicle manufacturers, notably Daimler, PACCAR and Traton.
Allison also supplies propulsion systems for military vehicles, selling to governments and their contractors. This business is subject to export-control and government-procurement rules.
The acquisition of Dana’s off-highway business expanded Allison beyond its earlier business mix. It now operates Allison Transmission and Allison Off-Highway Drive & Motion Systems as two business units.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Beyond this list, watch Daimler AG and Traton SE, which accounted for 18% and 10% of Allison’s 2025 sales, and ZF, an important off-highway competitor.
Allison depends directly on PACCAR’s truck purchases: PACCAR builds commercial trucks using Allison transmissions and accounted for 11% of Allison’s 2025 sales. Watch its medium-duty and heavy-duty vocational truck production rather than treating all truck sales as equally relevant to Allison.
Cummins competes for commercial-vehicle makers’ spending with engines, drivetrain systems and transmissions, while Allison sells automatic transmissions and hybrid and electric propulsion systems. Its Components business is the place to watch for competition in drivetrain systems and transmissions, rather than its broader power-generation business.
Dana competes with Allison to supply commercial-vehicle makers with products that drive their vehicles, but also sold Allison its off-highway business, acquired on January 1, 2026. Dana’s Commercial Vehicle sales are the more relevant comparison; its larger Light Vehicle business serves a different market.
Oshkosh’s production of vocational and military vehicles feeds demand for Allison transmissions installed in those vehicles. Its production news in those two vehicle groups is therefore relevant to Allison’s component demand.
Blue Bird Corporation buys Allison transmissions for the school buses it manufactures and sells, linking its bus production to Allison’s school-bus demand. Watch its Bus segment revenue rather than replacement-parts sales for a read on that new-vehicle market.
Twin Disc competes with Allison for off-highway energy and specialty-vehicle transmission business, where Allison sells to vehicle makers and distributors. Watch Twin Disc’s heavy-duty off-highway transmission business; its marine products are not the same competitive overlap.
Caterpillar competes with Allison by selling off-highway equipment with integrated drivetrain products, while Allison supplies transmissions to equipment makers and distributors. Its energy, mining and construction equipment business is the relevant area to watch, with the cited rivalry covering North America in 2025.
Eaton competes for commercial-truck transmission business against Allison’s automatic transmissions. Electrical products dominate Eaton’s broader business, so its overall results are not a clean guide to this truck-market rivalry.
Rush Enterprises’ truck sales and fleet repair business give two readings on demand for Allison’s transmissions and replacement parts: Rush sells and services commercial vehicles, while Allison supplies their propulsion equipment. Watch new-truck revenue for vehicle demand and parts-and-service revenue for ongoing maintenance, which is generally less cyclical.
Atmus Filtration Technologies’ replacement-filter sales reflect maintenance by truck, bus and off-highway fleets whose operation also creates demand for Allison transmission parts. Replacement and repair parts generated about 86% of Atmus’ 2025 net sales, making that revenue a more useful maintenance signal than filters installed in new equipment.
Commercial Vehicle Group shares Allison’s exposure to commercial-vehicle production: manufacturers buy its seats, electrical systems and trim, while Allison supplies transmissions. The connection is demand for different components in vehicle production, not competition between their products.
Paccar Inc earningsPCAR
PACCAR’s report will show how production of medium-duty and heavy-duty vocational trucks is changing, a signal of demand from a major Allison Transmission customer.
Focus on PACCAR’s medium-duty and heavy-duty vocational truck production. Rising production would point to support for demand in Allison Transmission’s North American on-highway business; falling production would signal pressure on that demand. PACCAR accounted for 11% of Allison Transmission’s 2025 sales, but its production is not a substitute for Allison’s own shipment figures.
Rush Enterprises Inc earningsRUSHA
Rush Enterprises’ report pairs new-truck sales with repair and service activity, showing how fleet purchases and upkeep relate to demand for Allison Transmission’s transmissions and parts.
Compare Rush Enterprises’ new-truck revenue with its parts-and-service revenue. Strength in both would indicate that fleets are buying vehicles as well as maintaining the ones they already operate, offering two demand signals for Allison Transmission’s installed transmissions and replacement parts. If new-truck revenue weakens while service holds up, maintenance is cushioning weaker new-vehicle demand, not showing that it has recovered.
Fed Interest Rate Decision
Allison’s Fed policy-rate reading tracks the cost of borrowing across the economy; higher rates can raise interest on its variable-rate credit-facility debt and acquisition borrowing, leaving less operating cash for production, investment and debt service.
Expected4.0%Last release4.0%
If it comes in above expectations
If rates rise more than expected, Allison may pay more interest on debt that reprices and new borrowing, leaving less cash for manufacturing and other operating needs.
If it comes in below expectations
If rates rise less than expected or fall, Allison’s interest burden on repricing debt and new borrowing may be lower, preserving more cash for operations and investment.
ALLISON TRANSMISSION HOLDINGS, INC. earningsThis company
Allison Transmission’s report will show whether North American on-highway sales and service-parts sales support its gross margin.
Read North American on-highway sales and service-parts sales alongside gross margin. If both sales hold up and margin stays firm, demand and the mix of products sold are supporting profitability. If sales weaken and margin falls too, pricing, product mix or costs are not offsetting the demand pressure. Together, these figures show whether Allison Transmission’s core business is holding up.
Oshkosh Corp. earningsOSK
Oshkosh’s report will show production trends for vocational and military vehicles, indicating demand for vehicle applications that use Allison Transmission products.
Watch Oshkosh’s production of vocational and military vehicles. Higher production in either group would point to stronger demand for vehicle applications that use Allison Transmission products; lower production would weaken that signal. Oshkosh’s production reflects demand in those markets, not Allison’s own shipments.
Eaton Corporation, plc earningsETN
If Eaton reports on its commercial-truck transmission business, its results will show how it is competing with Allison Transmission for truck makers’ business.
If Eaton breaks out commercial-truck transmission sales or activity, read that rather than treating its overall results—dominated by electrical products—as a measure of this rivalry. Strength in the relevant business would signal tougher competition for truck makers’ orders; weakness would soften that signal, but would not mean Allison won those orders. The takeaway is the intensity of competition in the shared market, not Allison’s actual gains or losses.
Blue Bird Corporation earningsBLBD
Blue Bird’s report will show how school-bus demand is changing in a market where its buses use Allison Transmission products.
Watch revenue in Blue Bird’s Bus segment, which is a better read on new school-bus demand than replacement-parts sales. Higher revenue would show support from the new-bus market for vehicle applications served by Allison Transmission; lower revenue would mean less support from that market. Blue Bird’s revenue is not Allison’s sales, so the conclusion is limited to this vehicle category’s demand.
