Allison Transmission Holdings (ALSN) Stock Analysis & Winston Score

Allison Transmission makes automatic transmissions for large vehicles like buses, garbage trucks, military vehicles, and construction equipment. The company does not make transmissions for regular passenger cars — it focuses almost entirely on heavy-duty commercial and defense vehicles. Allison is the largest manufacturer of fully automatic transmissions for medium- and heavy-duty commercial vehicles in the world. The company sells its transmissions to vehicle manufacturers, who then build them into finished trucks and equipment sold to governments, cities, and businesses. Most revenue comes from North America, but Allison also sells in Europe, Asia, and other markets. Its moat comes from deep integration with vehicle manufacturers, long product development cycles, and the high cost of switching to a competitor's system. The main risk is that a broader shift toward electric commercial vehicles could reduce demand for traditional automatic transmissions, though Allison is developing its own electrified propulsion products to address that transition.
