The Transmission Warehouse has embraced its core focus on Country Living in Ontario and Transmissions Only. With decades of dedication to excellence and community involvement, we gained recognition in GEARS Magazine and expanded into a six-bay full-service shop. Now, we are streamlining our services back to concentrate on reliable transmission units and installation only in our new location in at 2223 Hamilton Rd., Trenton ON. 
We rebuild on site all makes and models of automatic Transmissions. We specialize in all truck models, including: - 4L60 / 4L60E for GM half-ton trucks and SUVs- 6L80 6L90 for newer GM trucks - Allison 1000 Series for Duramax-powered HD trucks - 68RFE for Dodge Ram 2500/3500 Cummins trucks. Our transmissions offer exceptional performance with no upselling and fair pricing. After years of service, recognize that customers value access and accuracy over sales pitches, which is why we’ve eliminated unnecessary extras like showrooms and waiting areas. We prioritize what truly matters: correct units clear information, and fitment assistance. If you’re a do-it-yourselfer, we continue to ship across Canada. If you’re uncertain, we’re here to help you confirm your needs. We specialize exclusively in transmissions and installation, built on decades of experience.

No frills. Just Transmissions.
