About Us
Your trusted source for high-quality automotive transmission parts, rebuild kits, torque converters, and hard-to-find components — delivered fast and priced right.
Rapid Transmission Supply was built by transmission specialists, for transmission specialists. We got tired of seeing shops and DIY builders overpay for the same parts everyone else sells — so we decided to do something about it. With decades of hands-on experience in the automotive and transmission industry, we source, stock, and ship the exact parts you need from our own U.S.-based warehouses. No middlemen. No inflated markups. Just premium parts at honest prices.
We’re 100% focused on transmissions — that’s it. Every solenoid, seal, clutch pack, and torque converter in our catalog is tested, trusted, and ready to ship the same or next business day. Because we eliminate the layers of distributors and big-box overhead, we consistently beat retail prices without ever compromising quality. Every order is backed by real transmission experts who actually answer the phone, lightning-fast shipping, and a no-hassle return policy. Whether you’re rebuilding a 4L60E in your garage or keeping a fleet of trucks on the road, we’ve got your back.
