This transmission is a direct replacement for your vehicle's original unit, ensuring compatibility and proper function. This transmission is shipped via freight only and is restricted to the continental USA. Freight charges are included in the price, and shipping outside the lower 48 United States is not possible.

Built for enthusiasts. Every order is backed by our 30 day return window on eligible items.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
