Expertly rebuilt Walter Motorsports transmissions, in-stock across the street from Circuit of the Americas!
Two variants, Spec Miata legal boxes and endurance prepped boxes; the endurance prepped boxes feature stronger studs for the gear stack and some other features that are not quite SM-legal. Tired of changing transmissions all the time? Get a Walter and never swap another one again!
Always use Motorcraft synthetic fluid (also available) with these transmissions.
If you're in a hurry call or email to see what our availability is. If you have a cheaper way to ship, send us an email so we can better accomodate you. This software will not calculate freight shipping so an average price has been added into sales. It's always best for us to get a shipping quote and email you an invoice on these transmissions.
