Item Description
99-05 Mazda MX-5 Miata 6-Speed Manual Transmission MT NB1 NB2 141k 3586
6-speed manual transmission from a 2002 Mazda Miata with 141,052 miles. This was carefully removed from the vehicle and is in good working condition. This transmission was tested prior to removal and shifted through all forward and reverse gears with no abnormal noises, fluid leaks or any other issues. When the transmission was drained the fluid was clean and had no signs of heavy metallic or debris. There is no damage to the case or input shaft outside of normal corrosion and surface rust. The shifter assembly is attached and included, but the rubber boot is torn as has been pictured. The vehicle speed sensor is NOT included. The pictures are of the actual transmission you will receive.
This has been drained of all it's fluids and WILL need refilled with the proper lubricants prior to use.
Fits 1999-2005 Mazda Miata with optional 6-speed transmission as a direct replacement.
This transmission will fit all 90-05 NA/NB 5-speed manuals as a swap but other parts are required.
Freight shipping is available to any address within the lower 48 states. A $75 lift gate service fee will be added to all orders being shipped to an address without a loading dock or forklift. No shipping outside the contiguous 48 states. No P.O. boxes. No international shipping.
