Identify transmission, year, and early/late six-speed branch before ordering. Automatic transmissions are excluded. Inspect both boots, lower bushing, washers, turret fluid condition, and lever wear rather than assuming one universal kit.
OEM numbers
No universal kit number is claimed. Exact kit contents differ for 1990-1993, 1994-1997, 1999-2005 five-speed, and early/late six-speed assembliesMiata Source identifies an early six-speed VIN boundary below 220738.Supersession
No five-speed-to-six-speed supersession is claimed. Individual boots, bushings, wave washers and turret components must match the transmission/shifter assembly.
Fitment
Identify transmission, year, and early/late six-speed branch before ordering. Automatic transmissions are excluded. Inspect both boots, lower bushing, washers, turret fluid condition, and lever wear rather than assuming one universal kit.
Aftermarket options
OEM-content rebuild kits, specialist complete kits, and individual boot/bushing replacements are valid when matched to the gearbox. Short-shifter conversions are outside this stock-service guide.
Before you buy
A 1999-2005 label is not enough for every gearbox. Confirm five-speed versus six-speed, and early versus late six-speed where the seller specifies a VIN/production split. Automatic parts are excluded.
