Description
About This Transmission
The Toyota W58 is the 5 speed manual transmission that bolts behind the most beloved Toyota inline six engines of the 1980s and 1990s. Originally factory-fitted in the MA70 Supra (1986 to 1992) behind the 7M-GE and 7M-GTE, the W58 also lives behind the 1JZ-GTE in the JZA70 Supra, the JZZ30 Soarer, and several Cressida and Chaser models. With the appropriate bell-housing adapter, the W58 also serves as the manual swap of choice for the MK4 Lexus SC300 (2JZ-GE), making it the go-to gearbox for an entire generation of Toyota inline six builds.
The W58 uses a fully synchronized 5 speed gear set in a cast aluminum case. All five forward gears synchronize, including 5th, which is overdrive. The transmission rates around 250 lb-ft of torque from the factory, though the JDM and import community has long pushed it well past that figure with proper fluid, clutch, and shifting discipline. For a stock 7M-GTE Supra, a clean W58 will outlast the engine. For a built 1JZ-GTE or 2JZ-GTE making serious power, the R154 is the upgrade path.
Why Toyota Owners Choose a Used W58
W58 cores are getting harder to source as MA70 Supras and Cressidas continue to be parted out worldwide. A clean, gear-tested unit from a verified donor is increasingly the only path forward for owners restoring or refreshing one of these chassis. Used pricing remains far below the cost of full rebuild kits and labor.
Signs You Need a Replacement W58
- Grinding into 2nd or 3rd gear, synchronizer wear (most common W58 failure)
- Pops out of 5th under acceleration, worn shift fork or detent spring
- Whining noise that changes with engine RPM, input shaft bearing wear
- Difficulty engaging reverse, reverse gear or shift rail wear
- Hard shifting cold, fluid contamination or wrong fluid type used previously
- External fluid leak from input or output shaft seals
- Crunch into any gear at high RPM, blocker ring or gear dog wear
Known W58 Issues We Inspect Before Shipping
- 2nd to 3rd synchronizer wear, the highest mileage failure point on this gearbox
- 5th gear pop-out concern on heavily used drift and track units
- Input bearing noise inspection
- Shift fork condition and detent spring tension
- Case sealing surfaces, breather, and tail housing seal
- Bell-housing pattern photographed (7M-series, 1JZ-series, or adapter required for 2JZ-GE)

Vehicle Compatibility
The Toyota W58 was a direct fit in the following vehicles:
| Toyota Supra MA70 | 1986 to 1992 (7M-GE and 7M-GTE) |
|---|---|
| Toyota Supra JZA70 | 1990 to 1992 (1JZ-GTE) |
| Toyota Soarer JZZ30 | 1991 to 2000 (1JZ-GTE) |
| Toyota Cressida MX83 | 1989 to 1992 (7M-GE) |
| Toyota Chaser JZX81 / JZX90 | 1JZ-GTE applications |
| Toyota Mark II / Cresta | Various JZ-powered chassis |
| Lexus SC300 | 1992 to 2000 (2JZ-GE, requires R154 bell-housing or adapter) |
Common swaps: 1JZ-GTE swaps into 240SX, 2JZ-GE swaps into older RWD Toyota chassis, 7M-GE swaps into MA61 chassis. Tell us your chassis, engine, and bell-housing requirement and we confirm the right W58 variant for your build.
Condition and Inspection
Every used W58 we ship goes through this process:
- Gear tested through all 5 forward gears and reverse on test fixture
- Internal visual inspection of synchronizer condition (2nd to 3rd specifically)
- 5th gear engagement tested under load simulation
- Input and output shaft bearing noise check
- Case integrity and sealing surface inspection
- Bell-housing pattern photographed and documented
- Donor application and approximate mileage documented where available
Where donor mileage is verified, it is shared. Where mileage cannot be confirmed, we disclose this before order. Full inspection documentation including photos available on request.

Worn synchros in my MA70 finally gave up. Vaz had a clean W58 with the right 7M bell-housing, gear tested, no synchro issues. Donor history was disclosed. Install was textbook simple. Supra shifts crisp through all 5 gears for the first time in years. Saved me about $1,200 over a rebuild.

Sourcing W58s for 1JZ swaps is getting tough. Vaz had one with confirmed JZ bell pattern, gear tested through all 5 gears, fair price. Communication was excellent through the whole order. Drift car build now has a solid manual gearbox behind the 1JZ. Will buy again.
