W56

A common truck transmission that came in 2-wheel and 4-wheel drive varieties. Its ratios differ in comparison to the base W55 in the 1st and 2nd gears only; this is to allow a slightly heavier vehicle (truck) to get up to speed slightly quicker than if geared like a car. This was most likely accomplished by taking the W55 base gears and changing the 1st and 2nd gear sets, as the rest of the transmission remains unchanged.

These include the W56-A (1985), W56-B (1986–88), W56-C (1989–91), W56-D (1992), and W56-E (1993–95) variants of 4WD Toyota Hilux Pickup and 4Runner W56 transmissions.

"; however in its stock form it does not meet all the criteria for a Close-ratio box. The ratio shift was accomplished by taking the W55 base ratios and changing the input shaft to intermediate shaft ratio by 7.9%, thus shifting 1, 2, 3 ratios higher by that amount (4th is direct 1:1). Unlike in the W58 the 5th/overdrive gear set was changed to create a smaller rpm drop between 4th & 5th gears so as to remain close to the overdrive ratio seen in the other boxes. The rest of the transmission remains unchanged.

SC 300s. Toyota lists a change from an alloy sandwich plate to a steel sandwich plate around 1989. The steel sandwich plate has some minor internal differences, and it is believed to be slightly stronger (some wider bearings, some wider gears, slightly different gear selection mechanism, etc.). In theory the all-alloy version of the W58 should be exactly the same strength as any other all-alloy W-Series transmission. The steel plate version is considered much harder to find and worth approximately three to five times as much as an all alloy version. The ratios and bolt patterns remain the same regardless of the sandwich plate used. The W58 & W57 share the highest gearing and closest ratios (1st, 2nd, 3rd, and 4th (direct)) of the stock W-Series transmissions. The ratio shift was accomplished by taking the W55 base ratios and changing the input shaft to intermediate shaft ratio by 7.9%, thus shifting 1, 2, 3 ratios higher by that amount. This also shifted the overdrive 5th gear higher by the same amount creating a wider and taller overdrive ratio. The W58 is sometimes designated as a "

Toyota engineers have shown favor to the W58 over the rest of the 'W' series by including it in so many models and even building a stronger version for higher powered applications.
