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.
Marlin Czajkowski, owner and CEO of Toyota-specific California-based rock crawling company Marlin Crawler, Inc., invented and popularized an A-through-E nomenclature system for 1985-1995 USA-market W56 transmissions. 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. This system is used to distinguish between the five major design changes Marlin has identified throughout this year span.
Ratios:
- First Gear: 3.954:1
- Second Gear: 2.141:1
- Third Gear: 1.384:1
- Fourth Gear: 1.00:1
- Fifth Gear: 0.85:1
- Reverse: -4.091:1
Applications:
- Toyota Hilux
- Toyota 4Runner
- Toyota T100
