Paired with: Ford F-250/F-350, 7.3L IDI Turbo and Power Stroke
Simplified torque-flow diagram — where this transmission sits in the drivetrain, not a literal cutaway of its internals.
The manual option behind the 7.3L through the end of the ninth-generation F-Series, replaced by the heavier-duty ZF S6-650 six-speed when the 1999 Super Duty arrived.
Strengths
- A straightforward, purpose-built heavy-truck manual from a transmission specialist rather than an adapted light-duty unit.
