The 10R140 is the heavy-duty 10-speed transmission
in late-model F-250 and F-350 trucks. We stock reman,
upgraded, and performance-built units ready for
same day installation.
Our Stage 3 10R140 is built for increased torque,
towing, and real-world performance. Upgraded clutches,
a larger deep pan, and proven internal upgrades
to handle the pressure.
