Which build should I choose for my F-250/F-350?

Daily/light tow → RoadReady. Frequent tow/loaded work truck → StreetMonster. Big torque/tunes or commercial duty → SportMonster.

Is a torque converter included?

Yes—each unit ships with a matched lockup converter (multi-disc options on SportMonster).

What fluid should I run?

Use MERCON V (or your product page’s specified ATF). Always flush/replace cooler & lines at install.

Do I need any relearns after install?

Clear adaptives and perform the PCM relearn/drive cycle for best shift quality.

What are common 4R100 weak points you address?

Diode/overdrive failures, clutch pack wear under heavy tow, and EPC/shift pressure issues—handled via updated components and calibration.

*Axle ratio, tire size, tune, and real-world tow weight affect build choice.
