Which 66RFE build should I choose?

Daily/light towing and mild tuning → StreetMonster. Frequent towing/hotter tunes/larger tires → SportMonster. Big-power Hemi or performance use → TrackMonster.

Is a torque converter included and matched to my setup?

Yes. Every build includes a matched converter (single, dual, or multi-disc depending on tier) set up for your Hemi, gears, tires, and intended use.

Do I need a Quick Learn/adaptive reset?

Yes—perform Quick Learn and clear adaptives with a capable scan tool, then complete the drive cycle so the TCM can relearn.

What should I replace at install?

Flush/replace the cooler & lines, replace filters, fill with fresh ATF+4, and confirm cooler-flow (no restrictions).

What’s the warranty?

Listed per tier. With Extend, total coverage on transmissions can reach up to 6 years.

*Real-world tow weight, axle ratio, tire size, and tuning affect build selection.
