Straight answers

Will it bolt right in?

Yes. Every Mad Dog unit is a direct bolt-in replacement for your factory transmission — no modifications. Electronic units ship pre-programmed to your VIN, so there’s no dealer visit and no guesswork.

No. Electronic transmissions are pre-programmed to your VIN before they ship. 700R4 units don’t use a computer at all. If your engine is heavily modified, call us and we’ll set the unit up to match.

Most Mad Dog units have no core charge at all. Where a core charge applies (700R4 Godfather, 4L80E, 6L80E/6L90E) it’s listed plainly on the product page — and on the Godfather 700R4 it’s already included in the price.

Call (770) 781-0949 for current build times on your unit. Every transmission is built to your order — your horsepower, your converter, your options — and dyno-tested before it ships.

Every transmission and converter carries a 1-year unlimited-mile warranty, standard. No mileage cap. Extended Silver and Gold coverage is available if you want more. You deal directly with the shop that built it — not a call center.

Then don’t buy it — call us. We build customs to 1,500 HP, and we’d rather steer you to the right unit than sell you the wrong one. Over 800 HP on a 700R4 platform, the answer is the 4L80E.

The hardware that makes a Mad Dog unit 35–40% stronger than factory.

No mystery parts

Steels (All-New)

The complete set of steel reaction plates (‘steels’) replaced as part of the clutch pack rebuild.

Updated Molded Pistons

New, updated-design molded pistons installed on the 6L80E/6L90E rebuild.

Transmission Control Module (TCM)

A new or updated TCM installed as part of a completely rebuilt and updated transmission (6L80E/6L90E builds); an optional paid programming service is also offered.

29-Element Sprag

A 29-element sprag used to prevent reverse rotation of a gear member.

Billet Hub Intermediate Shaft (300mm)

A 300mm intermediate shaft fitted with a billet hub, used on the extreme-duty 6L80E/6L90E ‘Destroyer’ build.

Bushings (All-New)

The complete set of internal bushings replaced as part of the rebuild overhaul kit.

1-2-3-4 and 3-5 Reverse Drum

A new 1-2-3-4 and 3-5 reverse drum, noted as a required replacement because the factory drums are prone to cracking.

Raybestos High-Energy Clutch Pack

Raybestos’s high-energy friction plates use a friction material engineered specifically to survive the higher clutch-to-steel temperatures that come with performance calibrations and repeated hard shifting — conditions that degrade standard OE friction material over time. The result is smoother engagement that holds up over more cycles than a stock clutch pack.

Billet Pump Rotor

High-strength billet pump rotor used on the extreme-duty 6L80E/6L90E ‘Destroyer’ build.

Sonnax #6L80-LB1 Line Pressure Booster Kit

This kit pairs a stronger pressure regulator spring (about 10% over OE) with a large-ratio boost valve. Together they raise line pressure more aggressively as load increases, while keeping idle and light-throttle pressure close to stock — so you get a firmer, more durable shift under power without the harsh idle-engagement feel that comes from oversized springs alone.

Billet Hub Anti-Balloon Plate Triple Disc Torque Converter

Torque converter with billet hub, anti-balloon plate, and triple-disc design for very high horsepower (up to 1000 HP) applications.
