This is the transmission that couldn't be built until now, because the parts weren't available. As the 700R4 transmission becomes more and more popular, stronger parts come on the market. This transmission has every heavy duty / high performance part on the market plus all of the tricks we've learned in our sixteen years of building high performance / heavy duty 700R4 transmissions. This is the strongest 700R4 transmission that can be built bar-none. If it doesn't have it, it can be added as an extra. Here are some of the parts that come as standard on the 700 Mega Raptor. You get everything that comes with the 700 Raptor plus the Torque Drive Package, Torque Master Package and the five pinion OEM GM planet gears. This transmission is good for any type of heavy duty / performance use up to 700 horse power / 700 foot pounds of torque using pump gasoline, 4WD, towing, street rods, drag racing, big block, one tons and others. See ratings chart below.

Extreme Duty Torque Drive Package. You get a hardened input shaft and drum assembly plus a hardened reaction shell and bearing. Every time you think there's nothing else that can be done to a 700R4, here it comes. These parts are made to with-stand way over 600 foot pounds of torque. Fits late 1987 up. 

Drum: Starting with select cores, the input shaft / drum assembly is disassembled and visually inspected. Then super heated until fully expanded and then X-rayed for internal cracks. Heating the drum collapses any carbon pockets thus ultimately strengthening the cast and stabilizes it. This process is followed by a flux test to determine if any external fractures are present. If all checks well a specially machined alloy support ring is then married to the drum.

Shaft: The shaft is cold and hot chemically forge treated to a military standard Rockwell 38 hardness. Then stress relieved which gives the shaft double the strength of its stock counterpart. The parts are reassembled and spun balanced at 9500 RPM. This step insures that this assembled unit will spin true with absolutely no harmonic vibrations to disturb engaging parts. Stock factory units were never balanced to this degree. The input shaft / drum assembly comes with a specially machined over-run piston and high temperature seal.

Extreme Duty Shell / Bearing Assembly: A new reaction shell is provided with a reinforced hub that is approximately twice the thickness of an OEM reaction shell. The reaction shell is hardened then spun balanced at 9500 RPM. We replace the OEM plastic thrust washer with a roller thrust bearing to reduce heat. A specially machined and hardened rear planetary inner race is included to complete the assembly.

This is the hot new item on the street, for high performance, towing and heavy vehicles. Twice as strong as the stock parts.

Extreme Duty reaction carrier shaft with bearings (Torque Master Package). This shaft and hub attaches to the rear planet gear. The old style shaft uses thrust washers where as the new style shaft is machined to accept thrust needle bearings. This three piece kit comes with the shaft and two thrust needle bearings. This was the last part needed making it possible to build the entire transmission without the use of thrust washers. Ask our competition if their transmission contains this part. This reaction carrier shaft was designed for the increased torque load of the 6.0L version of the Gen III V-8, as well as Corvette's LS6 engine. Fit 1982 to 2004, 700R4 and 4L60E transmissions.

Extreme Duty planet gears with 5 pinion gears. These two planet gears are twenty years past due, this has always been a weak point on the 700R4 transmissions. These are new OEM planet gears, not after market or GM rejects. After market five pinion planets will not work. These 5 pinion 2002 type GM gears are at least 25% stronger than the old type. The use of five pinion gears for the input and reaction gear sets spreads the torque load so that less of the load is held by any one gear. These gears are made of powdered metal, which GM claims allows for a higher overall strength. This five pinion reaction carrier was designed for the increased torque load of the 6.0L version of the Gen III V-8, as well as Corvette's LS6 engine. The 5 pinion gears are a great feature, but the #1 reason these gears are better than aftermarket gears is the high quality steel the carriers are made of. (After market 5 pinion planet gears aren't as strong as OEM 4 pinion planet gears.)

Extreme Duty front planet with 5 pinion gears (right side).

. . . . . . These GM 2002 type 5 pinion planet gears are at least 25% stronger than the old type 4 pinion planet gears. . . . . . . . .

You get all of the features of the world famous 700 Raptor transmission plus all of the above features as standard equipment on the 700 Mega Raptor transmission. Plus a PATC T-shirt and your choice of a transmission cooler or deep factory type pan, if you buy a torque converter with the transmission. All of the above for $2769.00 without the torque converter.

This is what makes the 700R4 transmission so efficient. There's no heavy direct drum that spins at three times the engine speed in first gear, and then comes to a complete stop in second gear, and then speeds back up in high gear (3rd) to engine speed. To me all of this sounds like alot of parasitic drag the 700R4 doesn't have. Couple this with the 2.66 to 1 first gear planet sets coming up in the near future and the titanium input drum coming later that tested to almost 1000 foot pounds of torque, and all of this will result in the 700R4 being one of the strongest, light weight and efficient transmissions around.
