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.

700R4 Transmission - Level Three |
This transmission comes with a high performance Superior intermediate billet servo that has 35% more holding power than a Corvette servo. It will give a firmer 1-2 and 2-3 shift. It also has a high performance Superior overdrive billet servo with 50% more holding power than the stock overdrive servo. This servo gives a firmer 3-4 shift. This 700R4 has 8 Red Eagle clutches and full thickness Kolene steels in the 3-4 clutch drum. Our 700R4 comes with the Mega Valve and an oversize low / reverse boost valve, these two valve produce higher pressure and firmer shifts. All of our high performance 700R4 transmissions come with a 13 vane high performance / high volume pump. We use an Alto Carbonite PowerBand with thicker hardened anchors that holds in second and overdrive. Also included in the price is a heavy-duty balanced stall converter with furnace brazed fins, a Sonnax carbon fiber clutch and needle bearing for added strength. This torque converter can be ordered with stall speeds of 1800, 2000, 2300, 2600 or 2800 RPM (#2). Some of the other features are a 30 spline input shaft, "The Beast" reaction shell, special Transgo separator plate if needed, elevated pressure regulator spring, extra wide sun gear bushing, extra wide rear stator support bushing, performance 1-2 accumulator spring, high output pump slide spring, special intermediate servo release check valve, Corvette governor if needed and a 29 element heavy-duty Borg Warner forward input sprag. Also included in this package deal is a throttle valve cable, dipstick and tube, and an automatic converter lock-up switch. Compare all of these features with any other 700R4 on the market. Why pay this much or more without getting all of the good parts? Over-all this is the best 700R4 on the market at the best price. I have one in my one ton Suburban with 463 cubic inches and 455 foot pounds of torque. I pull a 5,500 pound trailer in overdrive all the time. The transmission has been in use for 10 years now with no problems. The 700R4 has a 3.06 ratio in first gear, which is 20% lower than most transmissions. The 30% overdrive will give a 30 to 40% increase in gas mileage on the road over a 3 speed transmission. This transmission is for any type high performance / heavy duty use up to 600 horse power / 450 torque (600 with Raptor Drive package) using pump gasoline. See ratings chart below. Add torque converter and Raptor Drive upgrades if needed.
The 700 Raptor can be yours for the sum of $2295.00, for all two wheel drives including Corvette. This price includes the core charge. You don't need a trade-in. Update your ride to the best 700R4 overdrive on the market. The freight charge is free to $140.00 in most cases. Can be ordered for 4WD for an extra charge of $50.00. Add $50.00 for Corvette case with aluminum bolt on dust cover type case. Convert your 350 or 400 4WD transmission to a 700 Raptor (May require a special output shaft).
The 700 Raptor transmission is built by Wayne McGee. He is a master transmission builder who has rebuilt over 4,600 of these transmissions. If you need the best, you have arrived. See # 4322 below. On 7-17-2002 we installed a 700 Raptor in a 1989 Suburban that drove 3,000 miles to have it installed.

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 Raptor 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 using pump gasoline, 4WD, towing, street rods, drag racing, big block, one tons and others. See ratings chart below.

700R4 / Early 4L60E Extreme Duty Raptor Drive Package. You get a hardened 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. Made with new input drums and hardened shafts. Starting with a high grade of steel this shaft is hardened by electric induction. This shaft is 57% harder than a standard OE shaft. Comes with the Sonnax Input Drum Support Ring installed. Fits late 1987 up.
For farther information on these parts please call toll free, 1-888-2012066. We use these parts in our level four 700 Mega Raptor and 700-E Mega Raptor transmissions.

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 (19X and 19XX) 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. (After market 5 pinion planet gears are not a strong as OEM 4 pinion planet gears.)

Vigilante Torque Converters
The introduction of lock-up torque converters from the OEM manufacturers in 1979 created a challenge for the high performance torque converter industry to develop, design and manufacture this type of torque converter. Benefits of the lock-up torque are less heat in the transmission and better fuel efficiency. Precision Industries designed the first 9.5 & 10.5-inch lock-up torque converter in 1992.
Precision Industries starts the production of these Chevy torque converters with a 98 pound piece of billet steel that we machine in our CNC equipment ending up with a one piece front cover weighing 12 pounds depending on what torque converter series we are building. The billet front cover is one of many reasons that enable Precision Industries to produce a superior product over many of our competitors that try to imitate and copy our product designs. We prefer machining our billet front covers over purchasing forged steel covers due to balancing, excessive weight and density problems that can arise from forgings in torque converters. One of the benefits of our cover is increased clutch surface area by as much as five times over OEM specifications. The increase in clutch surface area along with the unique clutch lining we use ensures that no matter what the application you can retain the lock-up feature for efficiency without durability issues.
