Chevy 700R4 Transmission – Level 4

  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 twenty 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 planet gears. This transmission is good for any type of heavy duty / performance use up to 700 horsepower / 700 foot pounds of torque 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 withstand way over 600 foot pounds of torque. Made with new input drums and new hardened input 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 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.

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 Hardened 700R4 / 4L60E Drum, Call for Details 1-888-2012066.

Extreme Duty Hardened Reaction Shell and Bearing.

Complaint, splines seem to crack and tear away from the shell due to torque and flex. = Correction, hardened and reinforced shell tested at the same foot pounds of torque as the Raptor Drive drum and shaft.

Complaint, spider cracks on drum at shaft area are caused by hard 1-2 shifts, high torque or heavy vehicle. = Correction, hardened reinforcement drum sleeve / input shaft 57% harder than stock.

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 LS6 engine. Fit 1982 up 700R4, 4L60E and 4L65E type 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 5 pinion 2002 type 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 five pinion reaction carriers were designed for the increased torque load of the 6.0L version of the Gen III V-8, as well as Corvette LS6 engine.

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

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. All of the above for the price shown below without the torque converter. Comes without the torque converter.
