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 a lot of parasitic drag the 700R4 doesn't have. Couple this with the 2.84 to 1 first gear planet set 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 10 or 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 runs from free to $165.00 after freight discount 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 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 with-stand way over 600 foot pounds of torque. Made with new input drums and 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 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.
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, 4L60E and 4L65E 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 4L65E 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.)

√ #9. Hayden transmission coolers. 12 X 7 1/2 X 3/4. Cost $45.00 - - - 15 1/2 X 10 X 3/4. Cost $55.00 - - - Needed for any type high performance / heavy duty use. Recommended for stall speeds of 2,000 RPM or higher and towing.
Transmission Cooling: You must have a transmission cooler in your radiator regardless of what someone has told you for the transmission to last. Auxiliary coolers are just that, in addition to. Water cools 32 times better (faster) than air always, period. The transmission fluid comes directly from the torque converter at a much higher temperature than the water in your radiator and is cooled to the water temperature fast. Then it goes to the auxiliary cooler to be cooled far below the water temperature. If you don't need a cooler in your radiator why does GM spend all that money doing so? If you wanted to cool a red hot piece of steel fast would you stick it in water or air, see the point. For the best cooling you need both water and air cooling for the transmission to be cooler than the motor. |

Extreme Duty Metal Impregnated Carbon Fiber Flex Band √ #11CF. Alto Carbon Fiber 700R4 / 4L60E band made exclusively for PATC to our specifications. No one else has or sells this band. This band is an Alto Carbonite PowerBand but in the standard width. It has the heavy duty thick anchors on both ends. Alto is pleased to announce a new Carbon lined 2-4 band for the GM 700R4 family of transmissions. This new band will retro back to the 1982 700R4 and will also fit the 2005 4L65E and all the transmissions in between. Both of the band anchors have been hardened to ensure durability. The Carbon lining is up to the task of any application that these transmissions are used for. This is a direct replacement band, for best performance and to prevent a "Comeback" from 2-4 band failure. (We recommend this band over the #11 band because the wide band must be used with a new reverse input drum otherwise the band will burn on the two outer edges.) Cost $23.00, 5 or more $19.00 each

#18A. For light vehicles under 3200 pounds with 3.73 and lower gear ratios. #18B. For medium weight vehicles such as Camaro with 3.42 to 3.73 ratios. #18C. For heavy vehicles with 3.08 to 3.42 ratios. Use this one with taller than stock tires, and lower than stock gear ratios. Vehicles with a 200-4R, 700-R4 or 4L60E transmission can experience 1-2 light throttle abrupt or "bang" shifts, especially when using the Corvette or larger 2nd apply servo pistons. The current industry solution is to make the servo piston apply diameter smaller. This, however, limits the 2-4 band life. This shift problem commonly occurs when the accumulator valve is too large for the application, resulting in too much pressure on the 2-4 band. This valve train has 7 different OEM size variations: B, A, N, M, L, K, and F. They range from the largest valve diameter giving the firmest shift (B) to the smallest valve diameter giving the softest shift (F), respectively. The size variations are clearly stamped with the letter on the aluminum sleeve. Most vehicles, depending upon the transmission / engine combination, can use either the M, L, or K version. However, these are not available unless scavenged from other valve bodies. Each kit contains three springs of varying spring rates. Cost $42.00 |

Accumulator Valve Train Assembly
|
![]() |
A worn 3-4 relay / 4-3 sequence valve body bore can cause a no 4th gear situation in a 700R4 or 4L60E. Due to the constant valve oscillation, wear occurs at the 4th accumulator circuit. This can lower 4th gear pressure by as much as 20-25 psi, resulting in lower servo apply pressure or no 4th gear. Leakage also occurs at the end plug, due to valve hammering. This allows 4th signal oil loss which can result in a no 4th gear situation. Sonnax now offers two oversized 3-4 relay and 4-3 sequence valve kits for the 700R4 and 4L60E. Reamer required for these two valves.

#19X.
700R4 Extreme Duty rear planet 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. 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 are not as strong as OEM 4 pinion planet gears.) Cost $310.00. ON SALE FOR A LIMITED TIME, Cost $179.00
#19XX.

700R4 / 4L60E "Power Gear"
"The Next Big Thing". PATC has developed a new 6 pinion planet gear set for 700R4 / 4L60E transmissions. This will be the biggest thing in 700R4 advancements in years. These will have a 2.84 to 1 first gear, 1.56 to 1 second gear, 1 to 1 third gear and .70 to 1 overdrive ratio. This close ratio 700R4 gear set will have a 11.72% less RPM drop between 1st and 2nd than the wide (stock) ratio gear set. In other words the close ratio gear set will only have 88.28% as much RPM drop as the wide ratio gear set. This is what people have been asking for, for years. These will work on any 4L60E type transmission without a gear ratio error code, if the PCM is modified. The carrier is made from E4340 billet steel and the pinion gears are 9310 steel. With the billet sun gear made from 9310M steel. This gear set is used to reduce torque multiplication / rotating speed in the transmission in first gear. This improves track applications that overpower the rear tires upon launch. This is common with numerically high final drive ratios. Now you will have a choice between the wide ratio or the new close ratio gear sets. In first gear this close ratio gear set has a 7.2% numerically lower final drive ratio. It has been reported that the 2.84 gear set could lower your quarter mile time as much as 4/10 of a second over the 3.06 gear set. This gear set has been in research and development for over one year. You might ask why 6 pinion gears. The answer is because high horse power motors can eat the small needle bearings up in the pinion gears. The solution is to spread the load over 50% more needle bearings and at the same time building the planet gear set out of a higher grade steel. The first 50 are in production now and the approximate release date is May 2009. We have finished the testing in our test truck with the following findings. The gear noise in manual low is reduced by at least 50% compared to a stock OEM planet gear and at full throttle there was no noticeable power drop on the 1st to 2nd shift. Testing will begin later this week in an 1100 horse power C5 Corvette. The car runs 9.56 seconds now. Nothing will be changed but the front planet gear then tested to see the difference. Testing should be completed by 6-1-2009. Patent Pending
Here are the test results from the weekend of May 30-31, 2009. Both where run for the base time then nothing was changed but the front six pinion planet gear then retested to determine the time difference.
The first car is a C5 Corvette with an 1100 horse power blower motor. The best time with the factory planet gear was 9.56 and the time with the new 2.84 six pinion planet gear was 9.25. This is a whopping 3/10 of a second faster in the quarter mile. The time would have been even better if the 3-4 clutch wouldn't have been slipping. Perhaps as much as 1/2 second better then the factory gear ratio.
The second test was with a 460 horse power all-wheel-drive Chevy Cyclone. The best time with the factory planet gear was 13.10 and the time with the new 2.84 six pinion planet gear was 12.90. This is a whopping 2/10 of a second faster in the quarter mile. There was 300 to 400 less RPM drop on the 1-2 shift with the new gear ratio. This truck didn't have a problem with tire spin on take off because it has all -wheel-drive. The 2/10 of a second was picked up on gear ratio change only, not on take off.
Update 6-3-2009: Three more reports have come in with 3/10 of a second or more off of their E. T..
| Transmission Ratios | 1st to 2nd Ratio Drop | 1st Gear | 2nd Gear | 3rd Gear | 4th Gear OD |
| Turbo 350 | 1 | 2.52 | 1.52 | 1 | N/A |
| Turbo 400 | 1 | 2.48 | 1.48 | 1 | N/A |
| 200- 4R | 1.17 | 2.74 | 1.57 | 1 | 0.67 |
| 700R4 / 4L60E with PATC close ratio gear set. Low geared 1st with 11.72% less 1st to 2nd RPM drop than the wide ratio gear set. This is the same ratio as a 4R70W transmission. | 1.28 | 2.84 | 1.56 | 1 | 0.70 |
| 700R4 / 4L60E | 1.43 | 3.06 | 1.63 | 1 | 0.70 |

#20. 700R4 full throttle 3-4 up-shift sleeve. Now you can have a full throttle 3-4 shift. At 80 MPH it takes 90% throttle to make a 4-3 downshift. Can be installed without removing the valve body. The Up-shift Sleeve also eliminates part throttle 4-3 downshift for less gear searching. This is an extra option on the 700 Raptor. Not recommended for motors over 250 horse power. Cost $58.00 |

#20S. This is the replacement for a worn throttle valve. This is the larger one, code 94. Poor line rise or no detent downshifts can be common complaints in vehicles with a 700-R4 transmission. The steel throttle valve plunger continuously reciprocates within the aluminum throttle valve plunger sleeve, thus wearing the sleeve. This wear allows throttle valve feed oil to leak past the plunger and exhaust, resulting in poor line rise and problematic downshifts. In addition, the OEM spring is weak and can result in low line rise, insufficient throttle pressure and, ultimately, 3-4 clutch failure. Cost $49.00 |

#20T (700R4 & non-PWM 4L60E) #20E (4L60E PWM units). These hardened steel converter clutch apply valves will eliminate bore cross leakage with a Teflon seal. Vehicles with a 700-R4 or 4L60-E transmission have numerous converter overheat and lock-up complaints related to valve bore wear. These include no lock-up or lock-up immediately after 2nd gear when fluid warms up. Frequently the solenoid will have no control over the valves position. These complaints are usually created by excessive pump bore to valve clearance. Often converter feed oil will leak past the OEM spool, which added together with orificed signal oil, will be more than the solenoid can exhaust. This may completely stroke the valve into the lock-up position and create a no power or no brake cancel condition. Oil cross leaks may float the valve into a midway position and restrict cooler flow, which burns up the converter. Cost $22.00 |

#30CB. Torlon Check Ball, .250", 10 per bag. The new check balls (.250") are made out of tough wear- resistant imidized plastic. The imidized plastic balls seal better than steel balls because they conform to the separator plate ball seats. Steel check balls are hard and heavy, wearing separator plate ball seats from the repeated high impact of the ball on the seat. Elastomer or rubber check balls seal well. However, the elastomer material wears, reducing the size of the ball. Fits 700R4, 4L60E, 200-4R, TH400 and 4L80E transmissions. Sold 10 per bag. Cost $7.00 |
