#45. 700R4 / 4L60E Extreme Duty Torque Drive Package. You get a hardened input shaft and drum assembly plus a hardened reaction shell with 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. Call toll free 1-888-2012066 for your special price.
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. Cost $298.00.

# C480. 4L80E in C4 Corvette Adapter (1984 - 1996). Swap your 700R4 / 4L60E transmission to the much stronger 4L80E transmission with our new double strength case hardened output shaft and adapter kit. At this time we have in development an adapter kit for the C4 Corvette to replace your 700R4 / 4L60E transmission with the much stronger 4L80E transmission. This 4L80E transmission will be the same length as your 700R4 / 4L60E transmission making it possible to reuse your existing 27 spline driveshaft and C-beam. All that needs to be changed on the 4L80E transmission is the tail housing and output shaft. The full manual shift model works without a computer. This tail housing is made of 6061T6 aircraft aluminum. Cost $699.00 |
||
|
There may be other uses for this shaft. Replace any 700R4 / 4L60E transmission with a 4L80E of the same length. Coming soon 700R4 / 4L60E to TH400 and T-56 to 4L80E adapter kits. |

#68. Install a mechanical tachograph or operate a mechanical speedometer on a vehicle equipped with an electronic speedometer signal (sensor). You can do it -- quickly and easily -- at a cost far below that of buying and installing drive gears in the transmission.

Cable X lets you use popular, low cost mechanical tachographs such as Abbott, Argo, Sangamo, Servis Recorder and Veeder-Root, and mechanical speedometers such as Autometer, Clark Brothers, Datcon, Stewart Warner and Teleflex. It operates at accurate speeds -plus or minus 2%- on the most common OEM electronic speed signals, and is as easy to install as any electronic tachograph.
You save hours of downtime installing gears into the transmission, and you don't have to mess with troublesome, expensive and long cables. Cost $319.00
The following is the price for a Cable X requiring a Ford "snap-on" fitting: $369.00

#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 $289.00
#19XX. 700R4
Extreme Duty front
planet with 5 pinion gears (right
side). Due
to a change in the bearing design by GM, we now sell the front 5 pinion planet
gear with the Torque Master kit included.
Cost $189.00

#22X. Alto 200-4R oversize intermediate bands (Wedge Band). These bands are over 3/8 of an inch wider than a stock band. A full 2 1/4 inches. This is a whopping 20% more holding power. The anchor area is thicker than the stock band. Now this band is made with the new wedge design on the apply pin end to prevent the pin from breaking through the metal, see below. These PowerBands are available in Red Eagle for $28.00 and Kevlar for $38.00.

#44X. 700R4 / 4L60E Extreme Duty reaction carrier shaft. Same as the above but better. This is our own brand (Torque Master Package). Better because it has the Beast shell instead of the GM shell. We decided to make this shaft because the GM shaft is almost impossible to get. This was the last part needed making it possible to build the entire transmission without the use of thrust washers. 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. Cost $150.00. Sold without the shell for $116.00
