700R4 Constant Pressure Valve Body

Eliminate TV Cable-Induced 700R4 Failures Forever!
The TCI® 700R4 Constant Pressure Valve Body eliminates the threat of a burned up 700R4 forever by eliminating the danger of transmission failure that results from an improperly installed or adjusted TV cable. In the past, the TV cable adjustment on GM 700R4 transmissions required near-expert mechanical ability. Though the TV cable still needs to be used to set part-throttle shift points, line pressure is fixed at a minimum of 200psi -with no chance of burning up transmission clutch plates due to a low line pressure condition.

Torque Converters

Triple Tested Quality

TCI® strives to produce the best torque converters in the industry. Part of the process involves ensuring that each unit is built to spec. Triple TestedRegardless of what category or price level it may fall into, every TCI® torque converter is Triple Tested during assembly.

Once all the prep work on the component parts has been completed, the impeller is welded to the front cover. Immediately following this process, a pair of dial indicators are employed on a rotating table to verify that the impeller body and pump drive hub remain true.

Each unit is then pressurized and subjected to a leak test to confirm the integrity of all the weld seams. Lastly, each unit is computer balanced to reduce annoying and potentially damaging drivetrain vibrations that would occur from an unbalanced torque converter. That's Triple Tested so you can be confident you're getting a torque converter that's ready to roll.

GM Overdrive Transmission Components

Heavy-Duty Flywheels and Flexplates -

TCI® flywheels for GM applications are .035" thicker than stock and the starter ring is welded to both sides of the flywheel for additional strength. Constructed from a high tensile strength material these flywheels resist elongation and cracking. All 168 tooth flywheels have dual GM bolt patterns and are sized for stock 3/8" mounting bolts and can be easily drilled for 7/16" diameter high performance torque converter applications. SFI 29.1 approved.

The Alto Hi-Energy band is an all new, high-strength, stock width band perfect for heavy duty use in applications up to 450 horsepower.

The Alto Red Eagle® Powerband™ and Kevlar® Powerband™ bands are 18% wider than original equipment providing greater torque capacity and more positive 1-2 shifts. The anchor area on these bands is extra thick, heat treated, high-carbon steel construction to eliminate the stretching and breakage associated with stock bands.

Sprags/Roller Clutches

All new, OEM assemblies. Replacing the forward sprag assembly and low-reverse roller clutch is a must when building a high performance 700R4/4L60E. Our forward sprags are 29-elements which makes them an ideal upgrade for earlier 700R4 transmissions that were built with weaker sprags from the factory. Why risk failure by taking a short cut?

373900 TCI Beast 700R4/4L60E Sun ShellNew! 700R4/4L60E/4L65E Beast Sun Shell

Have you ever suddenly lost reverse, 2nd and 4th gears in your street machine? You're not the only one as the OEM sun shell assembly is a known weak point in the 700R4/4L60E. SPX Filtran has retooled the sun shell and improved it by making it thicker and revised the splined area that is prone to fatigue failure in the OEM parts. If you've got a heavy vehicle or an excess of 450 horsepower, the TCI® 373900 Beast sun shell is a cheap insurance policy against failure.
