		Accu-Speed: The JET Accu-Speed for 93-up Dodge, Ford, GM, Jeep and Toyota trucks and SUV’s modifies the vehicle speed sensor output readings to correct the speedometer after making gear ratio or tire size changes. Shift points in automatic transmissions are also corrected. The Accu-Speed connects to the transmission output speed sensor and is calibrated with the turn of a switch. The JET* Accu-Speed is only available for automatic transmissions.

		Speed Control Unit 2000: The JET SCU-2000 (Speed Control Unit) modifies the vehicle speed sensor output readings to correct your speedometer and odometer after making gear ratio or tire size changes. Shift points in automatic transmissions are also corrected. As a bonus the SCU-2000 also removes the top speed limiter! The unit installs with simple plug-in connectors to the transmission output speed connector and is easily calibrated by adjusting the dials. Available for 1996-Current GM Trucks and some 1994-2002 GM Passenger Cars. The SCU-2000 is only available for automatic transmissions.

		Billet Powr-Servo: Some automatic transmissions use a servo assembly to initiate a shift by applying a clutch band. The JET Billet Powr-Servo is precision machined to provide a larger apply area which applies the band with greater force. The result is a greatly improved shift quality and less transmission slippage under hard throttle or heavy towing. 700 R-4 and 4L60-E servos install on side of transmission case without removal of pan and with minimal fluid loss. Other applications may require removal of pan and other components to install. Professional installation is advised. The Billet 4th Gear Powr-Servo is available for 700 R-4, 4L60-E and 4L65-E transmissions. The 4th gear servo applies the band that holds overdrive with more force for improved towing and high speed performance. Can be installed in conjunction with the 700 R-4, 4L60-E or 4L65-E Billet Powr-Servo to improve transmission shifting in all 4 gears.

		Power Shift: Plug the JET Power Shift into your automatic transmission wiring harness and you can choose from four different shift firmness settings--Stock, Stage I (for around town driving), Stage II (with a more aggressive feel), and Race. The Power Shift is compatible with use with the JET Powr-Servo Kits for an extremely firm shift.

		JET Skip Shift Eliminator: The JET Skip Shift Eliminator bypasses the computer aided gear selector feature on the newer GM 6 speed transmissions. The CAGS feature causes the unwanted 1st to 4th gear shift. Installation is a simple plug in and the unit is OBD-2 compatible.


		700 R-4 Lockup Delay Module: The JET 700 R-4 Lockup Delay Module prevents converter lockup until 4th gear, eliminating unwanted converter locking and unlocking in 2nd and 3rd gear. Reduces wear on converter clutch and prevents engine lugging due to premature lockup. Simple, plug in installation.

		700 R-4 TV Cable Brackets: 700R-4 transmission are controlled by an adjustable throttle valve (TV) cable that attaches to the carburetor or injector linkage with a special bracket. The cable regulates internal line pressure, shift points and downshifts, so proper installation and adjustment is critical. JET offers TV brackets for most popular carburetors for 700R-4 conversions. Designed to work with GM factory cables.
