Steeda speedometer plugs cover up the mechanical speedometer gear access hole in the new TKO 500 and TKO 600 transmissions, so they can be used on 1999 and later Mustangs with electronic speedometer pickups. The new TKO transmissions are equipped with dual speedometer pickups to work with either electronic or mechanical speedometer pickups. A plug is required to cover the mechanical access hole if it is not being used. The plugs also fit most common Ford transmissions, such as the T-5 and T-45, and are designed for use on race cars without speedometers.

Bowler Performance All-in-One transmission wiring harnesses for the Tremec T-56 Magnum transmission comes equipped with all the connections pre-wired into one harness for a simple installation and ease of use. The small epoxy sealed controller is mounted to the VSS output using the existing bolt, and once the unit is powered up, you will be able to connect via Bluetooth to your Apple or Android smartphone using Bowler's free app. The app will give you the ability to customize the input and output settings for each feature to ensure proper operation in your vehicle. The perfect finishing touch for any Tremec T-56 Magnum conversion, Bowler's All-in-One harnesses eliminate the need for any additional equipment to operate the reverse lock out or generate the correct speedometer signals coming from your Tremec T-56 Magnum. Previously, you would have needed up to five separate parts to perform all the same functions wrapped one of these harnesses. The more technology we incorporate into our hot rods sometimes requires specific input signals to allow everything to function correctly. With the two speed outputs available in these harnesses, you can independently control the output of each one further eliminating any need for additional equipment and connections. Regarding the reverse lockout, Bowler has incorporated the same speed setting feature as the OEs into the All-in-One harnesses, giving you better control over when the lock out is triggered. Bowler's All-in-One harnesses give you much greater flexibility in the components you are able to use and require less time wiring everything up, providing an easier solution for setting up your Tremec T-56 Magnum transmission. Choose the harness version designed for your specific transmission make. Additional notes: * Harnesses utilize a small, built in, epoxy sealed box that will control each of the three functions with power and grounding for each function through a switched +12 V circuit and a wire connected to the negative battery post or engine block. * Control of the reverse lockout solenoid is based on a user defined speed setting (default is set at locked above 4 mph and unlocked at 0 to 3 mph), eliminating the need for a separate lock-out control box. * For your electronic speedometer, the harness is equipped with two speed sensor outputs; the speed sensor outputs generate a square wave signal that goes from about -5 to roughly +5 V, varying in frequency as the speed changes. * Output will automatically shift and give you 0 to +10 volts for EMC input needing positive only signal. * The two speed sensor outputs are completely independent and can be calibrated separately with any pulse count and ratio you want, and are able to drive any common speedometer, cruise control, or ECM. * Tremec T-56 Magnum reverse lock-out module VSS with dual output, pre-set as GM 40-pulse output on one and 16-pulse output on the other and can be adjusted with your iOS or Android device. * Includes wiring for reverse lights, reverse lock-out, and vehicle speed sensor.

With all the most important content from the original Magnum, Tremec Magnum XL 6-speed transmissions retain brute strength and sophistication, but eliminate multiple shifter locations and dual speedo outputs. Each XL extended length tail section provides a rigid direct-mount shifter designed to eliminate the semi-remote shifter found in many popular late-model applications, delivering vastly improved performance and lightning quick shifts. Tremec Magnum XL transmissions not only offer shift performance and extended length, but they are also rated at 700 lb.-ft. of torque, support 7,800 rpm shifts, and are available in two gear ratio configurations. The Magnum XL was designed specifically to replace the OEM 5- or 6-speed transmission where performance improvements are desired. Simplifying the swap, they include an SFI-approved steel bellhousing, crossmember, trans mount, isolated shifter, and shift ball. They also reuse the OEM hydraulic clutch release system. Select the ideal gear ratio for your build. Features: * Extended- length (XL) extension housing * Shifter location that mimics several late-model applications * Reverse inhibitor solenoid * Electronic speedometer output * Fluid fill and drain ports * Common "T-56" style bolt pattern * Mounted pad for OEM-style hydraulic slave or aftermarket guide tube * Standard Magnum clutch fork exit window * Unique isolator-style shifter for reduced noise, vibration, and harshness (NVH) * Reverse light switch

TCI StreetFighter transmissions are durable enough to withstand the rigors of even the toughest street machines. Equipped with a manual/automatic valve body, most units allow you to manually shift the vehicle into each gear change or, by placing it in the drive position, remain fully automatic. In either mode, you get a race track shift that bangs through the gears and shaves time off of your ETs. When you use the manual gear selection feature, the StreetFighters upshift and downshift right when you move the lever, with no lag or governor override. When you select the normal drive position, they retain positive automatic shifts for the ease of driving you look for in an automatic transmission.
