The T56, T56 Magnum, and TR6060 transmissions come equipped with 3 electronic connections that control the vehicle speedometer output, reverse lock out, and reverse lights.  If you are using the T56 Magnum in conjunction with a GM connect and cruise package or utilizing an electronic speedometer from companies such as: Classic Instruments, Auto Meter, or Dakota Digital you will will be able to program the outputs to the needed pulse count as well as control the parameters of the reverse lock out all from the Bluetooth enabled smart phone app.

The All-in-One harness solution for the T56 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 our 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.

Installation Instructions

The All-in-One harness eliminates the need for any additional equipment to operate the reverse lock out or generate the correct speedometer signals coming from your T56. This All-in-One harness solution is the perfect finishing touch for any T56 conversion, and the only harness you will ever need. Prior to the development of the All-in-One harness you would need up to 5 separate parts to perform all the same functions wrapped up in this one harness solution. Getting the correct speed sensor output and operating the reverse lock out are typically the most frustrating and confusing. The more technology we incorporate into our hot rods these days sometimes requires specific input signals to allow everything to function correctly. There may be scenarios where you are using a speedometer that requires one signal and an ECM that requires a completely different signal. With the 2 speed outputs that are available in the All-in-One harness you can independently control the output of each one further eliminating any need for additional equipment and connections.

The reverse lock out on the T56 is another commonly misunderstood feature. The reverse lock out is a solenoid controlled pin, that uses a spring to exert pressure against the shift rail, to help prevent an accidental shift into reverse when going into 5th gear. It doesn’t prohibit reverse engagement, it only makes it difficult to shift into reverse when it is not getting a power signal. Once power is applied, the solenoid pulls the pin back allowing reverse engagement with minimal effort. The OE’s control this feature using a speed setting to dictate when the pin is pulled rather than a momentary on/off signal. We’ve incorporated that same speed setting feature into the All-in-One harness to give you better control over when the lock out is triggered.

The T56 All-in-One Harness utilizes a small, built in, epoxy sealed box that will control each of the 3 functions with power and grounding for each function through a switched +12v 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 0-3 MPH) This eliminates the need for a separate lock out control box which is currently the only option to activate the reverse lock out correctly. It is common for most folks to just simply connect their lock out solenoid to a momentary on/off switch such as the brake light switch to activate. This method will get the job done, but can over work the solenoid, and over time shorten its life span.

For your electronic speedometer, the harness is equipped with 2 speed sensor outputs; the speed sensor outputs generate a square wave signal that goes from about -5 to roughly +5 volts, varying in frequency as the speed changes. But, you say, my ECM input needs a positive only signal. No problem! The output will automatically shift and give you 0 to +10 volts. The 2 speed sensor outputs are completely independent and can be calibrated separately with any pulse count and ratio you want. So, these two outputs should pretty much be able to drive any common speedometer, cruise control, or ECM. This will give you much greater flexibility in the components you are able to use and requires less time wiring everything up.

The reverse lights are powered by a single output wire connected to the positive side of your reverse lights; grounding of those lights should be local to the bulb socket. There is no easier solution for setting up your T56 transmission! T56 Reverse Lock Out Module Vehicle Speed Sensor with Dual Output, pre-set as GM 40 pulse output on one and 16 pulse output on the other. This function can be adjusted with your iOS or Android device. Includes wiring for reverse lights, reverse lock-out and vehicle speed sensor.

Ram Clutches Pro Street clutch is a great choice for high performance cars!  This is a twin disc clutch with steel flywheel and organic material.

Pedal feel is excellent with this clutch thanks to Ram’s billet aluminum cover plate design.

This fits Ford small block engines with external balancing with 50 oz. weight.  Fits transmissions with 1-1/8″ diameter 26 spline input shaft including the T56 Magnum and TKX.

RAM started with a clean sheet of paper in designing the Pro Street Dual Disc clutch system. The heart of this design is the billet aluminum cover, which is optimized for pedal effort and holding power to combine for our most driveable street dual disc system. The features listed below help the Pro Street Dual to surpass other clutch market designs, such as:Pro Street Dual Disc

Optimized pressure plate design – by manufacturing this cover in house, we are able to control the static pressure, release length, and lever position of the clutch and dial these in for the best possible driving experience, whether on the street or on the track.

Shift it higher without worrying about getting locked out – you will never have to worry about stuck down pedals due to high RPM shifting. The Pro Street dual handles high RPM with ease!

Optimized engagement length – If you have ever driven cars that feel like they have an on/off switch for a clutch pedal, you know how uncomfortable that can be. The Pro Street dual is easy to modulate and make a smooth engagement/takeoff.

Size – the larger the diameter the more the holding power the clutch system will have. The 10.5 pressure plate has 2400 pounds of clamp pressure, where competitor’s 9.5 assemblies typically have 1800 pounds of clamping force. The larger clutch diameter will also further enhance heat dissipation over the smaller units. Stock pedal effort is maintained with the Pro Street Dual Disc.

Precision machined billet flywheel provides a stable mounting platform. Each unit is set up on the flywheel before shipping to insure proper release once the clutch is installed. A specification card is provided with each unit to aid you in setting up the clutch properly in the car.

Precision balance on the flywheel insures proper balance and vibration free driving. Match balancing available by special order.

Strap driven floater plate system assures quiet, no-rattle operation.

Utilization of a sprung hub top disc to ease stress on the driveline during initial engagement. Dual solid hub designs are aggressive and more susceptible to gear noise in the transmission.
