Our shifting systems are practically universal. A lot of cars that have automatic , manual, or sequential transmissions are already cable shifted. If the transmission in your vehicle is cable shifted, our paddle shifter kits are able to be used to control the transmission! See FAQ specific to your transmission type below.

For a brief explanation of how our system works, please watch our demonstration video. They will answer most questions on how our shifters operate.

Manual Transmissions

Automatic Transmissions

Use the following list as a check off list: Is your transmission automatic? manual? or sequential? Pick a kit accordingly (see Shifter Kits section)in our store, then see below for the supporting hardware/equipment required to run the automatic, manual, or sequential kit.
If you have a stock oem airbag or a 9 bolt wheel, you WILL need to check our store in Paddle Upgrades. The paddles that come with our shifter kits only covers 5 or 6 bolt aftermarket wheels. The 5 and 6 bolt steering wheels also have upgraded polished billet paddles available in bent or flat. (Bent are for flat steering wheels and flat paddles are for wheels with a deep dish)
A gear indicator is a MUST in order to keep track of the current gear. You may have a standalone gear indicator on your end, however our systems are only compatible with our own gear indicators! You will not need a gear indicator if you choose to go with our push button gear selectors.
We have bump shifters that act as a sequential shifter and push button gear selectors that light up in every gear. See Paddle Alternatives in the store.
The control box measures: 8.9” x 5.6” x 5” for automatic and sequential shifters and 10.25” x 10” x 4.4” for the manual shifters. The box can be mounted in virtually any location ranging from under the seat, in the trunk, anywhere that space allows for. However, keep the box out of extreme heat (i.e. next to the exhaust or engine). Our shifter kits do not contain cables for this reason ($50-75 ordered from provided retailer) because the distance from the transmission to the control box varies depending on where you choose to mount the box! See our Specifications section for more measurements and general information.
No, however with our clutch sensor option, they do activate shifts.

Most cable shifted transmissions are able to be shifted with our systems without additional hardware except the spring load for transitional shifts (See Hardware in the store). Any other transmissions, such as the T56, will require additional hardware as they are not cable shifted. Please see a list of hardware supported transmissions in our store under the Hardware section if your transmission is NOT cable shifted!

MasterShift™ Spring Load (recommended)
This spring load hardware mounts to the end of the push pull cable used by the MasterShift system, and attaches to the transmission interaction hardware. Typical shift movements require 3 distinct movements: first to pull the transmission out of gear, the second to swing over in natural (cross gate), and the third to push the transmission back into gear. These three motions each require a start and a stop. With the spring load hardware, we can apply a biasing force on the shifter when you are in 2nd gear or 4th gear, that will automatically cause a swing across the cross gate when the MasterShift pulls out of 2nd gear towards 3rd. This allows the MasterShift to do one QUICK motion straight from 2nd gear towards 3rd, and the transition across the gate is handled by the spring. Thus VERY fast 2nd to 3rd and 4th to 5th shifts.

MasterShift™ Clutch solenoid (recommended)
The clutch lock system consists of a full flow solenoid, block, and relay. The solenoid is controlled by the MasterShift system to enable the driver to simply stab at the clutch to start the shift, and the MasterShift ensures that the clutch is held for the correct amount of time for the shift to complete. This is an advanced safety feature for race applications or for extremely quick shifts.

MasterShift™ Clutch Sensor (recommended)
The MasterShift Clutch Sensor mounts to your clutch pedal to read its motion. In the MasterShift software you can set an exact point for the clutch disengagement. This ensures that a shift only starts when the clutch is to a point where it is fully disengaged. This helps to eliminate any timing issues with trying to clutch and paddle at the same time. Now you can simply pull the paddle, and press the clutch, and the shift will start right when the clutch pedal reaches a point where the clutch is disengaged.

The high torque motor is for vehicles with high torque application. Any high performing vehicle will need an upgraded motor to withstand shifts.

1. Delayed Shifting (Clutch Sensor)
Pressing the clutch pedal is necessary for the shift to happen, so the Manual Shifter waits with the shift until the clutch pedal is pressed. This feature can be used for delayed shifting. For example, you can drive into a curve, anticipating that you will have to shift down into second gear. You press the paddles the required number of times, and no shifting will occur until you press the clutch pedal. If you don’t press the clutch pedal for a configurable amount of time, the Manual Shifter cancels the shift.

2. Neutral Safety
When the Neutral Safety feature is enabled, a safety push-button, or safety delay must be pressed every time the driver wants to shift from first gear into neutral. The purpose of this feature is to prevent accidental shifts into neutral gear during normal driving. Multiple presses of the downshift button or paddle (without pressing the neutral safety button) are now safeguarded to not shift into neutral.

3. Reverse Safety
When the Reverse Safety feature is enabled, the safety switch, or safety delay must be pressed every time the driver wants to shift into reverse gear. The purpose of this feature is to prevent accidental shifts into reverse gear while the car is moving forward. It serves a similar purpose as the mechanical locks many H-pattern transmissions have on their shift sticks.

4. Clutch Safety (Clutch Hold)
The Clutch Safety feature makes sure the Manual Shifter does not attempt to shift while the clutch pedal is not pressed. This is required for all standard manual H-pattern transmissions, and is not configurable. Required for this feature is a switch that is closed or opened when the clutch pedal is pressed. It may also be possible to use an inline hydraulic pressure switch

5. Speed Safety
The Speed Safety feature works similar to a typical park/reverse protection in automatic transmissions: it prevents the driver from shifting into reverse when the car is moving (which is detected by a speed above 1 mph). Required for this feature is a speed sensor pulse. This may be a raw speed sensor pulse, or a speedometer pulse that is usually sent from the engine or powertrain control module to the speedometer.

6. OneWire™
The paddle shifter with OneWire board is to be used on vehicles with aftermarket steering wheels that have a horn wire that runs down the steering column of their vehicle. The OneWire system eliminates the need to run wires down your steering column and thus makes installation easy and painless. Steering columns such as Ididit and Flaming River are also supported as long as they have a horn wire.

Most automatic transmissions are cable shifted, meaning a cable is mounted to the shifter lever and thus the detent levers on the transmissions are controlled as such. Therefore, most automatic transmissions are compatible!
The MasterShift™ Auto Shifters are commonly put in such transmissions without any issues: 700R4, Turbo 400, Ford AOD, GM-4L60 and 4L60E, GM4L80, just to name a few.

1. Overdrive Control
In the OneWire board inside the paddle assembly as well as at the MasterShift™ Auto Shifter unit is a switch input available for control of an overdrive unit. Both work as toggle inputs: pressing a button connected to either input changes the state of the overdrive output (switches it off if it was on, or switches it on if it was off). The switch input of the one-wire board inside the paddle assembly can be conveniently wired to a push-button switch mounted to the steering wheel. It is also possible to include the overdrive engagement into the shift sequence. This way, the MasterShift™ Auto Shifter makes it possible to use the overdrive as a gear splitter. For example, shifting from 2nd to 3rd position now occurs in two shift commands: the first enables the overdrive, placing the vehicle into something like a “2nd plus overdrive” gear, and the second shift command moves the shift lever to 3rd position and disables the overdrive. Caution: Even when using an overdrive unit with the Auto Shifter, the driver is responsible for operating the overdrive within its specified limits.

2. Overdrive Protection
Some overdrive constructions should not be driven “backwards”, that is with reversed torque, either in reverse gear or whiles the engine is braking the vehicle. The MasterShift™ Auto Shifter provides two safety features that help prevent such situations. a. Automatically Disabling the Overdrive on Downshift b. Automatically Disabling the Overdrive when Braking

3. Neutral Safety
When the Neutral Safety Switch feature is enabled, the shift safety push-button, or safety delay must be used every time the driver wants to shift from a forward gear into neutral. The purpose of this feature is to prevent accidental shifts into neutral gear during normal driving. Multiple presses of the downshift button or paddle (without pressing the shift safety button) are now guaranteed to not shift into neutral. This is especially useful for manual shift automatic transmissions.

4. Brake Safety
The Brake Safety feature prevents shifts into reverse gear or park unless the brake pedal is pressed. This is a standard safety feature for automatic transmissions.

5. Speed Safety
The Speed Safety feature works in the same way as the Brake Safety feature: the driver is not allowed to shift into reverse gear or park when the vehicle speed is above 1 mph. This is also a standard safety feature for automatic transmissions. Required for this feature is a speed sensor pulse. This may be a raw speed sensor pulse, or a speedometer pulse that is usually sent from the engine or powertrain control module to the speedometer.

6. OneWire™
The paddle shifter with OneWire board is to be used on vehicles with aftermarket steering wheels that have a horn wire that runs down the steering column of their vehicle. The OneWire system eliminates the need to run wires down your steering column and thus makes installation easy and painless.

MasterShift™ Push Button Shifter
Allows you to individually select a specific transmission gear by the press of a single button. Go from park straight to drive, or park straight to manual 1st. The push button shifter also acts as a gear indicator as the gears light up, so no additional indication system is needed. The MasterShift™ Push Button Shifter must be used in conjunction with our MasterShift™ Auto Shifter kit. The Push Button Shifters are NOT sold separately as they are merely paddle upgrades, and will not function on their own as intended.

1. Short Shift to Neutral - Some transmissions have their neutral gear between the first and second gears; it can be reached with a shorter shift than normally. The MasterShift™ Sequential Shifter supports such transmissions.

2. Clutchless Shifting - The EMS Control output can be connected to an engine management system ( EMS ), to request a torque reduction before and during the shift movement. Torque reduction can be achieved for example by limiting the fuel supply, changing the ignition timing, or limiting the engine rotation. The Sequential Shifter activates the output a short time before the shift movement, giving the engine time to actually reduce the torque on the transmission, and deactivates it immediately after the shift, so that the engine again supplies full torque.

  • Note: Support with all engine management systems cannot be guaranteed. Most often the engine management system will need to be specially setup to work with the MasterShift. Certain Delphi engine management systems even require an auxiliary pin to be wired to the outside plug.
  • Caution: You will need to setup the pre-shift delay time if you are to use the MasterShift to do clutchless upshifts. Due to variances in motors, transmissions, and driving styles, you may need to spend some time configuring this value to an optimal level. Clutchless shifting cannot be guaranteed to work in all driving conditions and may need to be setup multiple times for variances in wheel types, terrain, and other variables. A wrong value can lead to transmission damage over time

3. Neutral Safety - The purpose of this feature is to prevent accidental shifts into neutral gear during normal driving. Multiple presses of the downshift button or paddle (without pressing the shift safety button) are now safeguarded from shifting into neutral. (This works a bit differently with transmissions that have their neutral gear between the first and second gear and require a special short shift for a shift into neutral.

4. Clutch Safety - When the clutch safety feature is enabled, the driver is not allowed to shift from neutral into first gear without pressing the clutch, and the clutch is also required for all downshifts. The purpose of this feature is to prevent shift attempts in situations when normally the clutch pedal should be pressed.

5. Reverse Safety - Reverse safety has two different modes of operation, depending on your transmission:

  • Transmissions without a reverse gear in the normal shift lever shift sequence (Mendeola): The MasterShift™ Sequential Shifter will not attempt any shift movements while the transmission is in reverse gear, as indicated by a closed reverse gear switch.
  • Transmissions with a reverse gear in the normal shift lever shift sequence (Albins, Fortin): When the reverse safety switch is enabled, the MasterShift™ Sequential Shifter requires that the shift safety push-button, or shift safety delay, is used when shifting into reverse gear.
