Electronic Transmission Controllers

The COMPUSHIFT Mini Converter Lock-Up Controller is a standalone plug-and-play system designed to control the torque converter clutch lockup and the overdrive on Chrysler A500/42RH, A518/46RH 618/47RH transmissions.  The system uses a miniaturized version of the same control software and electronics as the COMPUSHIFT Sport. The COMPUSHIFT Mini Converter Lock-Up Controller can be programmed by a Smart Device via Bluetooth! A free downloadable App allows the user to adjust and tune for their specific application and diagnose problems should they occur. The easy to read app screens can display current vehicle speed, throttle position, transmission pressure, 4th gear/overdrive activity, torque converter clutch engagement (lockup), and allow for further custom tuning.  The lock-up controller can can drive an electronic speedometer as well.

Unlike other control modules that use vacuum switches or a simple delay timer, the COMPUSHIFT Mini Converter Lock-Up Controller uses throttle position and vehicle speed to optimize overdrive shifting and clutch control.

Installing the COMPUSHIFT Mini Converter Lock-Up Controller is a straightforward operation if you are familiar with working on cars. No special considerations are needed when driving with the COMPUSHIFT Mini.  Properly tuned, your vehicle should have better gas mileage during cruising, and be more responsive to the throttle. The kit ships with all of the parts that should be needed for the installation including COMPUSHIFT Mini Lock-Up Controller with keypad, wiring harness, speed sensor and fittings, hook and loop fasteners, terminals and cable ties.  A throttle position sensor is required and may be purchased separately if needed.   Supported Transmissions

• Chrysler A518
• Chrylser A618

Resources Refer to the COMPUSHIFT Mini Manual for details on how to set up and install the system. You may also refer to Compushift Mini 518 Instructions.

COMPUSHIFT 3 Sport operates automatic shifting, paddle shifting, and torque converter clutch lock-up for a wide variety of transmissions, allowing the owner to customize performance and the driving experience. No laptop is needed to program the COMPUSHIFT 3, but a PC can be connected for system software updates and tuning if desired. The system is delivered with versatile factory-set programming for a wide variety of transmission and engine combinations. Throttle position measurement, needed for proper transmission shift timing and control, can be taken from an existing fuel injection system signal (harness provided), or a throttle position sensor can be used for gasoline carbureted engines or mechanical injection diesels. Dual CAN buses can connect to existing engine management or body control computers. A MAP sensor can be connected for turbocharged applications if needed. The kit includes all of the necessary cable harnesses AND required throttle position sensor (TPS) package. *Kit does NOT include display or control interface. The Compushift 3 contains a Bluetooth wireless radio to allow connection to any Android or IOS phone or tablet. Supported Transmissions

• GM 4L80E / GM4L85E
• Late GM 4L60E / GM4L65E
• GM 4L60E transaxle (Corvette)
• GM 4L70E

The AccuLink TPS system is the combination of a sensor, brackets, and linkage that bolts directly to most of the popular carburetors. This system replaces the traditional cable-actuated throttle position sensor. Carburetor and cables not included. Features

• The AccuLink Throttle Position Sensor (TPS) kit detects the degree of throttle input on a non-EFI engine and provides this information to your COMPUSHIFT system.
• AccuLink Throttle Position Sensor fits all Edelbrock AFB, Holley, and Rochester carburetors.
• The sensor is a spring-loaded, fully sealed rotary position potentiometer specifically designed for automotive use.
• All linkages, brackets, screws and nuts are stainless steel for corrosion resistance and longer life.
• The linkage and brackets are laser-cut for extreme accuracy.
• The sensor mounts directly to the carburetor and connects via a metal linkage. This eliminates installation and calibration difficulties that can occur with cable-driven

All new COMPUSHIFT kits include the AccuLink TPS for no additional charge unless otherwise specified. Because the cable system and the AccuLink TPS use the same basic sensor and compatible wiring harnesses, we also offer an inexpensive upgrade available to existing customers who own the cable system. Customers who are using a Lokar cable, may wish to purchase the AccuLink Bracket for Lokar Throttle Cables. Suitable existing installations that use the Cable-operated Throttle Position Sensor can be upgraded to use the AccuLink Throttle Position Sensor. AccuLink TPS system is only available to COMPUSHIFT owners.

COMPUSHIFT Mini for GM 700-R4 and GM 200-4R The COMPUSHIFT Mini is a standalone plug-and-play system designed to control the torque converter clutch on GM 700R4 and GM 2004R transmissions. The system uses a miniaturized version of the same control software and electronics as the COMPUSHIFT II. The built-in display and keypad lets the user adjust and tune for their specific application and diagnose problems should they occur. The easy to read screen can display current vehicle speed, throttle position, transmission pressure, 4th gear/overdrive activity, torque converter clutch engagement, and allow for further custom tuning. The controller can can drive an electronic speedometer as well. Unlike other control modules that use vacuum switches or a simple delay timer, the COMPUSHIFT Mini uses throttle position and vehicle speed to optimize torque converter clutch control. Installing the COMPUSHIFT Mini is a straightforward operation if you are familiar with working on cars. No special considerations are needed when driving with the COMPUSHIFT Mini. Once tuning is complete, the COMPUSHIFT Mini can be mounted in its final location and left alone. No further adjustment or maintenance is needed. Properly tuned, your vehicle should have better gas mileage during cruising, and be more responsive to the throttle. The kit ships with all of the parts that should be needed for the installation including COMPUSHIFT Mini Controller with keypad, wiring harness, speed sensor and fittings, hydraulic pressure sensor, hook and loop fasteners, terminals and cable ties. Supported Transmissions

• GM 700-R4
• GM 200-4R

Note: During the years that GM built these transmissions, a number of different combinations of internal switches and wiring looms were fitted. The transmission must have a proper internal wiring harness. It must use a 4th gear pressure switch that is normally open and switches to ground when 4th gear is engaged.  If you are unsure if your transmission is equipped with the proper solenoid and pressure switch please add on the components with the option button above.

This product required a throttle position sensor when used with a constant pressure valve body. Resources Refer to the COMPUSHIFT Mini Manual for details on how to set up and install the system. You may also refer to Compushift Mini 700-R4 Instructions.

The cable throttle position sensor is used with COMPUSHIFT in applications that are not suitable for the AccuLink TPS or direct connection to an existing sensor. Features

• TPS is supplied with all necessary hardware including a ratio adjustment arm and bracket to mount the cable near the throttle linkage.
• The sensor is contained in splash-proof box that can be mounted in the engine compartment, under the car, or inside.
• The cable housing has a quick release lock / unlock feature that allows for easy adjustment.
