Universal transmission tester

A device for selectively a testing computer-controlled transmission that has an interface connector module and a plurality of solenoids that control a torque converter clutch therein, comprising:

• (a) circuitry for providing electrical power to said device;
• (b) an interface connector module having multiple pin connectors for connecting said device to said interface connector module of the computer-controlled transmission to be tested;
• (c) four (4) two-pole, six position rotary switches for selectively shifting said transmission to be tested to one of the transmission gears;
• (d) indicator means electrically connected to and activated by said rotary switches for indicating the selected gear;
• (e) circuitry enabled by said rotary switches to provide ground connection input to said transmission to energize at least one of the plurality of solenoids that control said torque converter clutch;
• (f) a single pole switch for selectively controlling the pressure in said transmission being tested;
• and,
• (g) means for limiting the current to said solenoids.

• (c) four (4) two-pole, six position rotary switches for selectively shifting said transmission to be tested to one of the transmission gears, two of said rotary position switches having poles grounded and the other two of said switches having both poles connected to a positive current source;
• (d) indicator means electrically connected to and activated by said rotary switches for indicating the selected gear;
• (e) circuitry enabled by one of said rotary switches to provide ground connection input to said transmission to energize at least one of the plurality of solenoids that control a torque converter clutch;
• (f) a single pole rotary switch connected through said interface connector modules for selectively controlling the pressure in said transmission being tested;
• and,
• (g) means for limiting the current to said solenoids.
