Tester Description

DESCRIPTION
Use Rotunda Transmission Tester 007-00130 and Rotunda AODE/4R70W Cable and Overlay 007-00122 or equivalent to diagnose electronically controlled transmissions. The following instructions outline the set-up and use of this tester in the pinpoint tests for the 4R70W.

OVERLAYS AND ADAPTERS
The following transmission tester overlays and adapters must be used with the Rotunda Transmission Tester 007-00130 or equivalent to properly diagnose the 4R70W transmission.
- Rotunda AODE/4R70W Cable and Overlay 007-00122
- Rotunda Transmission Range (TR) Sensor Cable "C" (MLP-C Cable) and overlay (007-00128) or equivalent.

TESTER JACKS
1. VPWR Pin Jacks (red): VPWR test points for solenoid circuits.
2. Solenoid (MCCC, EPC) Signal Line Pin Jacks (black): Signal line test points for solenoid circuits.

NOTE: The tester overlay is labeled for the MCCC solenoid. This is used to test the torque converter clutch (TCC) solenoid.

3. BAT+ (red) and BAT- (black) Pin Jacks: Battery reference points when measuring circuits for shorts.
4. TOT Pin Jacks: Test points for transmission fluid temperature sensor (TFT).
5. OSS Pin Jacks: Test points for output speed shaft sensor (OSS).

LEDs AND CONTROLS
1. Cable Correctly Installed LEDs: When LED is lit, the cable is installed correctly.
2. Status LEDs: LED OFF when not activated by tester (solenoid not activated, open circuit or signal line short to ground). LED green when activated by tester and current draw is correct. LED red when activated by tester and current draw is excessive (short to battery positive voltage (B+)). All LEDs light orange during self-test.
3. Solenoid Activate Buttons: Energize respective solenoids during click testing and activate selected circuits during DRIVE mode testing.
4. Bench/Drive Switch: Selects operating mode, either BENCH or DRIVE.
5. Solenoid Select/Gear Select Switch: Has three functions. In BENCH MODE: acts as shift solenoid selector for click testing. In DRIVE MODE: acts as forward gear selector in place of vehicle's PCM-controlled shifting. Hydraulic safety mechanisms and overrides are built in to the transmission. In OHMS CHECK: allows you to measure resistance (ohms).

INSTRUCTIONS
The Rotunda Transmission Tester 007-00130 or equivalent allows a technician to operate the electrical portion of the transmission independent of the vehicle electronics. This allows the technician to determine transmission concerns. The transmission tester usage is divided in five steps:
1. Preliminary testing and diagnosis
2. Installing the transmission tester
3. Static testing-engine OFF
4. Dynamic testing-engine running
5. Removing transmission tester and clearing diagnostic trouble codes
