Rotunda Transmission Tester

DESCRIPTION
Use Rotunda Transmission Tester 007-00130 (part of Rotunda Transmission Tester Kit) with Rotunda 4R44E/4R55E Overlay/Cable 007-00106 in Transmission Tester Kit, Rotunda Transmission Range (TR) Sensor Cable "E" 007-00111 with Digital TR Sensor Overlay 007-00131 or equivalent to diagnose electronically controlled transmissions. The following instructions outline the set up and use of this tester in the Pinpoint Tests.

Bench Mode: acts as shift solenoid selector for click testing.
Drive Mode: acts as forward gear selector in place of vehicle's powertrain control module (PCM) controlled shifting. Hydraulic safety mechanisms and overrides are built into the transmission.
Ohms Check: allows technician to measure ohms and to check for presence of diode on specific solenoids.





OVERLAYS AND ADAPTERS
1. Overlay and Cable Correctly Installed LEDs: Only LEDs with the (O) symbol will light when the overlay and cable are correctly matched.
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 at VPWR).
^ All LEDs light orange during On-Board Diagnostics.

3. Solenoid Activate Buttons: Energize respective solenoids during click testing and activate selected circuits during DRIVE mode testing.
4. Tester Mode Switch: Selects operating mode, either BENCH or DRIVE.
5. Solenoid Select/Gear Select Switch: Has three functions:
^ BENCH MODE: acts as shift solenoid selector for click testing.
^ DRIVE MODE: acts as forward gear selector in place of vehicle's powertrain control module (PCM) controlled shifting. Hydraulic safety mechanisms and overrides are built into the transmission.
^ OHMS CHECK: allows technician to measure ohms and to check for presence of diode on specific solenoids.

TESTER JACKS
1. VPWR Pin Jacks (red): Vehicle Power (VPWR) test points for solenoid circuits.
2. Solenoid Signal Line Pin Jacks (black): Signal line test points for solenoid circuits.
3. BAT + (red) and BAT - (black) Pin Jacks: Battery reference points when measuring circuits for shorts.
4. TFT Pin Jacks: Test points for transmission fluid temperature sensor.
5. TSS Jack: Test points for TSS sensor.

LEDS AND CONTROLS
^ LED turns RED when solenoid activates and OFF when solenoid deactivates.
^ LED turns GREEN if an activated solenoid/harness is shorted.
^ LED remains OFF if an activated solenoid/harness is shorted to ground or no continuity.
