1994-2009 Nissan Altima Automatic Transaxle Service Manual

1994–2009 Nissan Altima Automatic Transaxle Technical Documentation

Tackle complex transmission jobs with precision. This technical reference manual details the 1994–2009 Nissan Altima automatic transaxle, focusing strictly on the RE4F04A and RE4F04V models. Whether you are tracing an electrical fault, verifying hydraulic line pressure, or doing a full tear-down analysis, this documentation removes the guesswork from your daily workshop routine.

Diagnostic and Control System Coverage

Instead of generic overviews, this manual provides exact diagnostic workflows to help you pinpoint issues fast. It breaks down the sophisticated hydraulic and electrical systems controlling gear shifts and lock-up functions. Technicians get direct access to 95 electrical circuit diagrams and 20 diagnostic flow charts.

The guide extensively catalogs internal components, including dual planetary gear systems, band servos, and clutches. If you are dealing with control unit errors, the detailed control-unit terminal inspection tables integrate perfectly with CONSULT system diagnostics, allowing you to monitor sensor inputs, duty cycles, and actuator responses accurately.

Critical Specification and Calibration Data

Accurate calibration data is the difference between a successful repair and a frustrated customer comeback. This publication includes the essential reference values required for bench-testing and system verification:

• Fluid temperature sensor resistance: 2.5 kΩ at 20°C (68°F) to 0.3 kΩ at 80°C (176°F).
• Line pressure solenoid valve duty cycles: 29% to 94%.
• Dropping resistor resistance: 11.2–12.8 ohms.
• Stall testing speeds: 2,100–2,400 rpm for Federal models and 2,150–2,450 rpm for California-specific units.

The manual also outlines explicit parameters for verifying valve clearance and end play during assembly and diagnostic testing.

Important safety notice: The technical data and specifications provided here serve strictly as a reference for diagnostic analysis. Always consult a certified technician before performing complex service operations on high-pressure hydraulic equipment or initiating structural drivetrain repairs.
