Key Features of the A960E Manual

To summarise the utility of this essential guide, here's a quick overview:

Applications of the A960E Transmission

The A960E is a robust 6-speed automatic transmission designed to enhance both fuel economy and driving performance. Its versatility and reliability have led to its adoption in several notable Toyota and Lexus models, making the repair manual relevant for a specific range of vehicles. These include:

• 2006 Toyota Lexus GS 300
• 2007 Toyota Lexus IS 250
• 2012 – present Toyota 86/Scion FR-S/Subaru BRZ

The inclusion of a multi-mode automatic transmission with paddle shifters in some of these applications underscores the performance-oriented nature of the A960E, which, while offering an engaging driving experience, also introduces specific wear patterns that technicians need to be aware of.

Common Technical Issues and Repair Guidelines for the A960E

While the A960E is a durable transmission, like any complex mechanical system, it is subject to specific wear and tear, particularly under certain driving conditions. Understanding these common issues is crucial for timely diagnosis and repair, extending the lifespan of the gearbox significantly.

Torque Converter and Fluid Contamination

One of the most frequently encountered issues, especially with vehicles that utilise the sports mode or experience aggressive driving, is the accelerated wear of the torque converter friction material. This wear leads to several cascading problems:

• Friction Wear: The A960E's torque converter, unlike some multi-clutch designs, typically uses a single friction disc glued to the piston for its lock-up mechanism. When this friction wears out, it generates debris and adhesive components that contaminate the transmission fluid.
• Fluid Contamination: Contaminated fluid becomes less effective at lubricating and cooling, and the suspended particles can cause abrasive wear throughout the transmission. Critically, these contaminants can significantly impair the functionality of the valve body, leading to erratic shifting and engagement issues.
• Lack of Lock-up: A worn torque converter friction often results in a lack of proper lock-up, manifesting as excessive slip, increased engine RPM for a given speed, and reduced fuel economy. Timely diagnostics and replacement of the torque converter components are essential to prevent further damage.

Oil Pump Unit Vulnerabilities

Another common soft point in the A960E is the oil pump unit. Vibrations from a worn torque converter lock-up mechanism can transmit to the pump, causing damage:

• Pump Seal Leakage: A common symptom is a leaking oil pump seal. If neglected, this issue can quickly escalate.
• Bushing Wear: Persistent leakage and vibration can lead to wear of the pump bushing itself. Continued driving with a compromised pump can ultimately result in the complete failure of the oil pump, leading to a loss of hydraulic pressure and severe transmission malfunction. This problem is often accompanied by wear of the torque converter lock-up solenoid, which controls the lock-up mechanism.

Essential Parts for an A960E Overhaul

When an A960E transmission requires an overhaul, certain parts are almost universally replaced to ensure a complete and lasting repair. Proactive replacement of these components can dramatically increase the transmission's resource before another major service is needed.

• Kit of Gaskets and Seals (without pistons): After the frictions burn, all rubber seals are typically replaced. Contaminated fluid is a primary culprit for the wear of Teflon rings, which, if worn, further contribute to fluid contamination. Replacing these prevents future leaks and maintains hydraulic integrity.
• Kit of Frictions: These are the primary wear items in the clutch packs. Once they are burnt or excessively worn, they must be replaced to restore proper engagement and prevent slipping.
• Kit of Steel Discs: Working in conjunction with the friction discs, steel discs are also prone to wear and heat damage. Replacing them along with the frictions and the gasket/seal kit constitutes a comprehensive 'Masterkit' for a thorough rebuild.
• Pan Gasket: This is a consumable item that should be replaced every time the transmission pan is removed, such as during an ATF change or filter replacement, to ensure a leak-free seal.
• Torque Converter Rebuilding Parts: Given that torque converter components are often the first to exhaust their resource, rebuilding the converter is almost always implied when the valve body or solenoids are repaired. This includes replacing the friction material and any worn bearings or seals within the converter.

Complete and timely replacement of these spare parts can add up to 70% of increased resource before the next overhaul, highlighting the economic benefit of thorough repair.

Electrics in the A960E: Solenoids and Diagnostics

The electrical components play a vital role in the precise operation of the A960E. The rebuilding of an older A960 unit often necessitates the replacement of its linear solenoids. These solenoids are critical for regulating hydraulic pressure and controlling shift points.

• Solenoid Selection: It's crucial that the selection of solenoids for the A960 unit is performed in accordance with the vehicle’s VIN-code. This ensures compatibility and correct calibration, as there can be subtle variations between different production runs or vehicle specific tuning.
• Lack of Driver Feedback: A peculiar characteristic of this reliable 6-speed automatic transmission is that drivers often do not receive noticeable signals indicating the necessity to replace worn-out spare parts, particularly the torque converter friction and solenoids. This is especially true for those who frequently engage in aggressive accelerations or driving with the torque converter clutch in a 'slipping mode'. This lack of obvious symptoms means that regular, preventative diagnostics are even more important to catch issues before they lead to major failures.

Maintaining Your A960E: Fluid Checks and Refill

Proper transmission fluid levels and quality are fundamental to the A960E's health. The process for checking and refilling the fluid, specifically the WS type ATF, requires careful attention to detail.

How to Fill a Transmission Overflow Plug

The A960E, like many modern sealed transmissions, often uses an overflow plug method for setting the correct fluid level. This process is critical for ensuring the transmission operates efficiently and avoids damage from under or overfilling.

1. Raise the Vehicle and Keep it Level: It is imperative that the vehicle is raised on a lift or jack stands and maintained perfectly level. Any tilt will result in an inaccurate fluid level reading, leading to either under-filling or over-filling, both of which can cause significant transmission problems.
2. Remove the Refill Plug and Overflow Plug: Locate both the refill plug and the overflow plug on the transmission pan or casing. Remove both. The overflow plug is typically positioned lower than the refill plug, allowing excess fluid to drain once the correct level is reached.
3. Fill with WS Type ATF: Using a suitable pump or filler tool, begin to fill the transmission with the specified WS type ATF from the refill plug hole. Continue filling until the fluid begins to overflow steadily from the overflow plug hole. This indicates that the fluid level has reached the bottom of the overflow tube.
4. Install the Overflow Plug: Once the fluid starts to overflow, immediately install the overflow plug. This prevents further fluid loss and sets the level correctly.
5. Install the Refill Plug: After the overflow plug is secured, install the refill plug. Ensure both plugs are tightened to their manufacturer-specified torque settings to prevent leaks.

It's crucial to use only genuine Toyota WS type ATF. Using an incorrect fluid type can lead to severe damage to the transmission's internal components, including clutches, seals, and solenoids, as it may not provide the correct friction characteristics or lubrication properties required by the A960E.

Why a Genuine Repair Manual is Crucial
