The Lamborghini Aventador ISR E-Gear Solenoid Seal Kit is a comprehensive set of replacement seals specifically engineered for the electro-mechanical solenoid valves in the Independent Shifting Rod (ISR) transmission system. These critical solenoids control the precise flow of hydraulic fluid within the transmission. Over time and under severe thermal conditions, the factory seals on these solenoids degrade, causing debilitating hydraulic leaks, pressure loss, and shifting failures. Designed to meet strict engineering tolerances, this kit enables a complete refresh of all solenoid seals, restoring factory-level flow control and hydraulic integrity to your vehicle without the need for an exceptionally costly complete actuator replacement.
Common Issues Even if your dashboard shows no active trouble codes, a complete solenoid seal refresh is required when your vehicle experiences the following issues:
-
Hydraulic fluid leaks originating from the transmission actuators or control unit.
-
Frequent or continuous running of the E-Gear hydraulic pump due to system pressure loss.
-
The transmission exhibits delayed, rough shifting, slipping, or low-speed juddering.
-
The E-Gear system fails to engage gears or unexpectedly drops into neutral.
Associated Diagnostic Trouble Codes (DTCs) When solenoid seals fail and hydraulic pressure drops, the transmission control module may log the following faults related to actuator or pump performance:
-
P17C3: Gear Selector Malfunction
-
P0914: Selector Lever Electrical Malfunction
-
P0840: Transmission Fluid Pressure Sensor/Switch "A" Circuit
-
P0944: Hydraulic Pressure Unit Loss of Pressure
Complete Solenoid Seal Kit Includes:
-
Full Set of Solenoid Seals: Precision-engineered replacement seals that service the electro-mechanical valves in the Aventador ISR transmission.
-
High-Performance Elastomers: Manufactured from advanced materials designed to withstand extreme hydraulic system pressures and high-temperature thermal cycling.
Installation Instructions & Best Practices
-
Cleanliness: The ISR hydraulic unit is highly sensitive to contamination. Ensure the work area and actuator assembly are meticulously cleaned before solenoid extraction.
-
Seal Lubrication: Lubricate all new elastomer seals with fresh OEM-approved hydraulic fluid prior to installation to prevent tearing during insertion.
-
System Bleeding & Adaptation: After reinstalling the rebuilt solenoids and the transmission actuator, a complete hydraulic system bleed is mandatory. You must use a professional Lamborghini diagnostic scan tool to perform a clutch kiss-point adaptation and shift actuator relearn procedure so the TCU can learn the refreshed solenoid flow rates.
