Techinical Info

The component with original code OE 46339731 è the’electro-hydraulic actuator mounted on TCT (Twin Clutch Transmission) automatic gearboxes used in various FCA group models. This module controls the operation of the two clutches and gears, ensuring quick, smooth, and synchronized shifting.

Technical characteristics of the’TCT gearbox actuator 46339731

The’actuator è a compact group consisting of an electronic part and a’unità hydraulic, responsible for’executing the commands received from the transmission control unit.

Main specifications:

  • OE Code: 46339731
  • TypeComplete electro-hydraulic actuator for TCT transmission
  • Power supply: 12V
  • Connection: CAN network with transmission and engine control unit
  • Integrated components: electric motors, hydraulic solenoid valves, pressure and position sensors
  • Approximate weight: about 11 kg

L’The actuator controls both clutch groups of the TCT transmission and coordinates gear selection in real time.

DIPA canò intervene to revise this module as well.

Functionalityà of the transmission actuator module

The’actuator è is’the element that physically executes the commands of the transmission control unit. It intervenes in the management of the dual-clutch automatic transmission through:

  • Electro-hydraulic actuation of clutches
  • Gear selection and engagement
  • Adjustment of hydraulic pressure in transmission circuits
  • Synchronized coordination with engine ECU and accelerator pedal sensors
  • Modesà automatic and manual sequential

The’actuator works in synergy with the sensors to ensure the perfect balance between comfort and performance, especially during accelerations and rapid downshifts.

Vehicles compatible with OE code 46339731

This actuator è used in TCT transmissions mounted on FCA models with gasoline and diesel engines, predominantly from 1.3 to 1.6 liters.

Examples of compatibilityà:

Alfa Romeo

  • Tonale

Fiat

  • Fiat 500X
  • Tipo

Jeep

  • Renegade
  • Compass

DIPA recommends to always check compatibilityà based on the specific engine code and chassis number.

Common defects of’actuator 46339731 and causes

The’TCT transmission actuator è is subject to thermal, hydraulic, and mechanical stress. Some recurring defects include:

Frequent failures:

  • Hydraulic pressure loss due to worn seals or contaminated oil
  • Clutch actuation error due to faults in solenoids or internal motors
  • Wear of clutches due to incorrect or delayed activation
  • Fault in the position sensor which compromises gear selection
  • Error in communication with the transmission control unit due to electrical problems

Typical symptoms:

The transmission fails to engage the gears.

Insufficient pressure in the transmission group.

Oil leak, possible black oil in the clutch circuit/reservoir.

 

Conclusions

L’the TCT OE 46339731 transmission actuator è is a fundamental component for the operation of dual-clutch transmissions installed on FCA vehicles. Failures in this module can compromise the’gear engagement, the’use of the automatic transmission, and driving safety.

DIPA supports customers throughout the entire relationship phase, from’order to’after-sales assistance. Weò can intervene to revise these components and restore them to full functionalityà, with savings on replacement costs and a benefit for the’environment thanks to’circular economy. Also ask about the availabilityà of new or alreadyà revised and ready in stock for quick replacements and reduced vehicle downtime.
