Tamburo frizione anteriore, albero pieno, per la trasmissione 4R70E, 4R70W e 4R75E
The **forward clutch drum with solid shaft** in an automatic transmission: 1. **Power Transfer Hub** – Connects input torque to planetary gearsets for forward drive. 2. **Clutch Pack Anchor** – Houses friction plates/steels engaged hydraulically (D/1-2-3 gears). 3. **Direct Mechanical Link** – Solid shaft ensures rigid torque delivery (no flex vs. hollow designs). 4. **Durability Focus** – Resists torsional stress from engine load. Failure = forward gear loss or shudder!
Mozzo frizione Audi ZF 8HP55A, fusioni a sei pezzi 1087475012
The Audi C' clutch hub assembly is a critical drivetrain component in dual-clutch (DSG/DCT) or multi-speed automatics. Key points: Function – Transfers torque between clutch packs and gearsets, enabling smooth shifts. Material – High-strength steel or alloy, often heat-treated for durability under load. Design – Splined or grooved to engage clutch plates/friction discs; may integrate bearings or bushings. Failure Modes – Wear on splines/grooves, cracking, or warping due to
GA8G45AW Cablaggio del corpo valvola della trasmissione automatica 24007936442 per BMW X1 F48 con versione sensore doppia temperatura olio
The automatic transmission valve body wiring harness is a crucial electrical interface, connecting solenoids, sensors, and switches to the TCM (Transmission Control Module). Key points: Function – Transmits signals for solenoid activation (shift control, pressure regulation) and sensor feedback (speed, temperature). Components – Includes terminals, connectors, and shielded wires to prevent EMI interference. Common Issues – Broken wires, corroded pins, or poor connections

GA8G45AW 4FA040 Gruppo convertitore di coppia idraulico 24408699936 Per Mini F54
"The 4FA040 torque converter is a hydraulic coupling unit with three key functions: Torque Multiplication: 2:1 stall ratio (approx.) for initial acceleration via stator clutch. Lock-Up Clutch: Electronically controlled friction disc (engageable above 25 mph) for direct drive efficiency. Cooling: Integrated impeller circulates ATF to the radiator cooler. Common Failures: TCC shudder (P0741/P2714 codes) from worn clutch material Needle bearing wear causing turbine wobble Seal
Filtro olio interno della trasmissione a doppia frizione 7DCT330 5501673496
Location: Typically housed in the transmission valve body or oil pan (serviceable without full disassembly). Function: Filters 5-10 micron particles from transmission fluid, preventing solenoid and clutch pack contamination. Material: Multi-layer synthetic fiber or metal mesh construction for high flow (3-4 L/min) and heat resistance (up to 130°C/266°F). Service Interval: Recommended every 60,000 km (37,000 miles) or with fluid changes. Clogging triggers P2714 (pressure
General Motors 6T30 a bassa velocità con spina retrograda a sensore unidirezionale Cruze Sonic 2013 e successive
"The 6T30's low/reverse one-way clutch hub is a critical rotational control component in the transmission's planetary gearset. Key characteristics: Function: Engages during low gear and reverse to prevent counter-rotation, while freewheeling in other gears. Common Issues: Prone to wear or roller clutch failure, causing slipping in low/reverse (common symptom: delayed reverse engagement). Material: Typically hardened steel construction for durability under torque loads.
