Bộ cần số AMG GLA45 4MATIC hộp số ly hợp kép 7 cấp 724.0 7G-DCT

Function: Electromechanically actuates synchronizer sleeves for gear engagement in Mercedes-Benz transverse DCTs (e.g., A-Class, CLA). Key Components: Forged Aluminum Forks: Anodized contact surfaces (OEM A2462800180 ) Guide Rails: Hardened steel with PTFE coating for low friction Position Sensors: Hall-effect type for TCU feedback (0.1mm accuracy) Failure Modes: Fork Pad Wear: Causes incomplete synchro engagement (grinding noise) Rail Scoring: Contaminated fluid creates drag

Cụm ly hợp đa đĩa sau hộp số tự động U760E U760F

Function: Transfers Quattro AWD torque to rear wheels via crown wheel/pinion (4.25:1 ratio) with integrated electronic differential lock. Key Features: Hypoid Gearset: Case-hardened steel (HRC 60+) with lapped contact pattern Haldex Coupling: Gen 5 multi-plate clutch (0-100% rear bias) Thermal Management: Temperature sensor triggers cooling protocol (>250°F) Failure Modes: Bearing Pitting: Contaminated fluid (G 055 529 A2) causes whine Clutch Pack Wear: Leads to AWD

Cụm ly hợp đa đĩa sau hộp số tự động U760E U760F

Function: Engages specific gear ratios (often overdrive/reverse) by locking planetary gearset elements via hydraulic pressure. Key Components: Clutch Drum: Hardened aluminum with precision splines (OEM-specific coating) Friction Plates: Carbon-fiber or paper-based with grooved design for cooling Steel Plates: Laser-cut with anti-stick coatings Piston Assembly: High-temp seals (Vitron/HNBR) for 100+ psi apply pressure Failure Modes: Plate Glazing: Overheating causes slippage

U760E U760F Cụm bánh răng hành tinh phía sau hộp số tự động 3572033050

Function : Final torque multiplication stage in planetary transmissions, typically controlling overdrive/reverse gear ratios. Key Components: Sun Gear: Hardened steel core with ground teeth (HRC 60+) Planet Carrier: Precision-machined with needle bearing pockets Ring Gear: Often integrated into transmission case Failure Modes: Sun Gear Spline Wear: Causes ratio slippage (P0730-P0733 codes) Pinion Bearing Failure: Results in gear whine (check endplay

Phiên bản nâng cấp mới của Cụm biến mô thủy lực hộp số tự động 34200016060 cho SUZUKI Jimny

Function: Upgraded torque multiplier for 4-speed automatics (e.g., Suzuki M13A/M15A engines), improving low-RPM torque transfer. Key Improvements vs OEM: Stamped Turbine Blades: 17% thicker steel for reduced flex at high temps Triple-Lock Clutch: Carbon friction material (handles 220°C vs OEM 180°C limit) Brazed Welds: Eliminates factory weak points near impeller hub Failure Resistance: Anti-Shudder Design: Revised damper springs reduce P0741 codes Seal Upgrade: Viton front

Kích hợp trống bánh xe ngược của hộp số 4R75 với một đường nối một chiều ở vị trí thấp cho Ford

Typical Faults: One-Way Clutch Roller Jamming Symptom: Harsh 1-2 upshift or delayed reverse engagement (P0730/P0756 codes) Cause: Contaminated fluid or sprag spring fatigue Drum Spline Wear Symptom: Reverse slippage or metallic noise Trigger: Hard shifts causing torsional stress Thrust Washer Failure Symptom: Axial play >0.25mm (whining in reverse) Root Cause: Improper assembly torque Critical Checks: Sprag Clutch Test: Should lock counterclockwise only Drum Runout:

General Motors 6T30 Tốc độ thấp Reverse One-way Clutch Hub Cho năm 2013 Và các mô hình sau của Cruze Sonic 1.8L

Typical Faults: Sprag Spring Fatigue Symptom: Harsh reverse engagement or 1-2 shift flare (P0730) Cause: Repeated torque reversals weakening springs Inner Race Wear Symptom: Grinding noise in reverse Trigger: Hardened ATF failing to lubricate contact surfaces Hub Spline Stripping Symptom: No movement in reverse (with forward gears working) Root Cause: Improper heat treatment during manufacturing Critical Checks: Sprag Engagement: Must lock counterclockwise only Radial Play:

6R80 CVT hộp số tự động bánh răng trực tiếp "B" Bộ trống ly hợp

Typical Faults: Spline Stripping Symptom: Slippage in direct gear (P0733/P0776 codes) Cause: Hardened steel splines wearing against aluminum drum Piston Bore Scoring Symptom: Delayed 3-4 upshift Trigger: Contaminated ATF acting as abrasive Drum Cracking Symptom: Sudden loss of drive (metal debris in pan) Root Cause: Thermal fatigue near lubrication ports Critical Checks: Spline Engagement: Should have 0.03mm fails) Drum Runout: >0.05mm requires replacement Pro Tip: Use

Cvt Automatic Gearbox Output Shaft cho Ford F-150 6R80

Typical Faults: Spline Wear Symptom: Clunking on acceleration/deceleration Cause: Micro-movement from torque reversals Bearing Surface Scoring Symptom: Whining noise at highway speeds Trigger: Contaminated fluid or misalignment Seal Groove Erosion Symptom: Persistent fluid leaks Root Cause: Abrasive debris in ATF Critical Checks: Runout: >0.08mm requires replacement Spline Play: >0.2mm rotational movement = fail Hardness Test: Should be 58-62 HRC Pro Tip: Always inspect
