Company Profile
Product Details
Function: Transmits engine torque to the planetary gearset via engaged clutch plates (typically 1st-3rd/4th gears).
Key Components:
Input Shaft: Hardened steel with precision-ground splines (connects to torque converter)
Clutch Drum: Aluminum/steel hybrid with laser-welded piston channel
Integrated Piston: High-pressure seals (Vitron or HNBR) for rapid apply
Failure Modes:
Spline Wear: Causes clutch drag (delayed engagement, P0776 codes)
Drum Warpage: Overheating distorts sealing surface (>0.1mm runout = replace)
Seal Extrusion: Contaminated ATF degrades seals → pressure loss
Critical Checks:
Measure shaft endplay (<0.3mm)
Verify drum concentricity (dial indicator test)
Inspect piston bore for scoring
Pro Tip: Pre-soak new clutch plates in ATF for 30 mins – dry plates cause initial shift flare.
