About This Part

This friction module is used for rebuilding the internal clutch assemblies of the MDKA automatic transmission. Comparable MDKA friction modules are configured for the 1st, 2nd, 3rd, 4th/5th, and low-hold clutch circuits, making transmission-code confirmation and direct comparison to removed components essential before installation.raybestospowertrain

Fitment Verification

Confirm the MDKA transmission code, original friction plate count, plate diameter, spline configuration, and clutch location before ordering. Do not assume every Honda or Acura vehicle from 2003-2004 uses the same transmission or friction arrangement.

Vehicle make, model, drivetrain, engine, and year alone are not sufficient to confirm internal transmission-part fitment. Verify the application using the transmission identification code and your original parts.

Repair Guidance

Choose this friction module for a properly diagnosed transmission rebuild where worn, discolored, heat-affected, or damaged friction discs require replacement. Slipping, flare between shifts, delayed engagement, harsh shifting, or burnt fluid may indicate clutch damage, but those symptoms can also be caused by hydraulic pressure loss, valve-body issues, worn drums, damaged steels, seals, solenoids, or electronic control problems.

Have a qualified transmission installer inspect related clutch steels, drums, pistons, seals, bushings, bearings, valve-body components, and fluid passages before reassembly. Follow the service information for clutch clearance checks, assembly sequence, transmission fluid fill, and any applicable relearn procedures.

Fluid Service

Use the transmission manufacturer’s specified ATF. If adding Lubegard ATF Protectant during service, verify compatibility with the specified fluid and follow the product directions; it does not replace mechanical repair of worn or damaged components.
