All bushings are inspected and replaced as required and 100% of friction components are replaced with upgraded heavy-duty parts. Drum assemblies are air checked and side play is checked to assure proper clearance. 100% of seals, o’rings and gaskets are replaced and 100% of solenoids are checked and replaced if they do not pass duty cycle tests. Internal wiring harness are checked and replaced, as necessary. Valve bodies are disassembled, cleaned, and measured for wear. Valve body valves and valve bores are inspected, and valve bores are machined as required. Completed valve bodies are tested for proper operation prior to dyno testing. Transmissions are assembled, end plays are set, and fasteners are torqued to the required specification. 100% of transmissions are dynamometer tested to ensure proper pressures and shift quality throughout the operating range. All upshifts and downshifts are checked against preset parameters. Torque converter stall speed and lockup is verified on the dyno test. Transmission park locking mechanism is checked during dyno test.
