Every part of the transmission is scrutinized by our trained technicians. Cases are inspected for distortion, cracks, and bad threads. Cases are also checked for flatness at valve body mating surfaces to prevent cross leaks.
Hard parts, such as planetaries, pumps, gears, and shafts are individually checked for spline damage, correct tolerances, excessive clearances, stress fractures, and any unusual wear. Electrical components, such as solenoids, force motors, switches, and wiring, common in today's computer controlled transmissions, are also tested with special tools. Test boxes check solenoids and switches for proper operation under pressure while cycled with appropriate voltage.
