Note: This is the first in a two-part series on proper parting procedures. In Part 1, some basics.
When the first automatic transmissions were introduced in the late 1930s, the fluid coupling was routinely serviced as part of a transmission overhaul. The fluid coupling was bolted together and servicing it didn’t require any skills that a regular mechanic wouldn’t have. When the fluid coupling evolved into the torque converter, it was still a bolt-together unit and the only new challenge for the mechanic was to learn about stators.
But then everything changed. The torque converter became a sealed unit and even the best mechanics weren’t equipped with the machining and welding skills necessary to rebuild these new units. It’s not hard to see why in-house converter rebuilding facilities were so slow to develop.
