The year was 1977. I operated the cut open machine for the 400 THM torque converter in Dept. 433, Torus Division at Hydra-Matic Willow Run. The converters were rejects from testing; they were removed from racks, and were hand placed, hub down, into a massive chuck that clamped around the outside of the impeller body, (which we simply called the "pump") with the cover, pilot and lugs facing upwards. A plexiglass door was pulled down and the machine was cycled. A thick triangular cutting tool was indexed into the weld as the unit spun. The cycle time was about a minute and a half or so...it seemed. You knew it was almost done when ATF fluid began to get flung on the cover door of the machine. The machine cycle ended. Then you removed it, and the converter cover was separated, or almost separated from the impeller housing but still held by a bare "thread" of the weld, sometimes....then you banged the thing on a metal fixture, if you had to......to pop it open on a table that had a grated surface so that the fluid could drain. Then the internal parts were separated, and sorted down their respective conveyors to be sent thru a washer and put into tubs to be sent back their original department for inspection...and rebuilt...if possible. The bearings were never reused and were junked. Did I mention that the THM400 torque converter, filled with ATF, is heavier than most torque converters? The production on that job was 200 units per shift. My partner and I figured out the most time efficient method to do that job, the idea was to keep the machine running with as little time between cycles as possible, and working together, we were able to work our asses off and get 200 units by lunch time. Then go hide. The boss was happy because we always got the count. It was hard, heavy, filthy work, and guessed what we smelled like when we went home every day? Transmission fluid...you can bet. One thing that used to happen, was that occasionally when the cutting tool got really dull, the chips coming off the operation, would get very hot, and cause a fire inside the machine, aided by the ATFluid igniting...it was so hot. We would look down the aisle to see if the boss was around....and enjoy the fire for a minute as it grew before we reached for the extinguisher...heh. Fun times. In the 3 years I spent in Dept. 433, I did most of the operations making the impeller unit, and can remember the step by step manufacturing process in fairly great detail....Then spent some time in Dept 431 which was the torque converter assembly dept, where they were assembled, welded together, filled with fluid, balanced and tested. I have been retired from Hydra-Matic Willow Run since 2008, and spent several years making planetary pinion gears...and many other jobs. They closed in 2010, and the building was torn down in 2014. It was originally the Willow Run B-24 bomber plant, built by Henry Ford...in 1941...so much history there...Thanks for reading this.

We took our super-charged V6 Holden back to the automatic gearbox rebuilder, because it started 'porpoising' on acceleration. We though he had screwed up the rebuild, but after he test-drove the car for 10 minutes, he pointed out that the air intake hose was split and sucking in air where is wasn't supposed to. We fixed it with duct tape. The auto gearbox was actually perfect. It wouldn't surprise me if it was the same thing here.

Torque converters work by directing fluid at variant angles from the pump side to the drive side via the fins or sometimes called blades, in my understanding competition converters use a more aggressive fin angle increasing flow rate and pressure through the torque drive, if that's the case just cutting one open you are not going to see anything different unless you are going to use pitch angle gauges and micro measures ect to see the difference.

When watching the converter spin on the lathe, you can see the light reflection moving up and down indicating that the housing is not consistent. Not sure if that could contribute to the "proposing" but if the fluid is controlled/contained by this part of the housing, at certain rpms you might have a vibration issue... Yes? No?

Going by personal experience,changing the converter in an automatic is probably the most drastic change,short of nitrous,that you can make.It can turn an otherwise decent car with a strong motor into an all out stoplite killer.Going from the stock 1800 stall in my 69' Firebird to a 3200 stall made it a tire roasting animal and plants your eyeballs in the back of your head in 9" slicks at the track.0-60' dropped drastically as did E.T. but did loose 4 mph in the traps.But the win light comes on!I'll give up the 4mph any day for the E.T.

About 90% of the transmission fluid is held inside the torque converter, when you drop the transmission pan only a few quarts come out, old fords had drain plugs on there converters so you could do a complete drain and refill. That's how a line lock works on a automatic transmission it stops the fluid flow off to the converter then when your ready hit the button and it releases all that fluid into the converter launching the car forward.

ATI has a dyno for testing, but that's not what this video is showing. This a simple cut open for inspection of a NON-ATI converter. Once inspection is complete, the unit can be welded back together in less than a minute. The purpose of the video was to highlight the modifications ATI makes to a standard lathe to allow it to cut open converters, as ATI sells an entire line of machines to shops that allows them to service their own converters - from cutting them open, to testing internals, welding them up and finally machines to test them for leaks.
