Very interesting to watch. I wonder how the rebuilder gets his nails clean! Probably wears gloves whenever he goes on a date....

Old cast iron Cruiseomatic Ford. I rebuilt a ton of those units back in my day in our shop. Tough old trans but they would varnish up bad like that one did. Fords fluid back then would break down and turn to sludge.

Transmission repair business- a headache on good days. Everything must be perfect or the trans comes back out and apart, for free. No mistakes. One assembly error or defective part and you get to eat the entire job for free.

Those were the easy days with 3 speed automatics. No OD or TCC. Now shops get to repair 6,8 and 10 speeds. No thanks. I did my sentence for 42 years so younger guys can have at it.

The guy who built the Powerglide for my race car (and for many, many other guys) used to build them one-handed.....

'Cause he only had one.

I just rebuilt my A727 in my GTX. Also did a valve body kit install. I wasn't quite that quick or well prepared.

Interesting how similar most of the internal components are for the various auto transmissions. I was OK through breakdown into major components and the inside of mine was pretty clean. Then my smart *** brother sent me an email with an exploded view of all the component parts and said good luck. That exploded view about made my head explode - replied thanks a lot.

But as long I kept the major components grouped together and in semi-assembled fashion when I would quit for the day and after messing with it, cleaning parts, measuring parts and examining parts for wear over several days - it all became very familiar and pretty easy to work on.

Now I'm getting ready to order parts to rebuild and convert my Muncie to a M22W - Larry at D&L said if I could tackle the 727 the Muncie would be easy.

Dan, the Muncie will be a piece of cake. Pops taught me how to rebuild those at 17 years old.

My father, who is 70 years old now was the automatic transmission tech for Miller Motors Buick dealer in Baltimore when he was 18 years old. I know it looks difficult and there are lots of parts, but once familiarized with anything with lots of parts it becomes second nature.

In 1978 my dad started his own electric forklift service business after about 14 years experience and I remember seeing all the parts and thinking ''how could I ever know where they all go?'' I've now been in the business for 34 years as a tech and part owner and I can say there are all types of gear boxes, speed reducers, and intricate things to tear down and rebuild. Even though I always look at a job with a little fear or cautiousness I still have to pay attention and just do it.

Notice how the tech in the video lays parts out in a particular sequence. That's part of how he remembers how it all goes back together. I agree, one part misplaced or left out is always a disaster without a doubt.

ILBMF - I kept careful track of the parts I was throwing out as I substituted new ones. It was a big relief when it was all back together and I didn't have any parts left over except my box of carefully substituted parts. But I still wasn't nearly as well organized as that guy in the video.

I do the same thing. Recently I had a gear box out of some strange forklift called a Bendi. It had a gear that broke and caused hardened metal fragments to get lodged everywhere causing disassembly to be a nightmare which is a huge distraction. It was a planetary gear setup. After getting through it without a hitch I can't wait for the next one.

OMG, I respect someone so organized and efficient. He certainly earns every dollar he makes. I never though it would be so complicated. Thanks for the video.

This^^^. I have rebuilt a few 3 speed autos and 4 speed autos, and really, they are, like anything else, just a lot of 'parts'. But you need specialized tools, and you need super-duper cleanliness, and you need to not make a single mistake. It only takes a second to burn up a set of paper lined clutches because you didn't pressure-check a servo that had a rolled seal and lost pressure.....Anymore, particularly with the lack of skilled tradesmen and the complexity of the units, auto transmissions are simply removed and replaced with reman or new units. The last ones I was doing were front drive 3T40's in GM cars, and they had the diff incorporated into the unit. Simple trans, but still a PITA. No thank you!

I have 2 controlled coupling Hydra Matics, a Powerglide, a Dynaflow, 2 727's and a cast iron Cruisomatic (MX), so I was forced to become a student of each, though I use pros to tear them down. A man's got to know his limitations....

Only thing I've done I didn't see done in the video is to measure the total thickness of the clutch pack/steels before getting them wet and dropping them in.
