It is a commercial van, but not a Sprinter. It is a funky looking front drive full sized van that I think was designed in Europe, (and thus the funky look.)

They have the sloped nose of those other vans, but then it looks sort of blunt at the bumper.

I've heard they are pretty good vans and they are pretty popular among businesses around where I live. I see them a lot.
 
Seems like a stupid idea to rebuild a 500,000 mile transmission. All the hard parts that have 500,000 miles of wear will still be in the rebuild. Not a big issue at 200K, but at 500K?

Hard to believe this is a derivative of their FWD 4AT's.

Snark on: dude look real practiced at tearing it down... like he had practice or something...

Snark off: Bodes well in general for these transmissions. I wonder if that van is lighter than the typical Carvan? It certainly lives a more ideal life, nothing but highway miles, little stop and go. Also didn't look terrible to tear into.

Question: when he says things look "good" what does that mean? I mean, if I pulled out a bearing or friction with 500k on it, I might not give a rip if it was completely worn out, just that it didn't have grooves in it, indicating that any mating hard part was bad, or that garbage had been circulating through the system. I'm guessing he means, these parts could be reused.

This guys is a transmission specialist. He has quite a lot of teardown videos of BMW, Audi, Honda, Toyota, GM transmissions.
So yeah, he is quote seasoned not just with chrysler transmissions.

Yeah, I figured he was a pro. Being a Toyota fanboi I simply couldn't refuse a good opportunity to poke fun of--even if it's at miles that that the vast majority of Toyota's will never see, and without the Toyota tax to boot.

Yeah, I know Chrysler makes it quite easy with their many, many blunders

That 62TE looks pretty good for that mileage, many automatics don't make it that far. I'm shocked at how fast he got it from whole to stripped in less than an hour.

Chrysler trannies are much maligned - but they aren't that bad, as long as care is exercised to use ATF+4, the problems the 42TE/A604 had were quick lubes and indie shops as well as the driver dumping in Dexron fluid.
 
Pretty much that. Half a pint of Dexron would kill a 604. Making things worse, the 3-speed automatics actually called for Dexron!

They honestly come apart fast. The units I do I have it apart in that time, some times a little less

Another way to look at it, which I've thought of on my current 290k mile transmission in my Cutlass...if it lasted this long the tolerances must be just right, if you rebuild this unit it might last just as long again.

From what I understand, the 4AT's still had a problem with a pin in the diff. That can catastrophically take one out.

That's what failed in my coworkers old caravan. The tranny guy said it only fails if you spin the tires with the wheels turned.

I dunno about that, I get the impression that the diff pin could just back out on their own. Anecdotal evidence off the web and all that. Spinning the tires seems to take out diffs in general (the spiders take a lot of abuse doing that, the rest of the time they are doing "little"). But Chrysler changed the pin retention a few times--been a while since I looked--for a while I thought about buying an older Caravan and then being prepared to just rebuild the trans if it went bad on me, so I spent some time thumbing through pages.
