Just got done with a major tranny cleanup in my driveway this afternoon. My friend Bill, who previously gave me a very nice and complete slant six engine from his 1974 Dart, also just gave me the original numbers matching transmission for the same engine. This was an 87,000 mile power train before he pulled it from his Dart. He's in the process of installing a crate motor and wanted to give the original engine away. Anyhow, I picked the trans up from him yesterday and spent this afternoon cleaning it up. I first removed the broken off tranny cooler lines, then capped them with plastic caps. The torque convertor then went into the trash, and she was now ready for cleanin'. You can see how gunky and covered with oily crud it was. I first hit it with a can of Gunk engine degreaser, let that sit for fifteen minutes, then fired up the power washer. 3200 psi and twenty minutes later, she was looking great and ready for the steel wire brush. Once done with the brush, I cleaned her up with Comet cleanser and finished with a fresh water rinse down. I let her dry in the sun, and you can see the results.
There's just something very satisfying about restoring a crud covered fifty two old Torqueflite transmission. It's a really nice and complete core and matches the numbers on the Dart engine that's in my 1974 Duster. The Duster does still retain its original factory Torqueflite, so I'm not exactly sure what I'm going to do with this trans. For you numbers guys, here are the details: Part number PK 3681841 (PK means it was built at the Chrysler Kokomo IN transmission plant). Julian date 4525 (built on Sunday, Dec. 17th, 1973). 6336 (the 6336th trans built that day). G 172603 (the last seven digits on the Dart's VIN). And finally A-904-0 (molded on the bottom of the bell housing).
I'm glad that I saved this unit, as Bill was eventually going to scrap it. I can't really blame him as his garage is pretty small and the Dart takes up the whole space. I just thought that the original complete transmission ought to somehow stay with its factory motor, and I'm afraid that's the best justification that I have. At least it will now live in dry, safe inside storage and be ready for the next lifetime. Anyhow, not sure if anyone is really interested in this stuff, but here it is nonetheless. Be well and happy Mopar motoring all! (cruiser)

I need to do the same on a 727, but I don't expect to use it for a few years so I don't want to get water inside it.

Are the kids pissed of about their wagon?
 
The KD band screw has plenty of threads showing; good chance trans has little wear.

That's not really a problem on the old transmissions.

First I heard of looking at the remaining threads on that adjuster was with looking into diesel Rams.

@cruiser Why did you throw the original torque converter away? While you are so satisfied restoring a cruddy TF? Sounds odd.

Don't know about a 'problem', but if the adjuster has been screwed all they way in, the most likely cause would be a worn KD band........

Good question. When I rebuilt the tranny that's in the Duster right now (which is the factory original transmission), I installed a new torque convertor. I thought that if I ever had to use my backup tranny, I'd simply swap the converter to the replacement transmission. It's a really nice converter and works great, so I really have no use for the old one. Also, inside storage space is at a premium at my place. I couldn't find anyone that wanted the old converter, even for free. They all buy new converters for their rebuilds and aren't interested in putting in an older used one. Point well taken, though.
 
Nice job on the cleanup, she's a beauty... nice to work on clean parts too :)

I did get some water inside from the power washer - probably through the air vent. So after cleaning, I removed the pan and drained the oil - which contained a small amount of water. Once the oil drained out, I left the rest of the internals covered in tranny oil, then let it bake in the sun a few hours to drive out any remaining residual water. So now it's dry as a bone inside, although coated in oil. Discarded the filter, cleaned up the pan, then reinstalled the pan. All exterior openings are plugged, then I'll bag it in a large poly bag with some desiccant inside to keep everything dry. BTW, when I cleaned the pan, all I found in the bottom was some dark colored sludge - not too much. No metal shavings. Looked pretty normal. So she's in dry safe storage now and could probably be perfectly fine for the next fifty years if need be.
 
i'd put the converter back in the trans to keep crap out of the pump. it won't take up any more space sat in the bellhousing after all.
neil.
I have two transmissions in my shed/shop, and both of them have TC's installed in them, held in-place with a rubber bungee cord, for that very reason.

No it looks like Ill have to take Mr. Dirty (727) to the car wash. I'll plug the vent hole behind the converter, are there any other vent holes to be worried about??? I'll cap the cooler lines and drain as you did.

Thanks

That's the only vent hole that I know about.

i'd write ''no filter fitted'' on the pan before you bag it for storage. if you ever need it you'll forget you discarded the old one (i would, lol) and run it without one.

i've used old alternator adjustment brackets or bits of flat bar bolted to one bellhousing bolt hole so it presses against the converter, even a length of wooden batten from one side to the other with zip ties through opposing holes to do the same thing. either works. :thumbsup:

I wish I could remember the product but 20+ years ago I worked in a Ford dealership and our component rebuild guy used an aluminum cleaner to get ZF transmission cases looking really nice. He used it in a spray bottle, so I imagine they bought it in a gallon size container. I doubt many mechanics today would take that kind of pride in their work.

Be careful with the wagon, it may be worth more than the transmission. When playing with water, I also cap, off the input and output shafts.

Keep converter with it, not just to keep dirt out, because it worked as is & someone might need a spare, IF it's complete it's an easier sell.
