1967 727 rebuild -> which rockauto parts/set needed?

[Wolli]

Hello,

my 1967 Chrysler Town and Country hardly moves due to longer driving with less oil (I bought it in that condition) -> has a lot of slip in the forward gears. Now I will rebuild the transmission, but I am not sure, which set, brand and parts I have to order from rockauto.
Do you have any recommendation?

Best regards,

Lars

Normally, there are three kinds of items. "Frictions" which is clutch friction plates and any bands. "Steels" are the metal plates that go between the friction plates. "Seals" should include all of the rubber and plastic o-rings, gaskets, and seals needed to do the rebuild.

You can go a bit outside of the RockAuto realm of things and look for a B&M transmission rebuild kit. That should include three levels of rebuild. Stock, High Performance, and Race. All in the same kit. They also sell their own brand of atf, "Trick Shift", too. Probably from Summit Racing or similar.

As to fluid . . . TorqueFlite were pretty insensitive to fluid. Starting with the old "Type A Suffix A" fluid in the earlier 1960s. Then the Dexron-spec fluid from 1968 onward, to the latest Dexron III fluid, now termed "Type III" by ACDelco. Not sure how these might translate into the Chrysler "ATF+__" terminology, though. One of them is semi-synthetic and the latest ones are full-synthetic. At one time, there were comments about full-syn fluid and some rubber seals not playing well over time, but that was 20+ years ago. Of course, the full-syn will be more expensive.

In order to just get things going, you might initially fill with Dexron III and ensure everything is working well first. After a year or longer, then go to one of the newer-spec fluids?

To do things a little bit cleaner, you might get a 12V extractor pump to pump the fluid out via the dipstick tube before you drop the oil pan. Just have about 12 quarts worth of containers to put the old fluid in. Which can then be poured into the containers the new fluid came in, if desired. They used to be about $35.00 USD in Amazon.

Just some thoughts,

Is your engine stock? Do you plan any modifications to the engine to increase horsepower?

I have rebuild many 727's and 904's and I can give you my recommendations after you answer the above questions.

My car ('67 Monaco) sat in storage for 20 years, it was low on transmission oil and it would not shift into reverse (well, I could shift it into reverse but the car did not move). I had to add 2 liters of oil. I have since changed the shifter seal and the rear output seal and the o-ring on the fillter tube and a new transmission pan gasket. I did not change any bands or do anything else inside the transmission. You may not need to do that either other than fix the leaks.

Note that the 727, like all transmissions from the 60's and probably 70's have "non-lockup" torque converters. This type of operation is more stressful for transmission fluid vs the more universal lockup torque converter that is common for the past 30 years. There is more heat and shear stress on AT fluid in a non-locking torque converter, and a high-quality (and more expensive) fluid like Mobil ATF+4 will last much longer and perform better than the semi-synthetic (and cheaper) alternatives.

There is a Mobil ATF Multi-vehicle transmission oil available in Europe, I presume this includes Germany. It is listed as being compatible with Chrysler ATF+ / ATF+2 / ATF+3 / MS 7176E and several other Chrysler / Dodge / Jeep standards. Chrysler introduced MS 7176E in 1997 as ATF+3.

See this 2003 thread for more details:

Most or all of what ATF discussions and technical focus and opinion has been on for the past 30 years will pertain to transmissions with lockup torque converters and computer-controlled clutches. So there will be little hard data to point to when it comes to how the various oil options cope with our 50-60 year old torqueflites with non-lockup converters.

While I was typing this, I was having a short online chat with (a person or bot?) on the mobile.eu website. I asked if Mobile ATF+4 was available in Germany, he says "Let me check - No data regarding the product availability.". I then asked if Mobile Multi-Vehicle oil was available in Germany, the answer was Yes. I then asked if there was an available ATF+4 oil, after a few minutes he came back and asked for what vehicle, I answered with 1967 Chrysler Newport with torqueflight automatic transmission, fully expecting this chat to go off the rails at that point, which it did. Here is the response:

"unfortunately our system does not contains before 1980 specs. For more advanced support you can send us mail in English or German techdeskeurope <techdeskeurope@exxonmobil.com>"

I would still say that that the Mobile Multi-Vehicle oil is a valid option for you. You might want to go down this rabbit hole and see if the techdeskeurope has anything authoritative to say about your oil options.

In looking at ANY atf labeled "Multi-Make", you HAVE to read the back of the container to see WHICH "multi-make" it is mentioning! Some Aisian-spec "multi-make" atf is not for USA brands of vehicles, but Hondas and such.

The "Multi-Make" atf you want is the one which includes "GM Dexron" and "Ford Mercon" in the vehicle description on the container. I discovered this distinction in looking at atf at WalMart.

Enjoy!

As I said, this Mobil "multi-make" does list many Chrysler specs.

Mobil ATF Multi-Vehicle

Mobil ATF Multi-Vehicle is a premium fully synthetic lubricant formulated from selected high-quality synthetic base oils combined with an advanced additive system designed to meet the service fill needs of the broadest range of step-type automatic transmissions in vehicles from European...

But I think looking closely at the specs today has almost no value when trying to match them up with our old torqueflights. Those specs are dust now.

Where is the whale oil today in the 1967 ATF specs?

Just like engine oil and gasoline. Where is the zinc in today's oils? Where is the lead in today's gasoline? Replaced with ethanol that never used to be there.
