Packard Forum Index » Pre-War (1899-1942)

Hello. This is my first post on this forum. I am looking at a very nice driver 1807. It doesn't come with Econo-drive - just the three speed transmission. My questions to you learned folks:

(1) Are Econo-drives easily available?
(2) Can they be installed with relative ease?
(3) Are they worthwhile for a driver?

Thanks.

Hello Martin,

Welcome to the forum. Allow me to offer my opinion on your questions.

(1) Are Econo-drives easily available?
Yes / No - The OD tranny itself will be fairly easy to find, the other detail items will be much tougher. It all depends on how you want it to function. Like factory = lots of parts. Bare bones = An actuating cable and a toggle switch.

(2) Can they be installed with relative ease?
Yes / No - It is a tighter fit than the non-OD tranny. The tough part is installing everything associated including switchs, relays, and wiring. Also need to shorten the driveshaft. A job requiring moderate mechanical skill and intermediate electrical skill.

(3) Are they worthwhile for a driver?
YES! In my personal application the car goes from being wound up tight at 45 / 50 mph to confidently cruising at 60 / 65 which only makes all the difference in the real world. You also have the option of installing a high speed gear set. A good friend has low 3's in his 40 180 and it is just magnificent on the highway.

Best of luck,
Jim

In response to your questions:

(1) Are Econo-drives easily available? - You'd need a complete system and these are probably hard to come by. Accumulating all the parts would be feasible but probably a long slow and expensive process.
(2) Can they be installed with relative ease? - Would involve some modifications to the chassis for the greater length of the trans/OD unit and clearance for solenoid and governor as well as shortening tail shaft.
(3) Are they worthwhile for a driver? - Very much so with the major advantage being improved economy.

Saying all that, there are much more learned and experienced Packard people here who should be able to provide more detailed answers than mine.

And don't forget, WHEN you acquire the '40 1807 please include it in the Packard Owner's Registry here, together with a pic, any known history and how you acquired it?

Not disagreeing with Jim's comments, just let me add that a 1941 senior w/o overdrive would probably have a 3.92 rear axle ratio which will permit comfortable cruising at 60 mph or so. Not quite sure what axle ratio of 1940 senior w/o OD would have but the 356 engine is shorter stroke than a 39 Super and would be more comfortable at higher speeds. Even my 34 Eight with a 4.69 rear (and 17 inch tires) is comfortable at 45-50 (but not much more). Also remember that the OD-equipped cars usually had a different rear axle ratio than those w/o it; you don't necessarily have to change the ring & pinion, but the vehicle will have better driving flexibility if you do.

I think a lot depends on what your intended uses are for the car and what kind of highways it will be driven on.

Lots to think about in the responses. I have closed the deal on the car and expect it to be trucked to me something late this month. Once I have it in hand, I'll post it in the registry.

As far as driving goes, I did want to be able to do reasonable speeds when on the interstate. About 30 years ago I used to drive a 1949 Eight at reasonable interstate speeds as well as a 1941 Buick and 1950 Buick. Reasonable in my (alleged) mind being in the 60s or so.

I'll have more questions beyond a doubt. Thanks.

Hi Martin,

glad to hear you obtained the car. Regardless of what you may or may do transmission wise I think you will find the car to be very enjoyable.

May I ask what body style?

One other suggestion - I would strongly suggest getting a copy of PACKARD 1940 a pivotal year by Jim Hollingsworth. This is a magnificant publication that will answer many questions and is a highly enjoyable read.

Congratulations!
Jim

Jim:

It is an 1807 five-passenger four-door touring sedan.

I'd like the book. Where can I get a copy?

Martin, I will PM you the information.

Jim

Martin,
for including your '40 One-Eighty Super Eight Custom in the Packard Owner's Registry. Looks Good!
