What does the TT in two interlocking circles emblem on a GT Hawk stand for?

"Twin-Traction" aka: posi-traction.

Twin Traction. Studebaker's name for Positive Traction

[wlfrench]

Thanks. I didn't have a clue.

Twin Traction - that was their name for a limited slip (similar to posi-traction) rear axle.

Looks like Kerry beat me to the draw! CURSES!

ha-ha! now one of y'all can tell Wayne what to look for on the "pumpkin" to make sure it's still there.

[wlfrench]

Ok, what do I have to look for on the pumpkin to make sure the limited slip is still there?

There MAY be a tag on the "pumpkin", but that will not assure that the TT is still there. Take out the fill plug. Stick your finger in. If it almost immediately hits something, the TT is in there. If there is a lot of space, the TT is not there.
You could also check by jacking up the car and revolving the wheels.

Get it in some soft sand and gun it. Both rear wheels should show spin marks. Even if it is still there doesn't mean it still works only way to tell for sure is to test it.

Packard had it first

IIRC, the '56 Packard was the first to offer the Dana-Spicer limited slip as an option.

Makes one wonder about the decision makers at S-P Engineering, because if any Stude ever needed TwinTraction, it was the '56J. Then, in '57 when the Golden Hawk had 1/3 less low end torque, they decided to offer the TwinTraction option.

I understand that Packard had major problems with its 1956 limited slip axle.....No doubt by 1957 the 'bugs' were worked out, and Studebaker THEN decided to offer it as optional equipment.

It was also available on 1956 2E series trucks. Stude ran full-page ads in several national magazines announcing its availability.

Should we have a poll for most asked question ever? Ya gotta love it. This would have to be in the top five.

It seems SO obvious to us long time Studebaker owners, what with all of Studebakers' hyping it up over the years and all that, it is a "no brainer" for many of us, and hard to understand it being so confusing.


I guess you have to put yourself in the mindset of a 20-40 year old, or someone a bit older who grew up in a family that never mentioned the word Studebaker unless it was part of a joke!

Hmm, let's see, if you were born in 1974, that's ONLY 8 years AFTER the last Stude. was built.
