Pantera trans

I would like to know why the Pantera trans. has to be flipped to be used in the GT-40.
I have a Pantera trans and also an Audi 5000 Turbo unit and I am trying to decide which to use so I may sell the other.

thank you VIC

You should not have to flip it. It uses the same drive configuration as the GT40, mid-engine, tranny in the rear. Who told you to flip it?

You may be thinking of the Porsche G50 boxes which are in front of the motor in 911s. Must flip or change pinon I beleive.

It may be that some kits don't require the ZF to be flipped, but the original GT used the box oriented with the input shaft below the centerline of the axles to minimize engine height. The Pantera's input is above for more ground clearance. They added ears to the cover for mounting.

Victor,
Save yourself the trouble, I have a freshly rebiult 5000 trans. New down to the needle bearings. I'll trade you for your ZF. You know, just to help you get the car on the road a little sooner

Hi Bob

Victor will need one of your bellhousings, will you sell him one, and if so whats the cost? I would also be interested in getting one.
I found that the input shaft on the ZFDS25/2 is 1" longer than the original GT40 DS25/1 so the bellhousing needs to be deeper (front to back)
Regards

cut or use a different shaft....

if it is to be used as meant too !

M1 etc also have different types of shafts...

ZFDS25 was the original box..
-1 is a developed/strenghtened one...
Also heavier....
Then came -2 etc...
Heavier still and developed.
All these came in a variety of out puts.

Watch the input shaft length carefully. When Safir P1116 was assembled by John Vermeersch with a 351, the input shaft was a couple thousandths too long and bottomed on the crank pilot hole. Took the thrust bearings out of the motor in under 5 miles. Check and double check this, you need several thousandths clearance to be safe.

Here is another source for a bellhousing specifically designed to adapt the ZF 5DS25/2 to a small-block Ford V8- try Bob Wood at [email protected], they have one that will work fine as well. Also I think they can supply a clutch which will go inside it etc etc. Good luck.
 
You do have to flip the pantera box so the input shaft is below the diff, also the diff has to be fliped to the the left side or you will have 5 reverse gears and 1 forward gear.
The oil system in side have to be changed to lube all parts in the new direction. Lloyd@ www.rbttrans.com

Hello Lloyd,

I intend to do that on a Pantera ZF DS25 that is being offered to me. I plan to install it in my Superformance GT40. Would RBT sell the parts to do the conversion ?

Yes, RBT will sell you the parts IF you can get them to respond! There are a couple of people who can do the conversion for you and ensure your transaxle is in condition to go behind a stout V8. PM me for references.

The ERA build manual has instructions on the minimum you need to do to and where to drill oil drain holes to flip it, however I believe RBT and Ron McCall go further than that when they convert for use in the GT40 orientation.
 
the serial number on the Pantera transmission offered to me is 4713. the part number is 1031 002 001. Would you have any idea which Pantera it cam from ?
 
Pantera ZF serial numbers do not align to Pantera chassis numbers what so ever. Nor did the DeTomaso factory record what serial number ZF they put in a specific car. And, given the fact many ZFs were blown, Ford had a load of ZFs sent to dealers in crates to become the spare parts bin for the cars. I owned Pantera s/n 1744 with was the 744th car made and it had ZF 2131 in it. I bought a used ZF last year for my 40 which is s/n 9371. The part number you site is the part number for a Dash 2 ZF. Post a picture of the i.d. tag on the shifter box.

When Ford closed out the Pantera parts program in the 80's, our Ford store purchased a lot of the inventory. We paid $600.00 each for new -2 ZFs in the crate. I know someone I sold two gearboxes to. He will not part with them. However, they had no oil or corrosion coating so if not stored in the mythical "cool, dry place" they may have pitting on the gears.

Hi Rick, you brought me way back to my youth by mentioning Ford Motor Company's Answer Man, John Vermeersch. I met John in the early 80's when I built my ERA 427 Cobra (#076). John's shop, Total Performance, was a frequent stop for me to see what hardware was there on any given day. Frequently I could see Bob Glidden's Pro Stocker, GT40s (my fav's) or just soak up some of John's vast knowledge. He could quote numerous part numbers off the top of his head and his advice helped me build the 427 FE motor with a big input/big output Top Loader 4sp. trans for my Cobra. As mentioned, John's shop, Total Performance on Groesbeck Hwy. was a great place to visit. John always made himself available to Ford fans such as myself. I had my Cobra entered in the SAAC 11 car show in 1988 (took 1'st place in my Replica Cobra class) when my car suffered some "minor" front end damage, I was devastated. John Vermeersch had to remain at the show so he gave me the keys to his shop, along with the alarm code so I could get his car trailer to take my Cobra home. This is the magnificent person he was, I feel very fortunate to call him my friend! Eventually I took my car back to ERA in New Britain, CT, and Peter interrupted production to have his body shop repair the damage. I took it back to Detroit for painting and a happy ending. Here is a photo of John Vermeersch, just as I remember him. Also a couple poor quality shots of my Cobra photographed on the Ford Estate (getting on that location for some quick photos is another story) as well as the award plaque from the show.

Your car wasn't the one that rolled down the grassy knoll and center punched Jim Wick's Mercury wagon, was it?
