[DeTomaso] Different Transaxle

[Tomas Gunnarsson]

Julian,

Is the ZFQ you mention this transmission?

I personally don't believe the RBT 6 sped offers any great advantage for
the cost, especially as a tall 5th upgrade to your existing ZF achieves
the same thing, as 6th in the 6 speed is that same gearing, just one
more shift to get there. I upgraded to a tall 5th and the rpm drop from
4th to 5th is not excessive, considering 5th is an overdrive for
cruising. I'd invest my money in a 3.77 ring & pinion long before I
considered a 6 speed.
 
As alternatives to the ZF you can turn to the mid engine kit car guys
for inspiration. Many use an inverted Porsche transaxle with the G50
considered one of the best, but to build it to withstand 600HP takes
money (the G50 I have in the Ultima came in at close to $15K all in).
The ZFQ was seen as a cheaper alternative to the ZF (and came about when
there was a boom in the GT40 kit car market and a shortage of ZF's).
There are reports of ZFQ units having suffered catastrophic failure when
used in anger.
 
The Ricardo is a good transaxle, but doesn't fit in a Pantera without
major modifications and is no longer supported so spares are becoming
rare. Ricardo's were selling for $6500 at one point, you'd be challenged
to find anything under $10K currently I think.
 
Most of the other transaxles available are pure race car stuff, very
expensive and short design life spans.
 
In short the ZF really takes some beating, in both senses.

Cory, the one and only reason I can see to change tranaxles is for an
overdrive 6th gear for fuel mileage savings on long trips. If I could
afford it, I'd use RBT's 6-speed upgrade for the ZF which I know fits
everything.  The powerful 351-C doesn't need a close ratio 6, 7 or 8
speed gear cluster, and zero other transaxles fit a Pantera without
major work.... then you have the shifter & halfshaft adaptions and maybe
useless electronic do-dads on 'modern' units to contend with.

If there was a modern, smooth, non-ZF transaxle available for the
Pantera that 
fit without major rework would anyone consider switching?  What would be
the 
biggest reason, if there are reasons?  Are you satisfied largely with
the ZF 
transaxle in your car(s)?
