Is the 31 spline T-56 Cobra R transmission stronger than the 03-04 Cobra Transmission?

Hmm ok. The 03-04 Cobras' don't run 31 spline input shafts though, do they?

Wow only a 10 Spline! No wonder everyone making high HP with those cars upgrade to the 26 Spline.

Thanks for the info guys!

Delay - But no I don't.. YET I will be getting one very soon, and there is one on here for sale with a Cobra R Trans on it and I was wondering the difference.

Thanks

10 spline input (clutch) shaft and 27 spline output (DS side) shaft (terminators)..apparently 31 on the cobra R

yes the 10 spline input shaft is being replaced with a 26 these days.
you can see clutches being offered 10 spline or 26 spline.

Aftermarket T56's generally uses 31 spline output shaft. It gets confusing..this is why ford racing sells a "terminator" AL DS that is 31 splines...

I`m looking for a 03-04 Cobra t56 transmission, I appreciate any help I can get.

put a wtb ad in the svtp marketplace forum.

try ebay...also call any mustang shops around..guys are always upgrading.
but it will not be rebuilt...there are several rebuilders online

without a core probably a rebuilt one would be $2K...with 26 spline input shaft $2.3K ..abouts
