I know one is a 5spd and the other is a 6 speed. The TKO rates out at 650 hp and the T56 so im told is 450hp. How much hp can the T56's handle that are in the Cobra's? Whats the difference between the T56 in a Viper and the one they put in the Cobra's? Im just curious and couldn't find squat on the web.

 

The Cobra t56 has a 10 spline input shaft, which is known for breaking. The viper t56 has a 26 spline and a hardened output shaft. Other than that I believe it's the same exact transmission.

If you brought a Cobra t56 up to those specs (26 spline and hardened output shaft) it'd be nearly indestructable.

 

this will not be the answer you're prolly lookin for ...

i had a t56 in my 99 cobra ... it had houston performance heads, hp custom intake, etc ... solid rear axle w/4.10s and on the 150 shot i put up 511rwhp.... i never had any problems ... fwiw

 

find D & D in Wixom, MI...they sell T56's and i'm sure they can tell you all the specs ratings..ect
