The older 3550/TKOII's are not related to the new TKO 500/600's. In 1995, the 500/600 weren't available, so most likely it's a 3550.

If you could find one of the TKO II's, they were rated for 425 lb-ft of torque. Here's the thing about torque ratings. The TKO's are rated in continuous loads of torque. So if they'll take 425 or 500 or 600 lb-ft, they'll take it all the time. That means that they're pretty stout trannies.

A Cobra is a very light car and if you run street tires, the tires will break loose before it hooks up and breaks parts. For a street car, you can get away with a little less transmission.

TCRIST,

The older TKO2 trannies were available with a 26 spline input shaft....they are in no relation to the newer boxes.
