Default Viper T56 and 5.3

What would it take to make a T56 from a dodge viper work with a L33 5.3 gm engine?

I am asking because I can get a good price on a viper transmission but is it even possible for it to work with my L33?

Thank you

Everything front plate forward is Incompatible as it is.

The input shaft would need to be changed or modified. Other have swapped in a GM input shaft.

The Throwout bearing would have to be change, it is of a different bolt pattern to the front plate... you can swap in a GM one or mod a GM Throwout bearing and make a spacer (.500) as the Viper one is shorter and also a larger inner dia.

Bell housing will bolt up to a Viper Plate.. But I suggest swapping it for a GM one.. that way you don't have a one off Bearing and have to mod the new one once the current one fails.

VSS sensor is a different size, pigtail and most important .. signal, which is not compatible with the GM PCM input.
