allison
 

anyone know if the six speed allison bolts up the same as the five speed allison?

yes they are essentially the same trans with valve body changes and different tuning

just different vb, torque converter, wiring and tcm with the 6 speed trans.

bolt patteren the same

Does that mean you could turn a 5 speed into a 6 speed?

yes

SWEEEET. :humm:
If I come across a wreck, I might have to pinch some parts.

you can also get a kit from Suncoast but its expensive :ouch:

no...if you want to make a 5-speed into a 6-speed you HAVE to get the suncoast kit...

a factory 6-speed TCM will not work with an 01-05 duramax in any way.

The only way to get 6-speeds in an 01-05 dmax is to get the suncoast stol-I mean custom TCM. :U:
