they have the same shift pattern. im not sure about ratios as such. the shift towers are different along the shifter itself. im pretty sure the bellhousing is different between the two as well. in other words, dont look for a powerstoke zf to swap into the dmax...im just not a fan of auto's because i will kill them and dont get me wrong i love allison but its an auto and i will kill it so i found an article on the manual it said that this is the same 6 speed that is run in the powerstroke is that accurate?
I was thinking i would like to get a auto? I have a 6 speed . Its a 2003 gmc. It has the double clutch plates. Stock clutch was shit. There is only 72000 miles on it.i would like a 6 speed manual in my 03 GMC and my question is how hard would it be to swap out the allison for the 6 speed? does the ECU need to be changed and what modifications would need to be done to make it work?
It is the only auto that has ever been hooked to the Dmax "trucks". The vans got the 4l80e behind them.when did the allison come into being for the duramax in the 25/3500 series?

I have been told by numerous people, that I should have got the 06 and up, as then it would have the Allison. Most people think that because the 01-05's do not have a Allison badge on the door that they did not have the Allison trans matted to the Dmax.
They seem to think we have the 4l80e, and then I ask them, since when did the 4l80e came in a 5speed version
