I was wondering if anybody has ever heard or tried exchanging the a1000 for a 2000 or 2500 they are the same size just built heavier...wonder if they hold more power or how much...just got my mind going reading some spec sheets:D

I don't know, seems to me like even though they are built heavier don't know if they can handle more hp, because most of the larger trucks run less hp power does that make any since...... It did in my head.

Less horse power, but more torque:

Duramax LQF 2009 300 bhp (220 kW) @2200 860 lb·ft (1,166 N·m) @1450
They were mated to the Allison 3000 and 3500 Series transmissions though.

the 3060b used in school buses is a much larger tranny but is only rated for 275hp but it bolts up to a 8.3L cummins and the rpms are lower than in your truck

I'm new to this site and I have learned alot about my new Duramax reading all of the information on this site. I recently purchase a 08 3500 Dually 4x4 (and I love it), but a buddy of mine (a ford owner) said that the allison transmission is just a GM tranny with the Allison emblem slapped on it. Can any one here shed some light on this subject?

Thanks

Been wondering the same thing. It would be sick to have a 10 or 15 or however many speed tranny like a semi but doubt it would be practical.

seth idk good idea but i will have to say no just because the different hp rateings so ever thought it says 800 ft lbs tq if you build power out of your truck that will be very quick to come and go

I think the only difference is bell housings, and lack of parking pawl.

go to some of the web site for allison transmissions and you will see there is a lot of difference between the 1000,2000 and 3000 series let alone the physical size
