stock tranny and rear question?
I have an 08 2500 HD, D max. i have removed the compleat exhaust, k and n, removed the air foil thing, and a ppe programmer (race one with dpf set up)
my question is, what kind of power will my stock rear and tranny take?
i run it with the 125 in it usually but want to put it up a bit but i was a little scared. i plow with it, but very light with a 7.5' snow way clear plow. i just do my driveway.
in the winter i pull a claim shell with 2 sleds just about every weekend and in the summer i pull between my 5,500 pound boat or my 10,000 pound car hauler. i tow the car trailer 50 miles each way to the track, thats it. the boat i tow 5-10 miles once a month, maybe a 200 mile trip north to a poker run 1 time a year.
i change the external filter on the tranny every other oil change (about 6,000 miles. i do the internal and a flush every 12,000 (i have the dealer do this as they have the fancy flush machine to get all the old fluid out and i know the guy so its only $80 for both filters, flush and put back together)
rear hasnt been changed yet. going to do it at 25,000 (about a month)
what do you think? can i run the 225 tune up?
thanks for any tips.

Those rear ends are pretty stout, you shouldn't worry about that.
As for the tranny, if you want to turn the power up, especially with weight behind it. Then I would look into the ATS Co-Pilot. When you start to crank up the power over 100hp with an Allison, it will eventually start to slip. Mainly due to the fact of the low line pressures to the C3(5th) clutch pack. Line pressures get into the 80 PSI range at WOT, which isn't good at all. Once it starts to slip, its going to go into limp mode. Once in limp mode your not moving. Usually the first things to go are the C3 clutch pack, or the TCC clutch. The Co-pilot will extend the life of the tranny greatly, and I would recommend it.
