Default Tranny Shift Point Question

I have posted in another thread that we just purchased our first diesel pickup.
A 2005 RAM 2500 Quad w/ 5.9L Cummins Automatic

Maybe I am not used to the shifting of a diesel auto trans, but it seems that when you get on it a little bit from a stop that the tranny shifts too quickly from 1st to 2nd & 2nd to 3rd.

It does not slip at all, actually shifts nice and firm, just that the shift points seem quicker than a gas setup.

Does this make any sense at all???

The fluid is full and clean, not burnt at all.
Thanks

Well thats good to hear, I was getting worried

Yeah I swear the shift points seem to be within 5-10mph of each other. I will have to pay attention to the actual mph.
Freaked me out, I am used to the gas engines rev right up and shift points are spread out more. Must be a diesel low end torque thing???

BTW Happy New Year, Best of Luck in 2010, and Thanks for all the Help!!!!
Already looking into the Edge Juice w/ Attitude and maybe an exhaust...LOL

As long as it's not hunting back and forth, like it's searching for gears, that's normal.

Diesel's have a much narrower efficiency range than a gasser does and the torque is all the way through the band, so the engine can operate at a much lower RPM.
