94 or newer with DT466?
After quite a bit of reading i am settled on a 94 or newer bus with the aDT466 and with luck a Allison 545 tranny. I was thinking 94 or newer so the rear brakes will be auto adjusters. I am wondering what i should be for year wise.
Weren't there DT466'S in buses until 97 and then totally DT466E. No E for me!
What rear gears did they come with? I want to be able to do Yellowstone coming from the midwest. I don't need major speed on hwys or Mts.
I have read a bit about the rear ratios in some threads
Thanks for looking

My 92 has auto slack adjusters.
The 545 would be my last choice. Especially for mountainous regions.

As I understand it the 545 won't provide much in the way of deceleration going down a hill, so it's all brakes. I would prefer a different transmission...

I'd be surprised if you found a 545 behind a dt466. Even in there lowest torque rating they're still too powerful for the 545. I'd Shoot for a 4.80 or there abouts for a rear gear. That will give you decent highway speed and quick enough acceleration too.

I've seen plenty of 466's with the 545's. Especially FL buses.

Really? Huh, how 'bout that. Next time you see one let me know what torque rating it has.
The lowest I've seen was like 550 ftlbs which is a bit over the 545's capacity. I wouldn't think they would do something like that.

I know I've seen em. My 195hp DT is rated at 520 ft-lbs but I think they made DT with even lower #'s.
I've been wrong before, though. Happens all the time.

Well lots of em came with 643's like mine. They're stout and function great. They don't have overdrive, though. Fourth gear is 1:1
They're great, though.
The newer OD units are awesome, like the 3060.
When I was bus shopping I was looking for any big, reliable engine with any transmission except a 545.
I mostly looked at 466's and 8.3's. The 466's are more common and I ended up with a 466 and 643. Great combo and simple.

Going back to something the OP said, don't let yourself get hung up on slack adjusters as a fundamental buying criteria. This could be (relatively) easily upgraded so if you find the right bus otherwise don't let that sole point cause you to pass it up.

What years are we looking at for the 3060?

Like EC said, there are plenty of 545 behind DT466 engines. I own one and see them on the auctions all the time. Mine is a 1997 Genesis with a mechanical P-pump motor rated at 190hp. I also have a 1995 DT408 with a 545 behind it. I don't know the torque specs. I think at 210hp, you will see the 643.
