If you want an auto an MT643 is going to be your best bet.

my vote is for a 10 or 13 speed eaton, spicer, or fuller transmission with overdrive and a new conservative set of rear gears.....and a hydraulic clutch, lots easier than trying to run all the linkage i would think.

The MT643 is a 4 speed auto just like the AT545. Fourth gear in it is a direct gear, but the torque converter locks up unlike the AT545 making it slightly more efficient. It is also stronger than an AT545.

The RTO6013 is a big overdrive 13 speed Eaton that's been out of production for a while, but was and still is popular, especially for people doing conversions because it was a single countershaft model making it narrower than many other medium duty truck transmission.

Re: best trans for dt466

i've never actually driven a bus with a manual trans, but i've driven a few large fire trucks with standard transmissions. I think that a manual trans is prob not good for resale value because it's more work to drive, but the increased fuel economy, and the increased road speed seem like they would be well worth the increased driving effort, not to mention i like shifting gears.

here's my idea of the perfect setup: having like a 3.73 rear end (if you could find one, 4.10 or 4.44 might be the best they make, not sure.) and a 10 speed trans. Even if you didn't have enough hp to use gears 8,9,10 on flat ground, that's ok because you could find the gear that keeps the engine in the most efficient rpm range. When you go downhill you can use the top gears for increased ground speed which will help you climb up the other side of the hill. I don't know if you can find overdrive with a 10 speed, or if you have to upgrade to a 13 speed.

i read a story somewhere about people delivering brand new crown buses to school districts and having to drive over the mountains. The crown buses with 10 speed transmissions would arrive like an hour or two before the 4 speed models of the exact same weight and hp ratings.

Re: best trans for dt466

Even though I'm not as smart or versed as Jason lapeer in the mechanical aspects of this stuff, I definitely agree with his trans desires. I just recently inherited a 98 Subaru and it is the first auto trans I've ever owned. I too like shifting gears and once I save some more dollars I'm going to start looking around for a new rear end and standard trans for my bus. It may not happen, but I'm going to look into it. I've still got that bus with the DT466 and MT643 and even though I would like the dollars for the bus I'm working on now, I just can't let it go.....yet.

Hi Jason, Yes, you can get a manual 10 speed with overdrive. In the Crown world, it is referred to as an RTO 910, the O in RTO is for over drive. Hopefully, when I get my bus on the road, I'll be able to see if I can buy an overdrive transmission for it. It would be a lot easier than changing the rear end, it's also cheaper.

Re: best trans for dt466

is there an overdrive unit option for the mt643? lapeer what do you think of an AT545, which i have, and a 433 rear ration, which the junkyard has.
thanks
