The newer Allison 1000/2000/3000 series of automatic transmissions are all electronically controlled and have at least one overdrive gear.

With 5.57:1 gearing you should be able to cruise at 60-65 MPH while still having the ability to get up hills without losing too much speed.

If it isn't a newer electronically controlled automatic transmission it is most likely an AT540 or MT640 series of transmission that has four forward gears with the top gear direct drive.

Direct drive with 5.57:1 gearing is going to have a top speed of about 50 MPH.

If the bus is generally the size you want I would say go for it.

The availability and location near you makes the price very attractive.

Just make sure than any rust is superficial and not cancerous.
So they gave me another update on the trans.

"This bus has an Allison 2000 series and the govner is set at 99. It also has a turbo."

It may have the governor set at 99 but I seriously doubt it can go that fast.

The Allison 2000 series is a good medium duty transmission with 5-forward gears with 5th an overdrive gear.

Well I can tell you that I'm not going to be the one that takes it to the 99 mark. I like that its a good med trans. Not after fancy or show off just do the job good. Thanks for the info. I'm hoping week or so go get it. The plan anyway

I have heard good and bad. Was told usually 150,00 was the life of one and start tanking just before. Any truth to this?
Thank you

maybe, depends on how they are looked after, I know of 4 of them in my town that have over 400,000kms I have 226000kms on my mine, I replaced all 8 fuel injectors on mine last spring, really woke up the old girl.
There's lots of ford trucks that have 300,000kms on them.

I do know this bus was a trade in (up grade) for the district. I was hoping that it was maintained good because of the cargo. We have been short handed at work so still haven't had a chance to get there to look at it my self. Hopefully this week treats me better.

If it's the same engine as the 7.3 turbo that's in my truck, then you will have a good engine I have 375000 right now..runs good but could use so injectors.

Just wondering where in Oklahoma do you live?

300K miles in a school bus would be about the most one could expect out of that engine. They really start to get tired after about 285K miles.

At 150K miles, if the bus has had decent preventative maintenance there is no reason to not expect the engine to double those miles.

Of course along the way you will most likely need to replace injectors. For sure you will need to replace the glow plugs.

Those engines will start with as few as four working glow plugs. But any fewer and the engine just doesn't get enough heat up into the combustion chamber to get things going when the engine is stone cold.
