Christopher,
'only you can make the choice where you buy a bus.. keep any and all options alive.. and the more time you can take to find a type of bus that fits your needs and also buses to look at then the better informed and more likely to score a good deal you are...'
I like your line here, very true indeed! I'm just gonna keep reading, looking etc. and something will show up...
Thanks again guys for all your awesome replies!!

Hey Steve,
Short answer on the transmissions:
545 - 4 speed, no lockup, no overdrive
643/647 - 4 speed, lockup, no overdrive
2000/3000 series - 6 speed, lockup, double overdrive. However, most skoolies have 6th gear disabled leaving you with a 5 speed overdrive. Some have been successful with getting the 6th gear unlocked. I am working on that for mine.
Will have to do some more reading since your explanation is still confusing to me, but that's ok. Lots to learn indeed!
Thanks so much!! I very much appreciate it!

I wish I had been thinking earlier. Somewhere today I saw a 5.9 equipped bus for sale in Marysville, WA.
Look at today's posts and you should find it.

I found a bus, but is located in Everett, WA. Not sure if it's the same one you saw, and I did send him .a reply just a minute ago

I'll try and add some clarity:

The transmission models above (all allison transmissions) are either 4 speed transmissions or 6 speed transmissions.

I school bus applications with a 6 speed most manufactures set the transmission up so that 6th gear is not available effectively leaving you with a 5 speed.

Some transmissions have a lockup torque converter. Some do not. Having a torque converter that does NOT lock up has some disadvantages as the converter is always "slipping". This causes a reduction in top speed and a loss of fuel economy. It also generates additional heat in the transmission.

Some transmissions have an "overdrive" top gear and some don't. Having overdrive is good for improved highway fuel economy and increased top speed. Note: If you take advantage of the higher top speed it can reduce the MPG benefit.

In a perfect Skoolie world you would have more gears, overdrive and a lockup torque converter.

In the real world the closest we come is the Allison 2000 & 3000 series transmissions (2000, 2500 and 3060).

Clear as mud?

Ok, that makes sense now. I like your version of a perfect skoolie world.
There sure is a lot to learn, and I've only scratched the surface...
Thanks so much!!

to confuse things if you buy an IC 'BE' body stryle bus you get an allison 1000 transmission... its also a 6 speed with 6th gear "locked out"

Welcome! I'm new, too and also in Ohio. It will probably be a year before I can afford my bus so I'm looking forward to seeing your progress!

Weight of bus?

Hey guys,
It looks like a bus weighs around 30.000 pounds, (considering we get a 40') so I was wondering how much it weighs once it's finished.
And is there a total amount that one should not go over, as to put not too much stress on the engine etc.
Thanks!!

Wim
