I don't know about '89s but for my '95 getting the serial number was a very clean job even on a rainy day because the transmission number is on a metal plate with a bunch of other numbers inside the bus, near the main door above the windshield.

It will take just a few minutes and then you will know what transmission is in there.

I had people tell me I shouldn't trust the guy I bought the bus from because it "probably" was a 545. I was very happy when I found this Allison site and didn't have to listen to that negativity anymore.

Good info! Thank you sir!

A lot of states have laws prohibiting the transport of children in buses older than 15 years, too.

in my opinion the AT540 is a lot better transmission than the AT545...
