Hi All

So Here's what I know and don't know

I Ran the bus up on blocks and blocked it up, and three of us looked for the data plate. We all agree, we see where it should be but there's nothing there

I reached out to the company I bought it from and they are pulling records to see if they have any notes on what trans is in it. When I bought it, the gave me all the maintenance records from the day they bought it but no mention of what transmission it is.

As an aside, Its hilarious to read the mechanics comments about the drivers. Its a comedy show waiting to happen

Back to the bus Here's what I get from at road test . I haven't gotten the bus out to my hangar yet to verify the tach so these are the numbers that come up on the tach but nit verified yet.
