Tacoma, WA area drivetrain inspection?

We are looking for any recommendations, tips, or advice on finding a decent, affordable, trustworthy deisel mechanic to do a thorough inspection of our bus drivetrain. I'm also looking for any options available to increase the speed above 55, at least to 65mph, that don't involve replacing the trans.

We have a 32' ElDorado National Escort RE (1997) with a Cummins 8.3c (haven't looked to see the transmission, I'm worried it's the dreaded AT545). It's licensed through Vermont, but no insurance, yet. It runs and drives, and it made a 1hr highway trip to our home with no issues (other than having a 55mph limiter of some sort). I have started it every 2-3 weeks for the past year and driven it around the neighborhood a few times. I have not monitored or maintained coolant, filters, or anything else besides the batteries (commence flogging).
I have very little experience with auto drivetrains, and none with diesels or large engines. The bus is on a gravel pad on the side of our house, and can be easily-accessed and/or worked on where it is. I can also drive it to a shop, if it's not too far to go (the tires are old and worn and I don't want to get stuck without insurance on the side of a road or worse).
Any constructive advice or so recommendations is greatly appreciated.

If not changing the trans, which is the first thing I would change if it is a 545, the only option would be to change the gearing in the rear end.
I would guess with that motor, you likely don't have a 545.

Google search "Tacoma Wa. diesel repair" There are a few places that could handle an inspection.
