millenials RV bus conversion

We are a group of millennials from Alberta Canada converting a 1997 GMC Bluebird 54 passenger with an eaton 5sp manny tranny and a cat 3116 diesel. Everything but the engine has 350000 kms on it but the engine has 50k.

It's our first time doing anything like this so any tips and tricks are appreciated.

Also it pops out of 4th gear. anyone know what I could do to remedy that?

Nice bus and a good project for a group of enthusiastic millennials.

Maybe someone in the group is a mechanic? You'll need to remove the top cap off the transmission, then repair the detent balls and springs. It's actually pretty simple but it's also important to get it right or the transmission won't shift. The shift forks have to go back into the right positions when the top cap is put back on.

I trained as an aircraft mechanic but aircrafts contain no transmissions. I also know nothing about diesels. Are there any resources or maintenance manuals available online or should I order them?

Here's a link to a service manual, however, it doesn't give any repair info in detail.

I actually ordered the OEM book off ebay for my motor so I have the specs for everything. (I plan on rebuilding another motor for a back up when I have time.)

I've found operator's manuals and parts manuals free online. I doubt I can find any exploded view of your transmission. If you're working toward being an aircraft mechanic this should be pretty simple.
I'm worried that you won't get the shift forks back in the correct position during reassembly if I explain how to take the top cap off the transmission. It's likely you'll have to go to a transmission shop to get the detent balls and springs changed, but that repair will stop it from popping out of gear. Do you want to try it yourself?

You'll need to remove the floor over the transmission, which should be self explanatory. Once you can see the top of your transmission you'll notice the top plate bolted down right on top of the transmission which contains your shifting mechanism. Simply remove the top plate bolts, then carefully lift the plate so you can see the position of the shift forks, because you're going to need to get the forks back into the same position as when you removed them.

You'll probably need to take the top plate to a transmission shop to get the detent ball and spring replaced unless you can find those parts yourself. The detent ball and spring are what holds the transmission in gear. Sometimes the spring breaks and other times the detent ball becomes so ward that it just falls out of place.

During reassembly it should be immediately obvious if the shift forks are not in the right position because the transmission won't shift correctly and you can feel it.

After those little parts are replaced, and if you can get the shift forks back in the proper positions, bolt the top cap back onto the transmission and replace the floor.

In theory that should do it. It's never clear following someone else's instructions. I haven't worked on that specific transmission but manual transmissions are pretty similar.

Sounds like a fun project for a group of friends.

Just out of curiousity, how many of you are older than the bus?
