What to do with my R380

[evilfij]

I don't know whats wrong with it, but something is, could just be noisey or have a slow synchro. Its out of a 98 110 from some guy from sweden brought to the US while he was here. I got it for $100.

What would you do:

My basic understanding is the R380 parts are usually too expensive to warrent rebuilding the trans.
I myself hate having anyone work on my junk, and figure if someone can fix it than so can I. Only it might take me a while(or longer) to figure it out.

So i say since you got it so cheap you have nothing o loose and would:

1st. find out how much the special tools are and which ones you actually need.
2nd. if 1 isn't cost prohibitive tear into it.

Oh an get the manual or PDF

I got the manual. In fact I read it like 5 times and could probably quote it

I am still working on the tools. The dealer said they should have them. They look fairly well necessary if I need to do anywork to the mainshaft or the layshaft. Also I hear the oil seal puller thing (which is what you need to even take any of it apart) is fairly well necessary.

I guess where I am now is that it is in one piece and it looks to be able to provide some forward progress when attached to an engine. This feature may change if I take it apart.

My experience is limited to taking apart a Series box and putting it back together (I hesitate to say I "rebuilt" it).

well then give it a good look over and try it out.

I would attempt to check for excessive play in bearings.
shift the trans into each gear.
Might not be anything wrong with it.

You can give it to me and then go get yourself a new one. That way, you don't have to worry about the headaches of working on that one and you'll be secure in the fact that I'll pull it apart, fawk it up, and then have the pieces laying all over my garage for the next 3-4 years.

Seriously, if you really want this particular tranny in this truck, have someone do it for you. If you want to do the budget route, pull it apart yourself and see if you can find any problems. And if you want one that definitely works, go see ECR or Mohammad or someone and get a new or rebuilt one with a warrantee. Then you can tear this one down at your leisure and see if you can't get it to work. Then you've got a spare or something you could sell and make some $.

I would do a combination of what John has suggested.

Buy a new/refurbished R-380 and KEEP the one you have now. Take a look at the one you purchased that is good, and kind of 'reverse-engineer' it to see what you can do to get your 'old junky' one going.

For $100 you're not out really anything, and considering the headache/hassles you might encounter, that $100 might end up being the most expensive R-380 ever built.

For example: I *thought* that it was a 'bargain' to have purchased my 80-inch truck for *ONLY* $500. That was the most expensive $500 I've EVER spent. Get the picture???

Good luck!

Yup.. what he said. I kept the LT230 out of my D90, the ZF from the rangie, and I will keep the R380 out of my D110 when the new one arrives. One: for spare parts. Two: so I can rebuild them at my leisure and figure out what went wrong with each. And Three: So if one goes out again and it's an emergency, I can send these out to be rebuilt and then have them back into the truck faster than pulling the existing one and rebuilding it. Also, I got each replacement cheaper than paying someone to rebuild the old ones. Yes, I know I can do it myself, but I don't have the time, knowledge, or facilities at this point.

So.. that's the plan.

What do you think?

no problems so far. 37s with a rimmer supercharger.. works well at this point. I guess we'll find out for sure at Las Cruces. I know I need lower gears, so I'm bringing my 35s just in case I decide that I don't want to run the 37s the whole time.
