It is kind of an odds thing. I doubt the donar car was scrapped for a bad manual transmission. The worst on a really high milage example is usually worn syncro rings. Still they are not generally scrapped for that either. You pretty well have to put the box into service to find out if they are all good but they probably are. Great time to change the oil as well.
As I stated its an odds kind of thing. If you pulled ten of these manual transmissions out at a yard. Nine out of the ten would probably still be good. The odds are probably somewhat less on their automatics.:D

I'm not always so optimistic, but I would think that you would have to statistically pull more than ten to get a bad one.

There are really on two things that would get one of these things, outside of someone draining the oil and forgetting to fill it up again, and that would be a hydraulic problem that was not attended to in a reasonable amount of time or someone being intentionally abusive to it.

My $0.02,

I'm about 75% done uploading it to vs-tech's server.

Lance, thankyou and thanks to everyone else who responded. A junkyard I know of has a pile of trannys in an old shed and a few of them are mb 4 speeds. There covered in dust, been there along time but maybe there still good. Are parts available to rebuild one and if so are they cost prohibitive?

for what they cost and their ruggedness, it would be more sensible to just go get another one in the very unlikely event you got ahold of a bad one.

I wonder what most people are paying for there conversion parts?

I posted a thread a few years ago on my costs. I pulled everything out of a 240d at Pull and Save that had been wrecked including pedals, clutch, flywheel, driveshaft master cylinder and tubing. I think the price was under $150 for everything but I'd ask more than that if I wanted to sell it.

I rebuilt the Laycock de Normanville overdrive in my MG a couple of years ago. Having never worked on something as complex, I was eager to test it before I installled it. I talked to a British car mechanic friend of mine who said we could send it out for testing, which would have cost about $300 including shipping, or I could take my chances.

I took my chances, installed it, and it didn't work. I had to pull the engine and transmission again, and was able to fix it correctly the second time. After so much experience I was able to pull the engine/tranny in a couple of hours.

My point is that even if you have a bum one, it's not that much trouble to pull it out again.
