Jim is 100% correct, DONT mess up your virgin tranny, none of the shops will
ever build it like the factory did, I have a rebuild in the 71 now and its
noisy and stiff.  It takes alot of time and knowledge to get the trannies
right and few will do that.

I got 298K out of the original tranny in the 71, and I towed with that too!

as for limited slip trannies, the one in our 79 grand Prix was still doing
its job at 135Kmi, but as I remember they needed a special additive to the
hypoid oil, smelled like rancid piss.

If I were you, my peace of mind would be better off if I never let this
get out of my sight. The problems you mention below are pretty simple ones 
that it sounds like you should be able to fix yourself. I'd leave the inner

if you actually have a bent axle, find a replacement. If it's just a dented
tube, ignore it, straighten it, or replace it.

Those are all easily fixed/replaced by yourself. Since you've gotten this
it's pretty clear that you have the ability to do this work yourself. The
part was getting the outer bearings off the axle shafts, and you've already 
done that.

If you do all this, consider replacing the rubber boots over the inner ends
the axle tubes. Since you've got everything apart, get the seamless OG 
versions, not the ones with the joint.

Mod? What was done? If it's just paint, ignore it. If someone else has 
already taken this tranny apart, then maybe you should look for another one,

preferably a virgin, but keep in mind that the gear ratios in Type 3 MTs are

different from Beetle MTs. You'll find lots of people eager to sell you
MTs, and a few people who will tell you they have Type 3 MTs when they 
don't, but real Type 3 swing axle virgin MTs will be harder to find unless 
someone on this list has one to sell you.

As for cleaning, there's a local truck shop here that is willing to steam
trannys for me if I carry them in. Perhaps you could find one near you, but 
keep the water out of the inside of the tranny.

Consider being a pessimist also about the quality of work you can expect in 
a transmission rebuild. This is VERY specialized work that requires several 
thousand $ of unique tooling to do correctly. Anyone who quotes you a 
"reasonable" price either isn't planning to do it right, or they don't know
they are getting into.

They are in the parts list, but I've never heard of one actually being
I suspect they are like ATs in 914s; they are in the parts list, but they
really exist.

I just watched an interesting video on YouTube about different kinds of 
limited slip differentials. It was interesting and informative. One thing I 
learned is that the common types wear out in about 20k miles, so they 
become standard "open" differentials. Watch this, he gives a very good 
explanation of the various options. I learned a lot from this, although I
if most, or any, of those options are available for our trannys.
