Does the tranny linkage move or stay still? Check the linkage connections.
If the connections are ok, the problem is likely internal to the tranny. Might be a broken hockey stick. You will want to replace a few other things while in there like the bushing and seal. _________________ All the redemption I can offer, girl, is beneath this dirty hood

If you are unfamiliar with the general layout of things, here is a great starting point resource so you know what you are looking at:

You likely had a CV joint come loose. Either the bolts came loose or sheared. Get new bolts and hardware and then tighten the bolts to the Vanagon spec of 33 ft*lbs. You might as well assume that all the rest of your CV bolts are loose and need retorquing as well.
You might consider buying and using some of these verses the stock Schnorr washers.

No. Not yet. The best thing to do is to have someone manipulate the shifter while someone else observes the full linkage from end to end to see if and how it moves. _________________ All the redemption I can offer, girl, is beneath this dirty hood

Lets begin with some basic stuff first, while a helper puts it in gear, releases the clutch and holds the brake you bend down and look at both the driveshafts, is either one turning? _________________ Rust NEVER sleeps and stock never goes out of style.
Please don't PM technical questions, ask your problem in public so everyone can play along. If you think it's too stupid post it here

Might be too much action down there for that, too much opportunity for miscommunication.
"Stop, the drive shaft is banging around!"
"Whaaat?"
"Stop, stop, the drive shaft is banging me, ow, ow."
"Whaaat? Do what now, now?"
How about:
Place gear shift in 1st gear - clutch pedal off - engine off - level ground.
a) did shifter seem to grab a gear? - No, check coupler, force a shift with vise grips push or pull.
b) Yes we have a gear selection, try to push car at driver's door. -
Yes car moves readily? check driveshaft integrity.
If the coupler is exploded with missing rectangular blocks, how about fixin that . . .

Well everything seemed to be moving with the coupler and everything I was able to check. Luckily a friend of mine is in a VW club and is sending one of their mechanics over to look at it. I explained what happened to him and he said its sounding like the transmission is bad. I'll update when he comes to look at it. I've done minor work before on my bus, but never involving the transmission. This one is out of my hands unfortunately ha I just hope to have it back and running soon _________________ Setting up shop from a 77 VW Bus

Three people have suggested in one way or another that you check that your driveshafts are still attached at both ends, have you checked this yet? The failure of the CV bolts is common and typically very cheap to fix. If your shifter feels normal when you try to put the tranny into and out of gear then your problem is most likely with the driveshafts. |

Are those on the sides of the transmission? Like I said I'm not too familiar with any of the transmission part of the bus, so any photos or locations would help a lot thanks. |
Yes the axles are attached to either siide of the transmission and held on by six bolts on either end. If either of the axle spin when you put the tranny in gear, PAKRING BRAKE ON PLEASE then the outer bolts are sheared or backed out on one side, while if the axles don't turn but one of the hubs that sticks out from the tranny does (the axles bolt to these hubs) then an inner set of bolts is sheared or backed out.
This is a Beetle transmission as seen from above, the lay out is the same as for a bus. The inner flanges are not very visible in the picture.

It might just be the clutch. A friend has his disc disintegrate. No go nowhere! Engine runs and revs ok, trans shifts ok??, so no power transmission. Weak links are clutch, cv's. Check them first. _________________ '72 Elm Green Deluxe |

Axles transfer power from transmission to the wheels( really from one cv to another). Really, really doubt they are bad. If an axle broke, you'd likely hear massive banging about. Maybe a cv disintegrated on the drive side, but even then you'd probably still get some movement as the cv ball bearings are huge and strong. Does it reverse and move, by any chance? I still think clutch problem. How many miles on the Tranny? _________________ '72 Elm Green Deluxe |

And can anyone tell me what part the AXLES play in this? What's their purpose and what do they do? How could this prevent me from going into gear? |
You are not afraid to ask questions so that's a great start. I would suggest reading the Muir book first and then graduating to the Bentley. You will enjoy the approach of Muir as an entry point.
