    I was driving and my van just stopped. No transmission anymore. There was a big noise underneath the chassis at the back, and I could shift the gear, engine was still running.

    I tried to any gears (Reverse and the 5 other gears), nothing. When I engage any gear, it does a pinions noise, light noise.

    I reckon something is broken in the gearbox.

    So I need a mechanic good with transmission for this sort of models. Do you recommend any in West Melbourne (Living in Williamstown) and also some towing service not too expensive.

    Thanks, Seb.

    Check under the rear end and make sure you haven’t just dropped a drive shaft/ cv has become disconnected.
    Easy fix……just bolt it up again……if you can find all the bolts.
    Or, RACV should get you a free tilt tray home.
    Cheers,
    Mark

    In addition to Mark's suggestions above, check CV joints etc that were replaced recently to get your roadworthy.

    Far out, you were right. The bolts were not tightened enough on both CV joints (Right and Left).

    I can't believe it. My regular mechanic (Also listed in "Vintage VW SOS" app, Power House Motor in NEwport, 5mns by walk to my home - this guy is brilliant and old school, I use him for my 2 cars for years), double checked the work of the previous mechanic I used for my RWC, and fixed it up.
    Will cost me 500 AUD including the towing... I am so p*****.

    I would say I am relieved it's not the gearbox but still...

    $500Aud was that just to tighten the CV bolts or is there other damage caused.

    You have to remove the wheels, remove the braking stuff, and you get 4h labor... 2 bolts were snapped. That's it.

    Are T3 bolts triple square like T2?

    Is the cv/axle junction different to a T2 ?
    If not, I do not understand why all that work was required to rebolt the cv’s up again…..o_O

    Bah, I used another mechanic, because I don't trust the first one anymore.

    You are right;

    I could have done it myself actually for free...

    He didn't have an hoist available for my van neither, so maybe the access isn't as easy when you no access from underneath.

    It is……
    I’ve done mine roadside after an experience like yours…….
    Oh well, it’s all a part of the learning experience……..just a bit more expensive than it needed to be.
    Cheers,

    They are exactly the same CVs and axle to a T2.

    Thanks Phill, I was trying to work out why the “mech.” in question felt it necessary to remove the entire rear wheel system to work on a couple of cv bolts…….I thought that maybe there was something different between a T3 and T2 rear end……obviously not.;)
    Cheers,
    Mark

    Perhaps the mechanic isnt able to extract the broken bolts with the axle hubs in place. I would have thought it could be done

    Did he let you know that it would take 4 times as long without a hoist, and cost 4 times as much, and offer to rebook the job at a time a hoist was available?

    To be honest I am not bothered to have given this mech some money. I trust this one and he took my van straight away. He always serviced my cars at a reasonable prices in the past.
    Victoria businesses are plagued with bankruptcies so if it helps him during those hard times, I am happy. I discussed with him, and its quite hard for them at the moment, nobody drives.
    Really, it sucks here. By the end of lockdown planned in November, we will have 4 months lockdown. I cant imagine the stress for those guys.
    Anyway, I learnt what is the differential today and how to fix CV joints! :)

    The CV's are enclosed in the lower arm which limits access to the broken bolts which makes them hard to remove particularly if they have been loose for a while.

    Thanks Les, I was wondering if there was a difference in the setup, to a T2.
    Sounds like another (non) improvement through the models…..:rolleyes:
    Cheers,

    Sorry Mark I missed the important point which is the change from torsion bar to coil spring suspension which changed the lower control arm and enclosed the CV joint in the arm.Cleaning the bolt recesses before trying to undo or tighten them can be a bugger and it is common to have the allen/splinesocket slip whilst tightening them.
