Hi folks,

I'm new to the site.

I drive a 2007 Superb 2.5 automatic. I now find that when I put my car into reverse, the car shakes violently. Someone suggested that it could be a problem with 'sheared rivets?' in the gearbox and that there are replacement bolts that I could buy to repair this problem.

If anyone is aware of the part number for these bolts, or another reason for this problem, I'd be most grateful if you could let me have some details etc.

Thanks.

The "sheared rivet" problem affected the fixing of the final drive crown wheels in some VAG transverse gearboxes. There was a mod kit involving the fitting of bolts, but you would have to be very lucky to be left with a salvageable gearbox after rivet failure.

As far as I know, all the inline manual transmissions have bolted crownwheels and give no trouble. The auto transmissions are a can of worms though - the torque of the diesel engines makes a very good job of wrecking them, which is partly why the DSG was developed.

See a reputable independent auto transmission specialist - but the news is unlikely to be good.

I was thinking one day when my auto tranny packs up to fit a manual gearbox instead. Is this a financially viable thing to do - or technically feasible without too much hassle/welding etc. If one had a donor vehicle from the breakers, in theory all the bits should be available and relatively cheap - including the gearbox. The ECU might need to be reprogrammed though by a knowledgeable person. Would the driveshafts need to be changed, or are they identical between auto and manual cars? Do auto cars have clutch pedal anchor points/holes in the cabin? Might be far fetched as a question, but someone here might know the answers to these questions and give a view on the extent of the "project" that this might present to be!

Anything is possible and the shell/bulkhead is the same for both transmissions. You would need lots of parts, including a complete pedal box.

A real pain will be programming the engine ECU to operate without the transmission controller on the CANBUS - no doubt possible but a lot of work.

Really not even remotely worth the effort.

Looik at the mounts first, red dye stain indicates a failure. hth.

Thanks! Now I know where I stand.
