Sv6 black edition 2016 clunk noise

[Jasonjohn]

Hi all, recently I’ve been noticing a clunk noise when shifting gears from reverse to drive, a clunk will form from the gearbox. I have a sv6 black edition 2016 ute. I’ve also been noticing a similar type noise while driving at low speeds hearing a clunk/tap when letting go of the accelerator. & then when I hit higher speeds of 60-100km I’ll hear noises something is spinning/ gurgling seemingly under the gearbox. What could this be? I’ve gone to 2 mechanics both have failed to diagnose a noise.

Could be tailshaft. How many km has the car done? I would suggest you take the car to a transmission specialist.

 

[Jasonjohn]

Tailshaft checked and all good apparently- 160,000kms

 

[Sam_100]

Has the transmission been serviced yet? The maintenance scheduled recommends it be serviced either at 150,000km or 90 months whichever interval occurs first.

Hasn’t had a transmission service yet at 160,000

It's the tailshaft flange on the gearbox. The flange has to be removed, cleaned up and refitted with Loctite on the splines. There's a Service Bulletin with the full procedure to fix the clunk.

How much would that cost to do? Would a regular mechanic do that?

Yes, most mechanical workshops should be able to do the job.

This is a video of the sound, I’m letting go of the accelerator very quickly on and off to amplify the noise of the clunk
