roughness on decel

ezCrusty · 03-30-2003, 03:48 AM

Anyone else notice that on throttle-off deceleration from 100-90km (65-55 mph) the driveline feels rough?
Silky smooth until you decel (eg slowing for an off-ramp) then between 100 through 90 I feel somethings not right.
Curious if it's just me, or if anyone else notices it / has had it addressed.
- Thx in advance.

If the "roughness " occurs as you decelerate through about 3000 rpm, it's probably the flywheel as described in the TSB in Denny's post. It is easiest to feel in high gear, but will be felt in all gears to a lesser degree.

Try to get them to replace the clutch along with the flywheel - that's what Sonnen in Marin, CA did for me. Others have just had the flywheel replaced and still had problems.

....you'll see that the dates there stop in 2001 or so. I've posted some on the yahoo audittowners group in the "file" section in pdf format. Also, I have a subscription to them and post here when it is relevant to the TT. Haven't been any earth-shattering ones lately.
