roast, do you mean after rev matching and then simply be in a gear at high rpm without throttle (engine braking)?
Or do you mean without rev matching letting the clutch out and the RPM need to jump up for the lower gear?

The problem is still there, just a bit less ovious than before.

Next I think I will have them check the diff. because it only happens when decelerating.

Capeland did you have your driveshaft dropped out and checked as I suggested. If the universal joint is stiff this will cause a lot of vibration through out the car full stop.

Yes and both joints were stiff and notchy. the car is smoother then before with the new shaft in place but the vibration while decelerating is still there, just not as much.

Thanks for the heads up Bronzee
