Default Knocking when on and off throttle

hi all , when driving relatively slowly I notice a clonk each time I press the accelerator? It happens when I'm coasting then apply the throttle , if I release the pedal then back on it it happens again. The motor mounts are new and haven't changed the symptoms. It sort of Has a hollow sound to it . The cars a Euro s 1983 model .its an automatic . Any ideas ?

If Volvo then the fingers may be touching

Vibration damper inside the torque tube shifting? Clunk when braking, clunk when accelerating?

a thunk just after you come to a stop would be what Sean said.

My clunk is only when I accelerate. I dunno why. But I know for sure my clunk is the vibration dampener inside the TT.

Mine is slapping for and aft like crazy. Going to wait until it pounds the bearings out the front and rear and then just rebuild the thing with Constantines bearings.

I already have a 928 Intl rebuilt ready to go in, but I just have to find the time and facilities to do it.

Bods,
There is no quick fix per se, but it's a most of one day job normally. Less than that if you've ever done it before, you have access to a lift, and already have a rebuilt Torque Tube.
