I get banging noise over bumps. Its seems like car has been dropped from some height. If I go slowly over bumps then nothing comes and even suspension works perfectly fine but this noise comes when I driving little fast. Even I can feel the small hairline as well.

One major thing i can tell... While opening the pan to remove oil and clean transmission filter, mechanic jacked up the transmission
to remove all nuts/bolts. But after that i have replaced transmission mount. Any other connections that needs to be replaced that connects transmission to chassis. But how to diagnose this problem.

For this issue I have replaced sway bar bushings, new engine mounts left and right other two are good. Other control arm bushing also checked and looks fine. Then strut mounts replaced, then shock absorber also replaced. Even endlinks, ball joints are also checked. But still sound comes. it sounds like gut gut... over bumps... I dont know if I need to replace springs something else. I dont know. Please let me know what all can I check..
Its Nissan Teana 230JM 2007... 80k kms driven.

Ok... Sounds like you hit most of the usual suspects. How about the battery being loose?

No, thats perfectly placed... is it possible that transmission is banging.... as the mechanic jacked that up to remove the transmission pan...

Yes I have replaced transmission mount and right engine mount.... any other connection of transmission to chassis apart from that mount... ?? Or the transmission is tied on that mount only... ?

Torque strut mount? I only say this cause my '11 altima has a broken one I have yet to replace and sounds similar to what you described

Is the strut mount center bolt torqued down to the strut mount properly? Make sure they are tight with weight on car. Also, have checked away bar end links?
