Hey guys new here and would love and need feedback here...I've always had a small whine when on the accelerator ..thought was O2 sensor but no light mechanic says sounds from transmission, read online and found it's pretty common among acuras. But always had me worried about my transmission so trying to listen to every small noise I notice it shifted a little harder in first couple gears but nothing crazy now if I'm parked on a down hill driveway that's steep and I put it in reverse it shifts pretty hard..but nothing crazy...I just recently install coilsovers myself pretty easy but now I'm feeling a Strong vibration while accelerating immediately off when off the accelerator...weird huh!?!?!? I notice it when I'm between (2-3k rpms) or coming from a stop hitting 2-3 gear but not completely sure could be 4th 2-3k rpms on accelerator is a strong vibration....need help guys please!?!?!? Did I fuck up something with me installing my coilsovers!?!?? Or is it my transmission!?!??!? Idk I need feedback pleaseee!

Btw coilovers and spring feel fine smooth ride of bumps not clacks or rattle little rougher of ride now that lower ofcourse but I can't imagination. Accelerator vibration has to do with them! Help pleaseee thank you!!!!!

 

Lower the TL and you'll find vibration from the half shafts.

 

if it was shafts it be consistent vibration from uneven or rough roads right? Why would my accelerating cause vibrations with the shafts...I have yet to get my alignment cause I droppped it two days ago so maybe that'll help with the strong vibration
