i got similar problem but bit different
for me it feels shaking and noticable int steering wheel going left/right abit

more speed more shaking...

changed wheels around and its second set of wheels im running
so i think they all wont be out of ballance..

any ideas?



man if it is ok on neutral then it would be weird as abs work on neutral as well (?) and u dont change anything in rotors or calipers or anything in breaking system... so logically it s transmition...

tried to pull tranny codes for excisting and previous problems?
