Vibration/Rattle sound inside car after transmission change?
Finished changing my transmission this morning in my 2004 Trailblazer 4wd. Seems to be running good, no problems shifting or anything, but ever since i took it off the rack there is a big vibration sound. Sounds like its right under the shifter. At first it seemed like it was only when i was in reverse, after driving for a while it does it in drive also. Doesnt seem like a transmission problem, but funny how it never happened until changing it. Any input would be appreciated.
