  • Transmission clunk??? 4L60E

    Ok, first... Had clunk while accelerating between gears. Replaced transmission mount, fixed that problem... Then after I replaced that, on my test drive, I accelerated and before it hit 1st gear it felt like it jammed into gear, just slightly, not as smooth as im used to... once in gear I can full throttle and everything runs smooth. Its an auto with 68000 miles. 4L60E

    You sure you're not just feeling the shifts now that the transmission is actually mounted in place?

      If you used a poly trans mount, they are real stiff at first but break in after a while.

        if the jamming into gear gets worse and the check engine light comes on, it could eventually be a valve body issue. I know I had that problem with my old bird. Otherwise, like they said, you could just be feeling more because poly trans mounts make you feel EVERYTHING.

              it feels like when gear engages from stop to acceleration...it shifts into gear hard, then smooth transitions all other gears...
