    Just finished my 4" lift, I have a crate 350 and a 465, I noticed since my swap, if I gas it hard, my whole tranny shifter lunges forward, am I dealing with bad tranny mounts, bad motor mounts, both or some driveline related issue such as axle wrap thats binding it enough to make the whole system shift forward

    Proabably a bad tranny mount, motor mount, or both.

    My shifter kind of goes forward when I gas it, and I had new motor mounts in last year. I dont think it's as sever as yours, so I'd check tranny mounts first.

    I guess its time to do both anyway as I don't think the tranny mount has ever been done and the engine mounts have been sometime as well, not to mention my motor is fairly torquey and I have blocks out back /forums/images/graemlins/eek.gif /forums/images/graemlins/ignore.gif

    I'd say from rest to gassed the shifter moves about 6" forward /forums/images/graemlins/ignore.gif /forums/images/graemlins/thinking.gif

    You'll really like the loss of driveline slop when you put in the new tranny mount. /forums/images/graemlins/smile.gif /forums/images/graemlins/thumb.gif

    Come'on you think a 250+lb tranny on a 20 year old peice of rubber does bad things? /forums/images/graemlins/rotfl.gif
