You're welcome.
My trans doesn't jerk from 1st to 2nd all that badly, unless I'm accellerating really quickly, which is most of the time ::haha:: Maybe I'm used to the car by now, but I don't ever remember doing anything more than thinking to myself, "There's that 1st to 2nd shift jump I've heard about."
Mine has never been so bad that it bothered me and I'm usually picky about stuff like that. If it ever got worse, I'd check into it.
So far, my trans is original. I checked through all the service records and don't see anything stating the mounts have been replaced, so those should be original, too.
It's hard to tell without being in the car what another person considers "too abrupt" a shift. I think the important thing is that you found it bothersome enough to post a thread, it's your car and like BK you should have it "your way," so you should definitely consider all the options available to reducing it as much as possible.
