98 taurus.....motor mounts???

I have a 98 taurus w/ 3.0l 24v dohc.....when i first put it into gear it jerks forward really hard....and when it gets warmed up it feels like it will slip out of gear when i turn and slam back into gear when i hit the gas again, and taking off from a dead stop it feels like it slams into gear....thought maybe this was a motor mount issue....car has 132,000 miles on it....PLEASE HELP

open the hood with the engine on and trans in neutral and have someone floor the engine, if the engine violently rocks back and forth, then its a mount, if not, then its a transmission problem that is probably best solved with a rebuild/replace.

the problem turned out to be nothing transmission related, the front upper & lower cradle mounts were shot, installed new ones...problem solved
