Not really describing answer , but i would assume you shifter cables have broken
Loose hold down clamp or broken shift cable.
Sounds like the linkage is loose
If you follow the shifter down to the bottom of your Durango, you will see that the "C" clip that holds that shifter to a transition bar that goes back to the gear case has fallen off. The bar should still be dangling there and you can replace the clip. (hopefully) Gene
to install a clutch in a dodge stealth, looks hard but its not. you have to drop the axles out. to do this you take lower ball joints, loose at lower a frame then take the axle nut off at the axle. it will be easier to loosen the sway bar then you can take out the axles. then from there you take the bolts loose from the trans where it bolts to the motor. there are other items you have to remove but its been awhile since I have done one. there is one electrical part that you don't want to get pinched when you go back with the trans.

It may just be a screw came loose underneath your gear shifter. That is what happened to me. Just slide the stuff up to the top of your gear shifter and look underneath. If one of the bolts is udone, just simple put it back on.
Loose or corroded battery cable? Loose cable at starter? Bad starter? Bad starter solenoid? Bad or misadjusted clutch safety switch?
I have this same problem. A broken shifter box. I will repost a fix as soon asap.
Most common reasons a vehicle will vibrate: "bubble" on a tire; front wheel alignment; loose u-joint; bent or damaged drive shaft.
If loose they will need replaced.
