hard shift
Around 30 mph it hard shifts no matter what load it's under. Whether I'm accelerating or braking. The fluids are good and I recently put in lucas oil auto tranny fluid conditioner. Any ideas? Also when park the car rocks back and forth

Re: hard shift
Check the common issues thread at the top of this section of the forum. Under Transmission - the top 2 issues are the likely suspects. The first one, being the front transmission mount is more likely, from your description.

Re: hard shift
Sounds like a misfire. How old are the plugs and wires? Are you running premium fuel?

Re: hard shift
the coils and the wires look almost new, but they may have cleaned them. i plan to replace them but of course no $. and ive ran premium fuel with no ethanol ever since i bought it.could it possibly be the torque converter?

Re: hard shift
That chugging is most definitely ignition system related. Check the plug on 3, then the wire and finally the coil.

Re: hard shift
Update: it was the coils. Changed the plugs. And most of them were shot.. I had no central electrodes left
