with this problem you can definately feel the car shifting gears when driving but most pain in the ass is on the gear shift if the rubber boot on the switch to to shift the gears is not in the right place then it locks the key in the ignition also so you have to keep messing with it until it releases your key .... That part I figured out yesterday but going to hv to hire someone who works on transmission for this problem heard is just a chip I hope so I dont think I can handle anymore repairs in one day and we thougth we were getting a deal Jokes on us!!!!! But what can I do my last baby girl loves the car just hope thats the end of it.
