I recently broke mine and I searched all over this damn forum for info about shifter linkage parts, so I figure I'd contribute a little bit of info to help out anyone looking for a solution....The connecting rod is what busted on mine, it's a PITA fix but it can be done if you're going to do it yourself. In order to replace it you need to take off your drive shaft to get to it. But for those of you who need a part # here ya go. my car is an 06'

Hope this can help you guys. The part from Nissan is around $115 bucks. If you go to a shop to get it fix it'll set you back around $500 bucks. They wanted to charge me over $209 for the part! Labor to fix it is about 2 hrs.

The repair can be easier if you have a lift.
