Why won't my Versa start?

Okay #1. to start with replacing the starter and battery has nothing to do with transmission going out. Now you can't hear the starter making contact with the flywheel did you get the right starter? In the past 2-4 months did you hear anything when starting the car? If you did that was possibly the starter going bad.#2. your driving down the road and all the sudden you have no drive no matter what gear you're in, check the transmission fluid level it should barely touch the botom off the trany dipstick since you can't get the car started to check it the right way, if you do see a little bit of fluid transmission is shot, at the very least the flywheel. Either way transmission is coming out!!!
