About a month ago I started noticing a slight hesitation between 1st and second gears in my 06 Maxima that got worse as the month went on. I changed my transmission mount and that seemed to do the trick but then after a few days it came back only this time as more of a kick than just a slight hesitation. My check engine light lit up and there code was the one for the cam shaft sensors so I replaced them both. That worked for about 2 weeks. Yesterday the kick returned. I checked under the hood to find oil everywhere. It looks like it's coming from my valve covers both front and rear. Also when I slid underneath my car I was shocked to find transmission fluid sprayed everywhere. So now my oil dipstick reads no oil and my transmission dipstick still reads full but I think when I start my car that it will go down. . Can anyone tell me where I should start? I have to work on it myself. I can't afford a mechanic
