I was driveing my car home last nite and my check engine pops on....(so I think to myself ill get that fixed tomm....) well I continue driveing and all ofa sudden it sounds like the Trans is poping and clicking.....well I pulled over and called a buddy to tow it to my mechanic....He glanced it over today and said it was def the trans but thats all he knew untill he took a better look at it.....well I was wandering if anyone knew what it could be. A few people thats heard it says it could be the univ joint or a tooth in the tranny has been knocked off. Just curious on what yall think it is.

If I push on the clutch the rattling/poping noise stops. I can also drive the car but it click and pops BAD.

 

If it stops when you push in on the clutch, it may be the input shaft. Start it up and put it in neutral and let out the clutch and see if it does the same thing.

 

soundslike input shaft or even the pilot bearing went bad causing a vibration in the crank.....check the trouble code and determine from there. clutch could've crapped the bed also
