Ok...I have been tinkering with my exhaust lately and when i started it up and crawled underneath to listen for exhaust leaks i all i could really here was a loud clicking sound coming from the automatic transmission area.

Last night i was crusing down the highway and there was a weird vibration coming from under the seats as well. Then it would go away.

I thought it was my exhaust but now im thinking it possibly might be the transmission.

Any ideas?

 

mine is starting that too, dont know what it is though. May be the driveshaft vibrating. Something may be loose making a ticking sound.
