Ok so today on my way home after showing my stang off to some coworkers ( i work at a phosphate mine so i never drive it to work cept today ). I was headed down a long stretch of highway and laid in to it. the tach just slammed into the rev limiter and i got out of it. the car down shifted after i got out of it and eased back in. 5 or so miles later tje car started to get a shuttle like a shake. leaving the next light i got into it again and she jerked and free revved. No more 3 and 4 then no more 2 then it just stopped.moving altogether. im wondering if i lost the torque converter or the transmission.
