It won't even start now, cranks like batts are low. My first thought was TC or tranny, after I shut it down to try the restart, seems like it might be ALT. Guess it could still be TC though, correct.
It's not a flywheel for an auto, it's a flexplate oke:
I broke mine too, this is a great time to do a torque converter and just see how long that tranny will last Andy.
A weight fell off mine and I had it rewelded and balanced at my machine shop.
Not sure on a new one, probably the dealer but order item and spendy if I had to guess.
Biggest question to ask is WHY the flexplate broke, hopefully the trans or TC didn't seize.
