Re: So, how badly did I wreck my transmission?
I would put a new flexplate while it is out. Absolutely I would put a new front seal.

For the price of a flexplate, I'd put a new one on.

Re: So, how badly did I wreck my transmission?
Thanks, guys. I will definitely take your advice when it's going back together.
My first car was a '71 VW bus I rebuilt myself in high school, but this truck is a whole different animal (and I had "The Compleat Idiot" book by Muir to help me back then). You can't exactly drop a 350 onto a skateboard and wheel it into the garage like you could with the 1600cc VW engine... probably also explains why I called it a flywheel and not a flexplate. Learning is fun, I'm glad this resource is here. Quote:
One day I crawled under the truck to check something unrelated, grabbed the flywheel (sorry, flexplate) for some leverage, and noticed that it wiggled. Like, a lot, back and forth. I torqued down the bolts, and the noise was gone forever. The truck was clearly put together just well enough to sell at auction, which is the main reason behind the current rebuild. Fun stuff, thanks again. |

Re: So, how badly did I wreck my transmission?
well then the bolt holes are probably beaten out of round and the flexplate should be replaced anyway

Got it home and looked under the truck. There was dent in the shape of a bolt head in the bell housing cover plate. Removed the trans and found one of the pressure plates bolts was missing... then I found it jammed into my clutch. It somehow got loose, shot into the cover, bounced back, got into the pressure plate somehow and jammed between the clutch and the flywheel.

Re: So, how badly did I wreck my transmission?
Whatever you do, DO NOT spin the flex plate on your finger to see if it is bent or not. I did it back in '83 when I was putting a trans in my wife's first car (17 yo GF at the time), a 68 Chevelle, and it about cut my damn finger off.
