C4 input shaft strength ?'s
Hi all, some of you will know me from my C4 buildup info that I have posted here before, now I have a questions for you all.
What does it take to break the input shaft as I just had a guy that I built a C4 for break one and I am very surprised as I have never personally experienced this failure before. Is it really possible to break one with just a stock 5.0 HO EFI or could there be something else going on here that I have not seen yet? The trans is fresh has 5 clutches in each pack and has a forward pattern full manual valve body in it he chose to use a stock converter so it shifted very hard, but otherwise worked great, any thoughts on how to get the broken off piece out of the converter as it snapped off right there in the splines that go into the converter? I will be doing a thorough take down of the trans to check for any other damage and will let you know if I find anything unusual. Thanks All
