Back story: 4L60E, TCI flexplate, Yank 3600.. Lost 3rd and 4th sold the YANK.
Newish 4L60E (got it from a member) TCI flexplate and reman stock converter. When i did the trans install i used the stock converter bolts(allenheaded). And on start up they hit the block BANG bANG bang. Shut it down pulled the bolts and put some lower profile bolts in.
Now under light load (in drive while staging) I can hear what sounds like the converter bolts hitting the block again. I pulled them out no damage to them or their heads. Under full throttle you can hear noise on take off but goes away as the power comes on. I plan to put a spacer between the coverter and flexplate in the morning and see what happens..
ANY IDEAS WOULD HELP thanks LS1tech!!!!
