size of bolt - torque converter to flexplate

Hello everyone it's been awhile since I have tried to tackle my problem due to a bad back and the feeling that I might never get it done ...but my enthusiasm had returned and I need to know if anyone knows off hand the size of the bolt on the flywheel to release the torque converter from the trans.on my 97 Deville .if u follow the post I sent I'm still stuck with trying to separate the block and trans.I see that I can just barely separate the two just enough to stick maybe I hope an open end wrench in between to release the 3 bolts just née to k ow the size or any helpful info ....thanks to all and keep ur caddy shining

:yeah: There are four bolts, and if you're lucky, one might be accessible through the starter hole. Might need an offset wrench though.

The bolts are already destroyed. You could use whatever method now to remove the bolts, and then buy new bolts. Vise grips maybe?

You strip them all the way? I have had issues with 12pt sockets slipping on the edges of the bolt. Find yourself a nice 6 point socket or wrench and it should help you out.

Also, you are talking about the flywheel to TC bolts, right? I think there are 4. I used a 18 wrench or whatever size it is and ground off one side of the wrench to make it slip through the access hole on the bottom of the engine. It worked out real slick.
