Cracked flexplate :(
Cracked flexplate :( I got a call this morning from the trans shop that is installing my trans and stall saying my flexplate is cracked. 
I was planning on taking it to the track this weekend but am not going to be able to, I'm waiting for them to call back then will probably have to overnight a TCI, its an extra $250 that I didnt want to spend

im sorry to hear that man but from what i can tell it happens regularly. seems the 98 and 99s have a heavyer but stronger stock flexplate than the 00 through 02. not a bad upgrade though if you think about the damage they can do when they come apart.
