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

 

what kind did you have that cracked? TCI? i saw that speed inc makes one, im in the market for one but i definitely dont ever want one to crack on me.

 

no a stock 01 with over 127k miles, Im going to probably order the tci

EDIT: Just saw the speed inc one and am about to give them a call

 

let me know what you find out, i wonder what the differances are? quality as well?

CATFP346 LS1/LS2 F-body/GTO, Truck SFI Approved Flexplate $119.99 buy I figure the speed inc will be plenty strong for my combo, heads/cam n2o 346" so I already ordered it and had them overnight it, Ill post pics when I get it

 

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.

 

Mine cracked as well...Went with a TCI (sfi).

 

I had that happen to me too and got the TCI flexplate. Its worth it.

 

my stock 02 one cracked too with less than 70k i bought the one from speed inc its made by cat and its sfi 29.1, its really a nice peice and the starter ring is alot thicker then the stocker which is where mine cracked in several spots

 

if i had the cash i would have went with the TCI tho...
