I bought a 99 trans am last weekend with a bad transmission. I got a trans today out of a wrecked trans am with 20k. I then realized that the transmission has this torque converter in it. A TCI super street fighter 242932. I was going to TRY and keep this one stock besides the headers and exhaust it already has and keep my 2000 trans am for racing. BUT what the hell... I am gonna leave this converter in for now. I want to put this transmission in the car tomorrow after work so I can actually drive this thing. MY question is.... what torque converter bolts do I use? Can I use the stock ones? I work at a Chevy dealership and we have new stock replacements in stock. OR do I need special fancy pants TCI bolts? Do I have to drill out the flex plate at all? AND where can I get these bolts? again I want to do this tomorrow nite.

The early ones used the stock metric bolts, later ones use 7/16" fine x 1" or 3/4" length.

crap.... can I just get some grade 8 bolts from hardware store or do I need to order new ones from tci?

hardware store grade 8s are fine and you will need to drill one hole on the flex plate

Ok your right, I just went and got a regular 7/16 fine thread bolt from the parts room and it threaded in smoothly. They arnt grade 8s tho. SO I will get some new grade 8 7/16 fine threads 3/4 in long and go from there.. THANKS FOR THE HELP!
