Default 1995 transmission to block bolt size ? Automatic

Can someone point me to the correct bolts for a 1995 auto, to bolt the trans to the block. I’m getting metric and SAE bolts in my Google searching

3/8-16 is correct and there's generally 1 that's a stud. I've seen 1 3/8 length mentioned a few times, but you should easily be able to determine a length by just measuring case and depth of threads in block. Flange head preferred maybe.
