Is it missing the top two bolts? Im pretty sure they're missing but I've never seen this trans down before so I'm not sure of the bolt locations.
I've noticed a rattle under load only and at 2k rpm and up. Had the transmission down for a torque converter install about 12 months before I noticed the noise. Would/could the missing bolts cause the trans to rattle against the block?
