Hi guys! So I got my newly built 4L80e and 461 broken in and running and everything has been great except I have a large leak coming from the trans above the pan. We pulled the trans back out and had it check by a good trans specialty shop and he said everything was good with the seals and the pumps. In his opinion the bolts around the adapter plater are coming loose because they support the entire weight of the trans instead of the stock intended bellhousing. Not sure if that makes sense to me but I thought I would see if anyone else had any experience with this or could point me in the right direction.
