hand knowledge. If plumbed it independently, but you place the trans oil rad in front of the evap, then you will increase the heat load on your a/c (a very bad idea). Best way to free the motor and a/c of the trans' additional heat load would be to plumb ind but place the oil rad, with its own fan somewhere its heat does not reach the evap or water rad. Don't know where that would be.
Take for instance FMIC. All the heat they dissipate goes into the evap and rad. To remedy this, some place the water rad flat (parallel to the ground) with its own fan. Don't think I have seen that set up with a/c.
