Water in floor after trans work

Is there a seal around the shifter floor plate or did the shop I just have do work screw up like every other shop I’ve had work done at? I had work done at a Cat shop, rebuilt trans and new clutch, and they didn’t even adjust the clutch after the work sadly. Seems like every shop I go to doesn’t do what it takes to get the job done. I snaked the drain tube for the a/c (and it actually makes the a/c work better thankfully) and things dried out but after another rain the floor got wet again. Pretty sure it’s coming through the shifter hole and I don’t want to take it apart out on the road and make it worse since it’s the weekend and places are not open where I’m at in case something breaks or or something is broken already. I’ve googled for a seal and nothing came up so here I am asking.

 

The boot has a small hole but there is no water on the plate. There has to be some sort of seal under the plate otherwise this would happen. Have you seen the underside of that plate? Is it integrated? I ask as there is water behind the shifter.
