Help ! Can I remove the trans, but not the converter ?

The SEALS are NOT what you are worried about!!!!!!! It's damage to the front pump and the mating part of the converter, but mostly the front pump components.

I do NOT understand what the problem is

You remove the starter and dust cover

You remove 4 whole converter bolts, and use whatever means to tie/ safety the converter from falling out.

Remove bell bolts and the damn thing comes right off and the BONUS is, no fluid leakage.
