Hello , guys

I just started a job of removing my Honda civic coupe 2003 1.7 vtec petrol auto gearbox removal.
Because torque converter has gone, I want to take it off and send it off to be checked.
I have came to a point where I have stripped everything that was necessary to remove it.
I have unbolted 5 bolts which are holding the gearbox and have unscrewed 8 bolts which are for flywheel.
All mount has been removed and nothing is holding the gearbox. But gearbox hasn't even moved a little bit since I unbolted it. Torque converter is spinning freely from the engine. So the is it possible that it is just seized together so hard with the engine , that even transmissions weight is not enought so it would come off ?
Tomorrow will go outside try to check all the bolts again , but I am pretty sure that there are no more bolts that is holding it.

Has anyone had any experience with this job on this cars ?

Would really appreciate some advice .

Thanks , Tom
