Customer did not change the oil and the engine seized. I could not get torque converter bolts out because crank will not turn. Engine is out on table. What is the best way to go about removing torque converter bolts now?

Can you just unbolt the transmission bell housing then remove the entire transmission and leave the torque converter bolted to the flywheel, then unbolt it?

No because you cannot unbolt flywheel because bolts are behind torque converter. Wish it was that easy.

The torque converter usually just slides onto the input shaft of the transmission. I was saying don not worry about the torque convector bolts right now, unbolt the bell housing bolts and slide the transmission out of the torque converter, then unbolt the torque converter from the flywheel.

This is what i was told to do by other forums. What do you think. Same type of engine and transmission really, Honda Hyundai all roughly the same. i can unbolt the transmission yes. However, once the transmission is off the engine the torque converter bolts are still on the other side against the engine crank does not spin.

Yeah, that should work, once you get the oil pan off you should be able to either find out why the engine seized and unbolt it, or just start unbolting all of the crankshaft bearing caps and connecting rod bolts, if in fact you can get to them all. You should only have to crank loose the crank bearing bolts but the rod cap bolts you should remove all of them unless of course it is obvious what connection rod broke or which piston seized, etc.
