someone sabotaged 2004 buick rendezvous v6 3.4l fwd by pouring in motor oil in transmission fill tube and overfilled it to boot. I know I need to pull pan and filter and drain it but that won't get it all out. what's my best options? this car can not be replaced nor can the transmission or torque converter for financial reasons, I have to get this problem taken care of myself.

Hopefully you haven't driven it and you can tow it to the shop. The pan needs to be dropped and then the system hooked up to a complete replacement machine to flush it with clean oil.

You may have already done damage. The sooner you get it flushed, the better.
