I am in the process of dropping the automatic transmission on my 1969 GTO Convertible restoration project. I have disconnected the shift linkage, the cooling lines, and electrical. I removed the cross-member and the three bolts that hold the torque converter to the flex plate. The torque converter turns easily by hand. Last night I supported the trans with jacks and removed the 6 transmission bolts. I raised and lowered the transmission with the jack to try to break the transmission loose from the engine block but it seems to be stuck. I went back over each step to make sure I disconnected and removed all bolts and anything else that may be keeping it from breaking loose. I also put PB Blaster on the aluminum pilot tabs to make sure they are loose. Did I miss something or is there a trick to getting the transmission to break loose from the block?
