Ditto. I didn't know that the first time I pulled my slant six. I ended up stripping a lower bolt hole when trying to mate the rebuilt engine to the tranny. You must spin the torque converter several times and keep pushing until the bolt pads sits at least 1/2" back from the face of the tranny. It requires that 2 shafts engage, or such. Yours may slide out a bit when you pull the engine, so always check. Getting the 4 torque converter bolts loose sometimes requires a special wrench. I usually use a set of offset box wrenches. And paint one of the bolts on both sides since it bolts up only one way. You can usually use a screwdriver on the ring gear to hold the transmission from turning.
