On mine, I just took the engine out. This is the only way that I have done it, but now that I look back on it, it would have probably been easier to take both the engine and transmission out together. What really got me were the bolts holding the flywheel to the torque converter. Its not so much getting those bolts out, its getting them back in. Takes a lot of time, not very hard though. If you have any real specific questions, I would probably know them. Also, I didnt use a 'engine leveler' which is definatly a good idea.
