2000 Other Saturn Models Rear Main Seal

Engine Mechanical problem
2000 Other Saturn Models 4 cyl Automatic 135000 miles

I had hoped to replace the rear main seal by removing the transaxle but it looks like the transaxle will not come down past the subframe. There are also a few bracket bolts that would be near impossible to get to. Can the transaxle be removed by itself or must the engine and trans be removed as a unit? Thanks for your help! I need it! By the way, I have an LS model with a 2.2 liter engine. Thanks again
