You have to drop the transmission?

I've only done this job 4 or 5 times, so not a lot of experience. I was never able to remove the old upper seal and pull the new one thru properly without slightly dropping the crankshaft, and I wasn't able to do that with the transmission in place. I don't recall how much I lowered the crankshaft, perhaps 1/16" or so but it's important to leave the crankshaft supported by all the mains so you need to lower evenly. Perhaps others have different experiences.
