Hi,
If you are only removing the sleeve, the transmission doesn't need to be taken apart. If it is already loose, you should be able (once the cv axle is removed) to remove the snap ring and remove it. However, you will need to replace it. The directions indicate not to reuse it.
If I had to guess, I suspect that is because it would get damaged by the puller, but you won't need to do that since it's already loose. Also, I have a feeling the snap ring was lost at some point which led to the sleeve coming loose.
I hope this helps. Let me know if you have questions.
Take care,
Joe
