Oil leak at Rear main seal

An oil leak diagnostic test done at a popular mechanic shop has revealed a leak at the rear main seal.
The mechanic shop recommends replacing the seal, the cost of which is $500.
Is this a DIY activity?
Are there any alternative solutions to this problem like oil additives which stop leaks? If yes how effective are they?

Thanks,
adu

You may have to pull the tranny to get to it, are you capable?

If you figure a seal is $20.00 and the rest is tax and labor, that puts it about 6 hours to do the job for a pro. That's quite a few snicker bars :)

D-I-Y is purely specific to the individual.

Don't use an additive that plugs leaks or you''ll plug more than a leak.

I chk the oil levels even more regularly now.
I am not losing oil significantly.
How long can I live with this problem safely?
What other problems could this lead to?
