4R70W Transmission question

4R70W output shaft bushing removal/install

I have a 99 GT automatic (4R70W) 103k+miles on it. It has a leak coming from the tranmission output shaft. I bought the seal and bushing kit. I figure since I'm there changing out the seal, I might as well change the bushing out also. My question is, how do you get the bushing out and the new one in?
If it's a real pain in the arse, then I'll just change the seal and call it a day

Any help/input is very much appreciated....

Yep, it's certainly more work than I want to get involved in...there is a specialty tool to remove and install that bushing that I found on the net...but it's over 100 dollars...So I think I'm just going to change out the seal. Hopefully that takes care to the leak.....Thanks a bunch
