I was changing out the axles (bad cv boots) in my 2007 Lexus ES350 and pulling the axle out of the transmission, it leaked about a quarter to half quart of transmission fluid out. The transmission slips a little in the first 1/4 mile of a drive (historically). Before I put the new axles on is there anything else I should do? I am thinking that there is a bad seal in the the transmission (not sure). I am not sure what I should do or where I go from here. Any wisdom, suggestions would be appreciated.

Put everything back and check the fluid level, probably you should add some.

Is there a way to put it back in myself (lifetime transmission fluid/no dip stick) or will I need to take it into a shop?

If you have the Techstream you can do it yourself.

Prior to a friend changing both front axles for me he warned me that it was a possibility that some atf might leak out. He had me pick up a couple of quarts just in case but never actually needed them.

Here is how to add more ATF, but checking the fluid level is very difficult. If you feel sure of the leaked amount, add 1/4 quart and see how it drives. If it still slips, add another 1/4 quart.

This is how I do it on the RX when I do my annual drain and fill of about 2 quarts. I suspect the ES is about the same as it has the same transmission.

Remove driver side front tire.
On the forward lower part of fender liner is a small plastic trim piece you must remove to get access to the transmission fill bolt.
I recall it is held on with some plastic clips and maybe a screw, pry it off.
Under it is the fill bolt, it is rather large, like 24 mm or similar. You will need a long funnel, easily available at any autoparts store or Wal-mart.
Measure the exact amount of fluid into another smaller container before pouring it in as precise measurement of the amount is the key to success!
Test drive and see if all is okay.

When I replaced passenger side CV axle shaft, I had passenger side up about two inches higher than driver-side and didn't lose any ATF fluid. Not a bad idea to replace the AT housing tranny seals where the axles go into the tranny; this ensures no leaks, if installed properly. Got mine at Napa; only about $12 each.
