Transmission fluid topping off using the Level check valve

+1. That's the same type of pump that I used. The clip at the end of the hose is great! I think I got mine from Advance Auto for $5.99. http://shop.advanceautoparts.com/p/...nt-pump-w1141/7070683-P?searchTerm=fluid+pump

 

Yup. Had a flush late last year and got it all back to normal. I was about a quart low. That's what happens when you go 200k miles without ever checking/changing it.

 

My '03 is almost there, had the trans flushed at 150,000 miles. No idea whether it was low or not but it does have a dip stick and last I checked it was good. Which is why I say 1/2 quart shouldn't matter. There is an inch or so which is a safe zone. Not sure how much volume that is but I'm guessing it's somewhere between half and a full quart.
