Yeah, but lucky you gets to use the common cheap fluid! For her/his car, they are going to need the expensive fluid. A reasonably priced place like autohaus is $15 per liter with free shipping and you should be prepared with 8 bottles. That is $120 plus the filter and gasket kit at $25ish. You are already up to $145 just for parts, not including a new lock clip, required dipstick, infrared thermometer, ramps, etc. The first time you do it yourself on a 722.605, you don't save a whole lot of money but you do have a few items useful for the next time plus other projects (thermometer, dipstick, ramps).
