My fill and drain plugs took 5mm and 8mm allen's and for the torx screws I used a much smaller allen, don't remember the exact size but if you have a decent allen set you should find one that works.

 

i got home late today and only had time to get as far as getting the filter on. I don't know what size the filter screws ended up being, what I do know is they were the same size as the 1 torx screwdriver I had. I'm gonna finish up tomorrow and fill it up with dexron, and I'll let ya know what happens

 

Just got back from offroad-ing all day with friends. NO problems Did some pretty demanding stuff too and even got a couple of dents
