Was helping a newbie change his all his fluids today and when I went to drain the tranny fluid I realized both the drain and fill plugs took an Allen wrench type tool to remove. Anybody know what size it is? Any help would be great. Thanks

 

Mine are not allen, IIRC the fill is a 17mm or 18mm and the drain was a 28mm.... I think. Def. no allen bolts though.


Reading ownz me....did not realize it was for a 9 till now, I have an 8 and the 6 speed maybe different. Sorry.

mine didnt have allen bolts either but i have a 5spd
looks like your fill plug is allen tho

 

10mm hex is used on the Evo X rear diff, the 8/9 MR tranny looks about the same size from what I can remember.

 

Thanks to all of you. Kracka it does look to be about a 10mm hex. I was shocked to see the hex plugs. I'll also check out the link above. Thanks again.

 

That link above is great. Been using the Evomoto site but this is much better and would have prepared me for the 6spd as well. Thanks everyone.

 

Its true, these guys are very helpful..the threads aren't junk like some of the other sites.
I've got to change all my fluids and the link had super good pics!
Thanks!!
