im changing the tranny and diff fluid on my AP1, and i was wondering if anyone could help me out and tell me what the sizes for the drain and fill bolt heads. With my work schedule, I hate to get under the car and find out i don't have the right size wrenches. Thanks

 

it's in the FAQ

 

dif drain 24mm or 15/16
dif fill 23mm

trans drain 3/8 ratchet with no socket
trans fill 17mm

engine drain 17mm

 

also 15/16 for the diff will work, thats what i use
