Wanting to change the fluid in my NSG 370 6 speed 2005 TJR and I cannot find out what size wrench for the drain plug and the fill plug. Pretty obvious they are two different sizes and probably metric. Anyone know what I need to acquire to get this job done? Thanks.
 
Okay. A little more research indicates the drain plug is 17 mm hex and the fill plug is 14mm hex. Sound about right to those that have done this?
 
Correct, 17 and 14 mm. I picked mine up at Harbor Freight. They come in a full set but are less then 20 bucks.
