Eliott Posted May 14, 2020 Share Posted May 14, 2020 I have a 2003 Mack CH613, I was trying to check my transmission fluid, I was told that on a 13 speed, I would find it on the driver's side about half way up. They told me it would be a 3/8 male or female plug. I found something different, not sure if this is the plug or not, I went to make Mack and got a diagram, and it matches the placement but looks different. I will upload the pictures below, if any one could help me out, I will appreciate it. Quote Link to comment Share on other sites More sharing options...

br549 Posted May 14, 2020 Share Posted May 14, 2020 That's the right place, somebody welded a wheel lug on it. Quote Link to comment Share on other sites More sharing options...
