You do have the proper amount of fluid in it, correct? You checked it? I'd imagine someone would have a baffled pan or pickup extension to aid in it. Last auto rig we had in the bunch that slipped was a quart and a half low on atf.

 

I need to check the fluid but is should be full since I changed out my filter etc about three weeks ago. I've been looking for a baffle but I guess not hard enough lol

 

Yeah check the oil level in it. I've had mine up some very steep stuff and have not had this issue. Good luck!

 

Never had that issue, but I put all of my fluids to the full mark before wheeling every time.

 

rock krawler is making a new pan thats deeper sump and also acts as a skid
