I found that the tranny on my truck is leaking or seaping fluid. I can see the 4x4 pan is wet all around the seal and flowing down and dripping from the bolt. I auto cross my truck often and I am wondering if this leak is just over from heat or a more serious problem?

I'm also considering switching to either the moroso or B&M pan due to clearence, I have about 6 inches from the ground to the 4x4 pan bolt, anyone happen to have the part numbers for either of those?

Thanks
