It's my understanding that on a E40D things are little bit weaker than the 4R100 and I wouldn't generally use either to try and hold back a 15K trailer, but for small loads (2K-4K) it should be fine. The Coast Clutch is the smallest clutch pack in the transmission and can't handle too much abuse, at least how I understand it.
