If the coupler is snug in the pocket check your engine with a coupler gauge. It may be you need to change to either a inderst or overset coupler

Check on the pin in the coupler box to make sure its a snug fit to the hole on the coupler the wrong size coupler shank hole could be causing all your trouble I have had to change coupler boxes before.

In most commercial locos and rolling stock you can generally assume that the front, bottom lip of the box is the right height, but that the shank may sag due to the weight of the gladhand, a thin shim at the top rear would have the effect of lifting the front. As Dale says, the shim might cause binding so be prepared to pare away unwanted thickness.

There are two good and one “bad” fix for loose or drooping couplers. The “bad” one is to put a thin shim in the coupler housing. The problem here is that it may make it too tight or bind with the shank and limit the free swinging of the coupler. A better way is to carefully file away a bit of the rim of the coupler housing, effectively making it shallower. Just don’t overdo it. The third way is to replace the couplers with ones having a slightly thicker shank. Measure the ones you have and research the couplers on the manufacturer’s web site. Most have engineering documents posted that show shank measurements.
