I noticed a small leak coming from my tranny the other day so I took a trip to the dealer since truck is still under warranty. So they checked it out and what they came up with was that the lift was causing the leak since it changed the angle of the driveshaft as it goes into the tranny they said it ended up wearing the seal and the housing. So I asked if this happens to all lifted trucks and he said some but not all. Seems strange to me but has anyone expirienced this before with your lift. At the end he said it might just be a bad part which I'm hoping for. Thanks guys

 

I had that problem once on a lowered truck. It was just the seal, replaced it no more issues. Good luck.
