I've had this DC987 for 7-9 years now. It's pretty much a 18V 1/2" Dewalt XPR drill. I've left this thing out in the rain I've used the bottom as a hammer. It got to the point where the variable speed wasn't working anymore, the torque function was no longer working and one battery that I left in the rain was no longer charging.
I took the drill apart and took the transmission apart. I was surprised to find the transmission gears are made from hardened steel (like an an automotive transmission). I soaked the transmission in degreaser and cleaned it. I carefully inspected each gear and found noting wrong. I re-assembed it and re-packed the transmission with Lithium grease. I bought a new "trigger switch" from eBay for $15 bucks. I bought 1 battery insert and some motor brushes. Now this drill functions like brand new. Most likely sand or some dirt got inside and was messing with the transmission. Much better than paying $200.00 for a new drill.
