I dropped my transmission on the floor?

My transmission was inside. I picked it up to bring outside and fell from my hands on the tile floor in my house. It fell maybe a foot and a half high. Not high. And fell on to tile. I wanna know if I should have any problems. I didn't hear anything break or see any cracks. How durable are transmissions. 99 Honda Civic si

99 Honda Civic issue?

My neighbor has a 99 Honda Civic with 250k he parked it this time last year when he got his new car. He told me he would sell it to me for $50 since it's older and needs a tie rod. Well today we went to start it and when it starts it squeals very loud by where the serpentine belt is. And he said if you don't keep giving it gas it dies. I kind of sounds like one of the pullys are stuck. He said it ran and drives great when you parked it. Any ideas?

94 HONDA CIVIC NOT STARTING?

I bought this vehicle 2 days ago. The person I bought it from said only thing wrong with it was fan… I drove car first day n it seemed to run great. Started to over heat once but it was very minor. Yesterday I drove car to drive thru for lunch n when I tried to start it again it refused to start. After a while it started n I went back to work within a few blocks down street. After work it refused to start again. I hit the started a lil bit and It turned on. So I guess it needs a new starter now too? On the way home i pulled over to side of fwy to check under hood because the fan doesn't work. This time when i tried to turn it back on it doesn't even attempt To crank or make a clicking sound. When I turned key all the lights turn on like normal as it has a new battery but instead of the typical crank you hear it was silent with only 6 beeps before it went silent again n when turning key to try again it made one loud alarm type beep. It's been a few hours and there's no change. I got a jump start from a tow truck just in case but that wasn't the problem. Tried to put car in neutral. Shook car. And it remains the same. 6 beeps with no signs of it trying to turn on n 1 loud alarm like beep. Car didn't come with alarm control so I don't thinkit had one if that makes a difference. Not sure what else to try? Any suggestions?

What is this loud noise when I shift into D?

This only happens in the morning… When I shift into "D" there's a loud noise like loud chattering coming from under the hood. Only happens in "D" and only in morning. Never happens rest of day.
