Tranny problems
I have a 99 civic hatch standard d16y7 1.6L. My tranny literally blew up on me. My first car, loved it, drove the hell out of it. For about a month before there was a grinding in the tranny. It wasn't the axles and a tech I work with that been in the trade 20 years said it def was not the clutch. He couldn't describe it other than that when the clutch disengaged the noise stopped. He's a racer too, he built a car that runs 5.6's at a 1/4 mile. I trust him. I didn't have the time or money to start ripping apart the tranny. I can't afford to put a new one in right now but it's bugging the hell out of me what it was. And let alone not knowing anybody with the same problem. The grinding was for about a month and then on the way to work going 100 km/h (60 mph) she just blew up.when I stopped there was tranny fluid all over the ground. Anybody else have an issue like this?

Re: Tranny problems
Grinding is a main shaft bearing in the tranny, most likely the input shaft bearing. I don't know why that would cause you to blow your fluid though.

Re: Tranny problems
That def gets me closer to the answer. Still not sure why she blew up on me tho. Only way to tell would be to start ripping the tranny apart which I don't really want to do.

That is not the drain hole, that looks like the snap ring access port to separate the case. And is where the back side counter shaft bearings resides. I can see the snap ring/c-clip in the photo and the bearing it clips to. I also see there are no ball bearings in that race on the counter shaft, so the shaft at 60 mph started slamming all over that part of the case inside the race.
It blows up because the bearings seize up and throws a ball bearing or two and the cage around in the tranny. Then the shaft no longer rotates in a confined spin, instead now it can slam itself around in wide circles putting all kinds of stresses on the gears and synchros and the remaining bearings and the case.
Usually when bearings blow, the tranny isn't worth salvaging. It's typically more cost effective to get a remanufactured tranny and drop it in. For this you will need a case half, who knows what other damage is done to the internals and of course several bearings.
The grinding you were hearing was the clue that your bearings in the tranny were very bad and desperately needing changing. Now you see why you don't ignore grinding in a tranny. The end result is catastrophic.
