Hyundai Repair: 1996 Hyundai Accent Transmission, hyundai accent, dead transmission

Question
My Hyundai has NEVER had the check engine light come on (except in a few choice situations involving the AC and my water pump). One day I noticed my car was slipping gears, I just carried on with my daily life, had the trans fluid changed. Then one day driving down the road I hear something loud under the hood on the drivers side. It sounded like a loud drill, it responded to the gas, if I let off it would stop, if I pressed it would get louder, until it stops. After parking it my reverse didn't work. So I continued daily driving thinking it can live until I get it to a mechanic. Well 2 days after the reverse went out I was gonna take it out and as soon as it got to 25 (and I assume thats when it switches gears) just proceded to rev up, not responding to the gas, no smoke, no noise, just the engine responding to the gas, with no acceleration. I figured Id turn around take it home and the transmission would catch when I deaccelerate to 25 MPH. Well it wouldn't, so I decided to park it for 5 mins and turn it back on and it did the same thing, 25 MPH stopped responding to gas. Same solution, park, start, repeat until I got home. My friends and I aren't quiet sure what it is, but we know its probably the transmission computer or the transmission itself. Is there anyway to know by this story which it is?


(The check engine light was not on throughout any of this (except a few weeks before I hit a large mud puddle around 55 MPH and it came on for a short moment))

Answer
Sorry, Shaughn.  Loud noises and a car that won't go equal a dead transmission.  Shop around for reman units.  Be sure to include the dealer, Hyundai prices their remanufactured transmissions very competitively.  Given the noise you described, I strongly recommend against trying to repair the transmission you have.  It sounds like a bearing failure and there will be a very large amount of chunks of metal all over the inside of the transmission, meaning many, many internal parts that wouldn't normally need to be replaced will need to be serviced.  Most places which rebuild transmissions will charge extra for these parts, so that's why you'll want to go with an exchange remanufactured unit.
