More problems

I was on my way to the multiple forum meet in Issaqua. on the way there I heard some noise from the tanny but it wasnt loud. as I got there the sound had gotten louder. I stayed untill about 9 and decided it was time to make the long drive home. once i turnd on the car again the noise was so loud I was affraid that we would not make it home. Luckly we made the fifty unsure miles and got it home. now I am again without my car. I am now going to have to have my tansmittion replaced already. I have had the 5 speed conversion for only 6 months and it is all needing to be replaced already. First it was the clutch and now the tranny what else can go wrong
