Hey everybody...I have a '94 Subaru SVX LSi. Its a pretty good car...got it cheap. 3700 with not too high of miles on it. Its the typical pearl white with black top. Its pretty quick too. I dont really know what it is, but if you kinda...press the gas twice..its like some sort of mini boost, skips a gear or something, hell if I know.Umm..I took it out "rallying" one night on some dirt roads. Super fun..BUT...ruined it. When I bought it, there were Konig 16s on it...damn near brand new Dunlop(did I spell this right?) tires. I balded those down real nice. Eventually had to get all brand new tires and rims. Now I have Enkei 17s. I kinda wish I got the 18s now but oh well. So yea...ever since I did that, I think I screwed my tranny. Its not as fast as it used to be. =( I know Im a ********************* but...does anybody know anything I can do to 'fix' it? I really dont want to resort to buying a different car...cuz as you know...trannys are NOT cheap. Any tips or tricks would be much appreciated. thanx
