i just bought a 88 mustang GT 5 speed. with the current setup its running about 410hp. the last owner said it keeps tearing up the T-5 transmissions. what would be the best performance transmission upgrade for a stang running that much HP? its going to be a daily driver and i dont wanna waste money on a transmission my car is going to eat up.
