I 've got a 85 monte with a 305 and 200r transmission that i swapped for the v6 and in the donar car it was working fine but now the kickdown cable doesn't spring back and was told by a buddy that the spring may be borke or just need a whole new cable .I have never done any type fo transmission work befor and was woundering if anybody has ever done this bofre or if i sould spend so more omey and take it to a pro. 😀
