I have a question for my car. I have a 1985 Buick Grand National Clone which i got on a super deal, I traded a set of 20's for it but it needed a motor. The body and interior is ok. Well, it had a shot 3.8 V-6, so we went and put in a 307 V-8 out of a cutlass. My question is, before the old motor went, the guy i got it from said the tranny was ok, but when we finally got the motor in and fired up, the tranny just stays in first for about 12 seconds, then the joker rockets into second and jerks the hell out of you. We couldnt figure it out, until i looked and noticed the kickdown cable was hooked up but isnt working at all. I mean its totally broken. The tranny is the 200 series. Could it be just the broken kickdown cable or is it the worst...fried tranny?
