C-4 tranny question
 

When I was putting my 82GT back together last winter I accidently pulled the input shaft all the way out of the tranny.
I've was told that it's important that it goes back in exactly how it came out even though it will go in other ways.
Now that I have it on the road, I notice bad vibrations,especially during de-acceleration. Do you think that since I possiblly installed the shaft wrong that it could be the problem?
I was also thinking of worn u-joints, unbalanced drive shaft or unbalanced wheels/tires.
If I get the gas pedal in the right spot then it seems to level out.
Any suggestions?

Re: C-4 tranny question
 

I have never heard that about the input shaft.:confused: I have taken mine out and put back in various times and had no problems. I would look into the easiest stuff first. The tires and wheels. Then look at the driveshaft and u-joints.

Is your harmonic balancer in good shape???

As long as the splines line up and its seated correctly, it will be fine. My guess would be the driveshaft, unless you had gears installed that were not set up correctly.

Doesn't matter
 

I don't think it matters which way it goes back in. Sounds like u-joints to me. They are faiirly easy to check, just look for slop.

At first I thought it might be u-joints but I don't hear that familiar metal "clank" sound. I'll check it out though.

My '94 ForeRunner did the exact same thing that you described and it was the u-joints. I think you can confirm that diagnosis by getting under the car and checking for slop in the u-joints. If it's the u-joints, you should be able to see it.

Found the problem. The driveshaft bolts were all loose!!
When I put the engine & tranny in the car, I must have only tightened them hand tight and forgot that I did that.
No vibes now!
