4spd acting up, need advice
The last couple days I noticed I couldnt down shift into 2nd at all, even at stop sign. But if I go through the gears 1st to 4th it seems ok.
So I got under the car checked linkage at nuetral position and both levers perfectly straight up with no loose connections or anything obvious. Now today at a stop light, I put it in 1st but the car wouldnt move until I fiddled enough with it and finally got to work. I dont think I'm going to make it home tonight.
So.... my question is, would the tranny gears or synchros be able to cause this type of situation? I had the tranny rebuilt 12,000 miles ago.
Or does this sound like linkage only problem? THX

Not sure about the 4 speeds,but years ago had shifting issues with a 57 chevy PU (three on the tree) and it was the bushings in the linkage...
Edit:Assume you put new clutch in,so checking pedal free play is a good idea also....

ditto on the bushings and Hurst. There are some good websites for 4 speed info. You might try Autogear.com or Auto Gear Equipment Company that specializes in Muncies....has good parts and price list (XPENSIVVVE!) to download/review. Also, have developed some better ideas for old problems such as a stronger shifter plate which may be part of your problem. I'm assuming you have a Muncie or T10 BorgWarner. Muncie4speed.com is another, vetteproducts.net, pipersauto.com (then go to 4 Speeds by Darrell Shepherd)
Hurst has a "how to adjust linkage" page on their site
I've recently got a Hurst for mine because the old linkage just wasn't worth dealing with.
good luck on getting it fixed soon, that makes Vettes look bad

Now there's a whining sound around the tranny area that speeds up with tire rotation and not engine rpm. I checked drive shaft and its not touching anything. I think the tranny is about to go.
