I have an 1989 gt mustang! engine rebuilt, tranny rebuilt with b&m shorty shifter, new drive line, 3.73 gears... when im driving 4th and 5th gear the shifter rattles really badd, even when im driving in 4th or 5th gear and put it on neutral same thing.... we even lifted it off the frame and still same thing any solutions please

what about if you leave it in gear and just push the clutch in?

I had the same problem before (maybe)?
My shifter vibrated very bad to where I couldnt stand to drive the thing no matter what gear I was in. It ended up being the hermonic balencer. It was worn out. Put a new one on and it was fix.

Now that's why I said (maybe) you have more work done then I did at the time. I'd take a look also at your drive shaft if it's all bolted down right and also look at your tranny. See is the tranny mounts are up to par along with making sure the bolts are tighten down to where they need to be.

If it is just the shifter handle buzzing when in gear or nuetral it is simply the harmonics in the tranny being transmitted up thru the shifter.

You can remove the shifter tower assembly from the transmission and when you do, look down inside, you'll see that the shifter is seated in a plastic cup on the shift rail. This plastic cup wears out over time and doesn't hold the shifter stub tightly anymore like it did when it was brand new. You could try taking a small flat washer and put it down inside the cup and then reseat the shifter stub into the plastic cup. This will "tighten" it up again and likely, eliminate the buzz. If you'd like, I can send you a new plastic cup. I have thousands of them here from TKO's and T45's but I think they were the same cup that was used in the T5.
