Need help on 5th gear rattle

[owredneckmike]

Here's a good one for y'all. I've got a NV4500 recently rebuilt and everything works great... . except when in 5th gear the gearshift starts a high pitched rattle at around 1800 rpm on up. When even light pressure (one finger) is applied to the stick pushing toward the passenger side the rattle will stop. I tried replacing the shift tower because I thought it might have excessive slack, but that didn't fix it. Seems like it's rubbing against the 3rd gear shift rail, maybe? I tried adding shims from the old shift tower to the new one to increase spring tension and got worse results... So I removed shims to lighten the tension which helped, but not only did it not fix the problem completely, it's like shifting with a wet noodle. Any ideas would be much appreciated.

Who rebuilt it? Is it possible they didn't tighten something properly?

You might get more responses to this question in the 2nd gen forum, as there are lots more NV4500s over there.

Isn't there a 5th gear nut that has to be torqed right??

That's a good idea to move it to the 2nd gen forum. Thanks Ryan.
