Trans noise

[Turboteko]

I have a '83 Cab and replaced the bushings in my shift coupler and it shifted good but transmitted a lot of rattling noises in 1-4th gear but not in 5th. After a few months I went back to standard bushings and that seemed to quieten the rattleing noises a lot, my question is, do the Wevo type couplers transmit noises, i'd still like to improve my shifting. I'm using a factory short shift shifter.
