Hello all,
It's been a while since I posted here, had my transmission rebuilt about 3 years ago, and it's mostly worked fine. I determined that it needed rebuilding after going throught my valve body with the help of Glacier and others here, and putting in a shift kit and some of the upgrades. Now I'm back asking about something that I think has been around for a while but I only recently figured out was a transmission issue. When I'm traveling at high interstate speeds (80-90 mph) and need to downshift for a hill, the transmission vibrates at a fairly high frequency while shifting. It feels like I'm driving over those ridges on the edge of the road designed to wake up drivers that are dozing off, but maybe a little higher frequency and a little less intensity. It only does this under load and at high speed. I think it's in the shift from 5th to 3rd, although that's just a guess. Anybody have any ideas on what this might be?
