When I'm up around 6 and 7k, my shifter starts shaking a little and making a high pitch vibrating or grinding noise. It happens in ever gear. Anyone have any idea what this could be?

By the way, this is a Hydro Ls tranny with a 6 puck clutch.

 

how old is it? those six puck clutches are not the best for longevity...

 

I don't know old or how many miles it has on it. I bought my car last fall and it came like this.

 

I don't know what the problem is but I have had the same problem since I switched my shifter bushing to some new ones. Maybe its cheap shifter bushings?

 

Maybe, someone else was telling me it might be the imput shaft bearing.
