I popped in some 2" spring spacers recently. When I took the jeep (2000 TJ) for a test drive there was some slight vibration at higher speeds. So I put some 1/2" spacers under the tranny skid plate. This solved the vibration, but now I'm having some trouble shifting into 2nd (manual) when the tranny is cold. I never had any shifting issues before this at all.
Has anyone else experienced this?
