there seem to be a fair amount of GTP owners at this site. some of you may have have a shift kit installed or even done some tranny work. the accumulator has the 1-2 and 2-3 piston/spring assy's inside. do they ever stick over time? causing delayed shifting or maybe even slow downshifts? I get a quick tranny buzz at about 10mph when i stop. maybe i asked the wrong question before. I did change the filter/fluid. looks clean. a tranny shop might be next. i hate to get taken for a ride by a shady shop.
