ok i changed my tranny fluid with honda mtf about 3000 miles ago and the car shifted as notchy as usual but i had less 1-2 grind but yesterday i grinded from 2-3 at about 7000 rpms and for some odd reason my 5th and 6th gear were really hard to put in and outa gear well after siting in the garage for a while i turned the car back on and drove it out again and it seems all my gears have like a double cllunk noise when they go in and 5-6 gear are a little bit harder to put in then the rest. i did a search on it and sounds similar to other but not exactly. i can take it outa gear without the clutch while its moving but 5-6th gear are stiffer then the rest. and when the car is off i can put it in to all gears fine but 5-6 also is a bit rougher when it feels like it so when the cars off about 50% of time it goes in smooth. i just had the clutch fluid bled about a month and a half ago and it looks fine. im thinking of trying GM synchromesh "miracle worker" and seing if it helps any. anyone have any advice they could give me? i have an 03 suzuka with est 54.000 miles so no warranty
