I noticed much less shifting grind once I switched out my tranny fluid to GMSFM. That stuff is getting harder and harder to find these days. Less impressed with a clutch flush.

great, i was planning on changing my own tranny fluid in a few days

have we determined that the trans fluid change was not the culprit but the Clutch Master cyl?
IF I had to take bets, I'd be betting that it got a lot better after the clutch fluid flush...

It's been a couple of years now, but I remember the new Honda MTF seemed like I poured sand into the tranny instead of fluid the first time. I was so dissapointed that after a couple of days, I ordered some AMSOIL MTF to replace it. But, by the time the AMSOIL arrived, the Honda MTF started to feel pretty good. Then after about 500 miles, I was convinced that the new Honda MTF was the ticket to shifting nirvana again.

Moral of the story? Stick with it for awhile to see if things improve. If you over-filled the tranny, then that could be a problem too. Overfilling could cause aeration/foaming. Air is not a good lubricant. I also noticed that you have to turn the bottlew a few times to mix the additives. Not a big deal for the first quart you use. But since you will only be adding about 3/4 of the second quart, you want the additives to be mixed well.

It's his master cylinder leaking thats the culprit guaranteed.

It's not hard to change tranny fluid. Just put the car on jack stands as level as you can and fill it up until it starts to drain out... let it stop and torque the fill bolt again. A slight overfill or a slight underfill is pretty much impossible if you can get the car semi-flat but it's not the end of the world either way.

If its not the master cyclinder you might want to try GM syncromesh
feel much better in mine than Honda MTf

The Honda stuff feels ok at first though then goes bad after a week or so

^thats weird.

My clutch master was also leaking...I developed a bit more 'grinding' into all gears... figured trans fluid was at fault, but I bled the clutch anyways. The master is still leaking slowly, but now the clutch engages much better and the pedal feel is much stiffer.

I need to go buy a new Master Cyl, I guess...If the OP's master is leaking, then it makes sense that the gears will grind.
thats exactly what my problem was... it just curiously happened the same time i did the tranny fluid
