Default transmission grinding..

got my transmission fluid changed today in my 2000 Camaro SS M6 and i noticed a couple times today after the fluid change..that when i would be coasting about 5-10mph and i would go to put the car in first..say i was coming to a stop sign..that the it would grind..this has never happened until today..and it happened a few times..and i had my tranny fluid changed this morning by valvoline...is there any possible problem..or just pure coincidence?

Your syncros, very common. Or possibly, but not as likely your clutch is not fully disengaging. If its the clutch it should do it in all gears.

Did you have them install synthetic fluid? I have seen that cause similar symptoms in the past.

Its hard to say but they might have installed synthetic ATF in it and now its too slick for the syncros to operate correctly .

No you want to use regular ATF or syncromesh in it if you drain it .

Correct. We prefer ATF Type III.
