Default Trans grinding from 1st to 2nd

Anyone have any idea why my trans is grinding when i shift from 1st to 2nd? it only happens under really hard acceleration and doesn't happen all the time. any ideas besides me having to rebuild my trans?

Default if you're grinding gears on high RPM shifts it can be an early sign of a synchro failure

or you're just not depressing the clutch all the way on the shift or engaging the clutch in between shifts.

Default the 1/2 shift is the hardest...

since the ratio's are the furthest apart. i grind sometimes, but not often. if it only happens ocasionaly you should be ok. try changing the gear oil befor you do the supercharger. and get a spectrographic analisis done on it to check for major damage.<ul><li><a href="http://www.car-videos.com/tools/speedrpm.asp?Car=Select&amp;Num1=205&amp;Num2=55&a mp;Num3=16&amp;AxleRatio=3.889&amp;Ratio1=3.5&amp; Ratio2=1.944&amp;Ratio3=1.3&amp;Ratio4=.943&amp;Ra tio5=.789&amp;Ratio6=&amp;Ratio7=&amp;Redline=7000 &

Default if it grinds, maybe u should keep double clutching into second

second grinds occasionally for me as well. double clutching is the trick to not grinding to almost any gear for me.

I agree with Paul. If you're still on warranty, take it to the dealership.
