My trans grinds when shifting Into 3rd only at high rpms or hard accel but when normal driving it shifts fine no grinds. I also noticed one time I had a hard time shifting into reverse gear would just not go In, is my trans messing up already the car is at 60k

The first item on the trouble shooting chart for any kind of gear shifting issue is to flush and bleed the hydraulic clutch system.

That was the first thing I did cuz I noticed my pedal would stick to ground on hard accel so I bled it but it still does it but pedal don't go all the way down anymore but I did notice my pedal got a lil stiffer with the bleedin which felt way better... I also noticed that sometimes my gears grab nice n somtimes they feel sloppy when shifting like the shifter feels loose

If the clutch hydraulics are not an issue, the GM trouble shooting procedure calls for two tests. One is to establish whether the transmission can be shifted from neutral to any other gear with the motor not running (static test). The second is establish whether the transmission can be shifted from neutral to any other gear with the motor running (dynamic test). If it fails the static test the issue is likely with the shifter, or transmission mounting. If it fails the dynamic test, the issue is likely inside the transmission.

Having said all that, the pedal sticking to the floor symptom can indicate a failing clutch pressure plate.

good luck with that, I've got another thread going with similar issues. Had a reverse grind; dealer pulled the trans, rebuilt and now they say 3rd grinds at higher RPM's... so now I wait....

I just bumped the thread to which the link pointed - it is the thread to discuss orders for that shifter.
