6 speed manual transmission 2005 Tacoma grinding.

I'm narrowing down possible, hopefully, cheap fixes for what is going for me. One guy helped me towards the shifterbushing, got that on order now. So on to next possibility, I have read of people having issues with grinding in 1st, 2nd, 3rd... Maybe 4th gears when the trmpature drops using redline mt-90. I'm going to check my tranny fluid today, but besides possibility of shifter bushing, maybe to little tranny fluid and or issue or the cold with mt? Anyone else know of or experience issues grinding like above that were fixxed after fluid change or warming up for a bit, driving off cold is a sure winner if I wanna gride going into 2nd or 3rd. 5-6 and reverse are always good even when cold though.

 

could be the clutch issue
