just bought the truck knowing that it grinds from 2nd to 3rd and 3rd to 4th. every other gear is fine. now i checked the bushing at the clutch pedal as i searched on here and found the plastic bushing gone. replaced the bushing, the metal bracket and had to replace the master cyl because the eye on the rod was broken also. it has gotten better but i still grind. i changed the fluid to synth atf and no much help. i changed the fluid again to synth MTL and now when the trans is cold it shifts fine with 3rd to 4th a small grind. my question is can i add something so it wont grind? clutch is good. i believe i have the DMF and i do not know the condition of it. also i do not know the condition of the pressure plate.
