Ok took the truck this morning it was fine i havent had a problem until now this afternoon i was leaving mu buddys house and i pulled out of his driveway and it slamed 1st then 2nd then 3rd it slammed all the gears real hard i checked the fluid and its fine not burnt or black what do you guys think i hate to hear its a blown trans i just lost my job and im broke ha ha my luck Thanks alot Adam

It could be a bad Force Control Solenoid, I think thats the name of it, it controls pressure in your trans. If it or the wiring goes bad the trans goes to full pressure. You might ohm the solenoid through the case connector terminals and see what you get.

What codes are you showing?

ot getting any codes its not doing it now but it seems to be shifting into od too soon now and at like 50 mph i step on it it makes a funny grinding noise what could that be im stumped

drop trans pan check for metal only thing in trans to sound like grinding are planetary gears
