I have a 2000 silverado with the 6.0 L 4x4 and the transmisson all the sudden began slamming into gear! Then after a couple miles it stopped and was shifting perfect again! It keeps going back and forth from perfect to slamming in gear. When it's shifting hard it's while only upshifting it never shifts hard will downshifting. Could this be a speed sensor OR a bad solenoid OR both? I would appreciate some info. I've owned the truck less than a week and I'm wondering if I should take it back to the dealership or if it's a common and/or simple fix?

When its happening does the check engine light comes on? If so have the computer scanned for code/s

You should take it back to the dealer and have it further checked and tested-

No check engine lights come on at all! I tried to do some research on the internet and from what I found it sounds like the speed sensor or the solenoids are going bad.

I'm hoping that this is an easy fix, and if so I would rather not deal with the hasle of going to the dealership.

I had a 3500 6.0 4x4 doing this and the issue was throttle position sensor. I replaced it and issue was resolved. It was very intermittent. Hope this helps

"RAZMATAZ" I've tried disconnecting the battery cables and making contact with the negative and positive cables for an hour then hooking back up and letting truck idle for 15mins before driving truck. Hoping to reset the computer. I was getting curious so I tried something. When the truck started acting up I pulled over and shut the truck off and took the key out of the ignition for about 5 seconds then started the truck and started driving again and the truck was shifting fine again! I tried this several times when the truck is acting up and every time the truck starts shifting fine again! What does that mean?
