Hi all. I recently changed my transmission filter and fluid on my Chevy Blazer problem is now though the when I shift into reverse it wont budge as if it is stuck in park. I have been told that I may just have to adjust the cable, anyone able to tell me how to do this? Thanks!

Well all who looked over this, I sorted out the cable but it still wasnt it. I went to store and got a diagnostic tester and it said my shift solenoid had a problem. Took the pan back off and there it was hanging down, seems I busted it somehow when I was putting the pan back on!
