I have the 3.1 Lumina (auto).
Yesterday I went to shift into gear and it was harder than usual, I have to use a lot of force to get it into 2nd and 1st (not that I ever use them).
Looked like the problem went away and today I could barely shift into (D). I turned off the car and turned it back on and it seemed a bit more loose but still nagged me so I tried again and it was then loose.
Im guessing gear selector cable, but im a novice. Could it be my tranny going bad? Ive heard of it happening in cold weather. But its 93 today here in Florida so ive ruled that out!
