My 02 took a fit of jumping in and out of od and lockup. Then it quit and worked perfect. Then a couple weeks ago it had been working perfect then I took off and it wouldn't shift past second so I stopped shut it off and then it wouldn't shift out of first. I parked it till today when I needed to move it so I took it down the road and it shifted fine. I didn't go far enough to go into od or lockup but it hit second and drive perfect. What would be the deal? I'm sick of these transmissions but I want to fix it before I sell it I think.
