I have a 4L60E transmission. I had it rebuilt. It
shifts up and down fine, but sometimes you stop at
red light it won't shift down. You manually put it in
first gear and it's like it's in second gear. You
manually shift to drive it shifts out. Then when you
shift to overdrive it shifts to overdrive. When you
press gas down. It down shifts to drive like it's
supposed to. You can shut truck off and get in it
the next day and won't have any issues. Any ideas
to what could be going on.
Who rebuilt it ? you should ask them .
