I have a LS1/4l60e with only park, reverse, neutral and first gear with no error codes. Manual shifting makes no difference, still first gear only. After checking vss and tps (both good) I unplugged electrical connector on transmission trying to force limp mode and third gear but still only first gear.

Are there any other checks I can make or is a rebuild in order? Could it be a solenoid?

Thanks in advance for any help

Did this problem suddenly start happening or did you do some transmission work?


You will be asked by others here about line pressure, so if you have a pressure gauge I'd go ahead and do that.

It just started all of a sudden. I'll try to get line pressure asap.
