Try flushing the transmission fluid first.
That probably won't fix it, in which case it needs rebuilt.
This goes under OEM Tech, not Chat.

You mean you have to manually select your gears 1-4 It won't shift at all?

It just hits the limiter until you do it yourself?

go get a tranny at the JY and throw it in. problem solve for a few hundred bucks

Have a transmission shop check it out before you spend any money on junkyard transmissions and tranny flushes. It could be something as simple as the throttle pressure cable being disconnected or out of adjustment.
