Just rebuilt, when you place the shifter in OD it won't shift out of 1st. If you put it in D it all shifts and works fine. I'm lost, any ideas?

 

First, are you sure it is 1st and not 3rd due to being in Limp mode?
And you are sure the shifter/cable is working properly?
You have Park, D1, D2 and D3?

Sorry, I cannot think of any way you could end up with such symptoms other than something stuck or leaking in the Valve Body or its gaskets.

Perhaps one of the pro builder knows or has an idea.

 

yes it is working fine as long as you are in D and not OD when in D it has all gears and works fine, when in OD it will not shift out of first
