my bronco won't shift out of 1'st gear on its own ( automatic transmission ), but i can maually shift it from D-1 to D-2 then to D-3 and it shifts fine. What's the deal, is it just linkage problems or what?

Check your modulator valve. Is your vacum line hooked up? This is the first place I would start.

Click to expand...

the modulator is a diaphram assembly on the passenger side rear of the trans. you need to supply it with manifold vaccuum. Check all hose connections.
