Default 1990 auto trans shifts too soon

Just had my tansmission replaced with a used one. No telling how old
the used one is. This replacement transmission shifts way too soon out
of first gear -- in fact, it shifts so soon, that when I'm idling in
rush hour traffic without my foot on gas or brake, it shifts into 2nd
gear!!

Anyway, is there an adjustment to the transmission or perhaps a vacuum
hose that's leaking, or something that I should go back to the mechanic
to check. Also, I notice the "power" light, for the power shifting
configuration, only comes on sporadically when it should; but my old
transmission did the same.

Thanks guys

The "power" indicator must be constantly ON when the selector button is
pushed in,
othewise, the norm indicator must appear, unless the bulb is burned
out.
Next, make sure that the TV (kick-down) cable is attached to throttle
control lever and/or does not have extensive slack. Check all wiring
connectors on the transaxle.
Note, however, that these are just general suggestions, because I have
no idea why the orig. transaxle was replaced, have the ECT computer code
scan been performed due to the shift problems,etc.
