2000 Nissan Maxima

Transmission problem
2000 Nissan Maxima 6 cyl Two Wheel Drive Automatic 153000 miles

I have a 2000 maxima, the car would not shift to 4th gear and the overdrive is not working. I replaced the transmission with a 39,000 transmission from an accident car and I am still getting the same code saying the transmission solenoid is faulty. Is there another thing I should check before I send the transmission back to the junkyard. Note the other gears shift okay.

The transmission solenoid itself is what allows an automatic to shift into the overdrive gear it would be a lot cheaper just to change this first.
