Trooper 2002 Transmission Problems

Can some one please help, I have a trooper 2002 6cyl 3.5, the problem i have with the transmission only works with the winter drive botton in (D) I don't know why but when I stop at any light I need to press this botton to the 1st shift then after 5 mph all the other shifts works perfect, I replaced one Selenoide, and it didn't work I don't know what to do next, I need to know how many Selenoide's this transmission has, I don't know if the transmission was damaged at all or if it is a Electronic problem.

pull the winter button and unplug it and see what happens.
