How do I put my 1995 gmc in 4 wheel drive from in park or newtra
Neutral is correct, then it may take a few feet for it to completely engage.
You should be able to go in and out of 4x4 while moving (up to about 55 MPH) or stopped. Doesn't matter if the selector is a manual shift on the floor or push button on the dash. That being said 4low is a different story. You have to be stopped and the transmission has to be in neutral before you can select 4 low. Then put the transmission in reverse or drive and off you go. Top speed in 4 low is about 30-35 MPH. Shifting back out of 4 low is done the same way. Stopped, in neutral then select 4 hi or 2wd.
