Good questions. I too have questions. I have an 04 F150 4x4 with the automatic switch on the dash for 4 wheel drive engagement (2wd/4hi/4lo). I found out yesterday that on slick roads that the 4x4 doesn't actuate right away. My question is: Does the manual transfer case engagement (lever on some models on the floor) engage the transfer case and does it lock it in 4x4 instead of a solenoid engaging 4x4? Also can the auto engagement be swapped over to the manual lever engagement? What are the pros and cons to doing this and also can I even do this swap?
