2002 Explorer
alright, several things. Background on my vehicle: 2002 ford explorer xlt 4x4 bought used from individual about 6 weeks ago. 134k miles. currently getting about 18mpg on highway, 16mph in town. recently replaced thermostat, thermostat housing, and head gasket. had transmission serviced and transmission filter replaced. mechanic said transmission didn't seem to have been serviced before.

1) got a small kick when auto trans is shifting around 30mph and around 45mph. this got a little better after trans was serviced.

2) overdrive switch nor 4x4 switches work, lights on dashboard light up when cranking vehicle, but don't do anything when switches pressed. 4x4 switches worked when I first got the vehicle

3) when turning right or left from a dead stop, the vehicle shudders as if running over a rumble strip on the side of the road.

4) since having these issues, i've removed the Control Module to see if this would help any of the above issues. obviously the 4x4 buttons will no longer work with the CM removed. Sidenote related to CM, battery has not been removed or changed since I've owned vehicle.

5) service engine soon light just came on. took it to auto zone and they said it read as a bank 1 and bank 2 problem.


any suggestions would be appreciated. I am mechanically inclined enough to check things on my vehicle, I owned a Toyota Corolla before this vehicle and felt like I had near about replaced every bit of it before it was all said and done.
 






The tranny kick could be the tranny mounts. cheese to replace...
I had the same prob with the 4 by 4 lights on the switches not working. have somebody inspect the front and rear tires in some sand in 4 wheel drive and see if all 4 kick up sand. if so your 4x4 works. if they do not work, check the fuses.
the turning shutter issue could be bad struts...
bank 1 and 2 would be either the cats or the o2 sensors good luck bro
