LOVELY!! I have the same issue(s) with my '01 Ranger 4.0 Automatic Trans.
I have a few problems with mine and more... I have the 250mA drain, the cruise light flashes when the button is pushed but won't engage, my 4x4 won't engage, and my Airbag light flashes.
Anyhow, It's nice to have some ideas as to where to start the investigation this weekend!
I will post my findings.
