Hi starwarrior,

Sorry for the delay in replying.

From the symptom descriptions, most probably the A/T Control unit (ATCU )is bad or has a shorting in the wiring circuit.

I would like to confirm if it is Fuse "K" that is blowing when in Auto mode?
Was any repairs carried out prior to this happening?
Was any trouble codes retrieved from the ATCU ?
