Is it a GTt or 25GT?
Have the solenoids been replaced with brand new items or tested ones? The reason I ask is the ones out of my old car that were dodgy always worked fine at room temp, tested fine etc etc, but when at operating temp they went open-circuit and threw the code.
When the ENG A/T CONTROL fuses go, lots of funny things happen, nerver seen it throw a solenoid code, normally just makes the car stall and drive like shit.
