Hello. I may need a replacement PCM. The part number for the one I have is 4L3A-12A650-ABM. I cannot find any with the "ABM" designation. I was told that one ending in "ABH" is the correct replacement. Anyone know if this is correct or not? This is "new" territory for me. I have dealt with a PCM before.

 

I don't know the answer, it was my curiosity as to what a "Trinitron" engine might be that lured me here.

I vaguely remember a TV named such.

 

Yeah... another senior moment....again,,, I think the correct nomenclature for that engine was "triton." This getting old sucks.....
