I'm in on the MAF. I changed out my Intake cam sensor and was instantly greeted with the Trans lamp on start-up! Um, I forgot to hook-up the MAF connector. Scared me good but never could figure what the @#$ MAF data has to do with transmissions? I thought the evil programmers at Siemens just liked to scare us.

RB's post helps understand why MAF "load" data is involved.
