Hi folks

Here's an oddity that's happened twice in the last few days:

My BAS/ASR and ABS lights came on...after some brake pulsing (on a completely dry road) so I figure that's either a sensor or brake switch, no biggie

But then inside 1 - 2 minutes the check engine comes on, which is odd. I put the OBD reader on it says there's a P0700 (transmission related) fault, which I clear. Later in the day the ABS lights go out, on their own.

The next night the whole thing replays itself, a few brake pulses and then the BAS/ASR and ABS lights come on, 60 seconds later the check engine light returns...


What would be the common problem that would activate both these seemingly unrelated warnings?

Thanks
