Hi ZeN, what constitutes the brake switches being OK? I did a quick run last night with the Datascan III app. Car seemed to be ok last night, that's rare though.

I've attached the DataScan CSV if anyone can tell me how to interpret it

Theres 3 data PID that you can pull for brake switch. As long it switch from off to on or vice versa when you press or release the brake, ecu registererd it and that was not the reason your throttle were limited. You did said above that sometimes you had to wait up to 6 sec before it scream.

For the transmission, it could be valvebody going out.
