Will be changing the transmission oil in a few days.
Mongoose Cable with Toyota Techstream software
I have further checked with the active injection tests for AF2 sensors. The Toyota specific code mentions "rough idling" and it does have rough idling, the idle should be above 600/650 but it drops to the range of 500 at times. While the DTC is triggered when it drops to less than 400. Spark plugs and coil boots are checked as well, they are okay.
The brake pedal has been spongy even though the brakes work fine (the pads are as well) and there is brake dust on the rims visible in a few days use. There's an issue with the brake booster/vacuum switching valve I think, the same is written under the rough idling issue areas. Sorting it out.
