08 v8 Touareg transmission in LIMP Mode - Transmission Output & Input sensors Malfunctioning

I have a 08 V8 with 145k miles

I pulled codes of VCDS:

P0720 - Circuit Malfunction - Tranmission Output Speed Sensor (G195)
P0715 - Circuit Malfunction - Transmission Input Speed Sensor (G182)

I been reading on G195 its under valve body inside the gearbox, never done ATF change on treg.

Seems like both sensors is close to each other, but don't seem like a common issue.

I checked all fuses, no fuses burned, I checked fuses up front in phelm box and fuses next to battery.

Is there a Transmission reset on VCDS ?

Any one with same issue or knowledge please advice, I don't mind replacing sensors but weird both is malfunctioning, as far as I understand both sensors helps the transmission shift based on speed on gears.

I can drive the Treg, it goes in gears but its almost like the gear box shift to early or late, I have not driven the Treg, Much after my girl friend informed me of weird movements.

Log outputs of both sensors to get a better idea. Are you getting any readings from them or are they reading a constant value or what?
Are you asking how to do logs or which MVBs to look at, or both?
You'd get values from the corresponding control module (transmission) in advance measuring blocks or similar.
